Shorter and shorter product life cycles in the Consumer area have led to it, that also many industrially used electronics components already after one or two years are only difficult to get or not available anymore.
That an electronic component sometime is obsolete , would be nothing unusual, if not the product life cycles of the individual components and the final products would run ever further apart. For enterprises in industries like the military, railway, power station, automation and medical technology, where products must be as invariably as possible supplied over many years, both the production development and the cost calculation thereby more and more often to the tightrope act, stresses Klaus Kruse.
However in Germany the costs caused by obsolete components no longer available on the regular market move in the meantime in the three-figure million range. The damage caused by counterfeit components is not yet taken into this account. In the long run , if you are a manufacturer of long-lived industrial goods one will not come past arguing with the topic Obsolescence. “
As the most effective protection from unpleasant surprises by component obsolescence or changes – Klaus Kruse recommends changes already begin in the evaluation phase of a new product with the Obsolescence process. „ Argue before the development with the prospective availability duration of the necessary components and possible alternatives , afterwards every now and then very much money helps itself to save, because the additional exchange of individual components or complete Redesigns are just connected with high risks of costs “, Klaus Kruse means.
With the examination and evaluation components endangered by parts lists on risky obsolescent is mostly not yet done possibly however. The fact that there is not the one Obsolescence solution absolutely but for an effective Obsolescence strategy usually a whole set of measures is necessary.
Karl Kruse’s solutions range from complex components with integrated databases for discontinued forecast about international procurement management, Replacement-ICs, long time storage draughts, engineering, Rework and Electronic Manufacturing service to the aftermarket production discontinued
Components and development of customized Replacement ICs. „Our aim is to sensitize CEMS, manufacturer, distributors and the users stronger for this subject. There will never be the absolute protection from Obsolescence though, but many possibilities of the risk minimization of which we want to give an understanding and pass it to our customers .“

AEM Components announces the availability of its new line of AEC-Q200 qualified surface-mount fuses designed specifically for reliable operation in high-stress automotive applications. The new wire-in-air AirMatrix (QA Series) and solid body SolidMatrix (QF Series) fuses are manufactured in AEM’s TS16949-certified facility. The two product series together offer automotive design engineers with products that assure reliable performance in applications ranging from engine controls and battery-management systems to infotainment and communications systems.
The QA Series features the industry’s highest current ratings — up to 20A/250V. Its proprietary, hermetically-sealed wire-in-air structure assures consistent electrical performance The QF solid-body fuses utilize AEM’s proprietary, anti-sulfur end-cap construction and provide superior mechanical and thermal stability over a wide temperature range (-55°C to +150°C).
The fusible element in the QA Series wire-in-air devices is uniformly straight across the internal cavity and externally bonded to the endcap through the plating process .Competitive units utilize solder beads inside a ceramic tube to bond the fusible link. This traditional approach has the drawback of non-uniform performance and potential internal connection failure caused by mechanical/thermal stress like vibration or bending, or by common soldering defects like cold joints or poor wetting. Under high-stress conditions, the solder can vaporize, causing prolonged arcing that can lead to package failure and damage to the circuit board and surrounding components. In comparison, our automotive-grade fuses are designed specifically to enhance reliability in harsh environments by eliminating the solder joint.
The QA Series is offered in two fast-acting versions: a 2410 package with a 0.5-20A/65-250V rating and a 1206 package rated at 1.5-15A/32-65V. Auto-grade QF parts are offered in fast-acting and time-lag versions, and in 1206 and 0603 versions with current ratings up to 8A.
Today, AC and DC fans have more demands placed on them than simply cooling andcontrolling airflow in white good applications. From refrigeration and freezer units toconvection ovens and stove range venting ducts, white good manufacturers require high-performance, energy-efficient fans and fan trays that feature speed control, remotemonitoring, low noise levels and wider operating temperature ranges—all while reducingpurchase and assembly costs.AC fans, DC fans and blowers are now available with features that address the demands of low noise, low power, increased functionality andhigh reliability.
Designs utilizingfans with “smart” controls optimize the fan performance, while also minimizing energy consumption. Smart thermal controls can reduce power consumption by as much 30%, while reducing noise levels, as the fans only operate at full speed when needed.
Smart fan control options can also include tachometer output, airflow monitors (as an added accessory), locked rotor alarm, pulse width modulation (PWM) input, and constant speed controls. These intelligent control options allow the end users to better monitor their product operating temperatures and the fan’s airflow, while ensuring the fans are operating properly and at optimal conditions.
Image: Airflow modules provide a cost-effectivealternative for indicating airflow in AC and DC fan/blowerapplications
Tachometer output, for example, provides design engineers with an accurate means of monitoring and reporting a fan’s rotational speed, as well as indicating if the fan’s speed falls below a certain RPM. This can be used as an alarm trigger or indicator by monitoring the fan speed to determine relative temperature. Typically, the tachometer output option is available as either a 5V TTL signal, or as an “open collector” signal.
Airflow monitors provide a cost-effective method for monitoring and maintaining proper airflow in AC and DC fan/blower applications. These modules can indicate airflow or lack thereof with an optical LED and/or audible-alarm when airflow falls below 8.2 ft/s due to fan filter clogs or interference with the fan blade. Able to mount via clip or clamp to any grill, airflow monitors are field retrofittable and can install perpendicular to the front or the intake side of the fan. With a long-operating life of more than 100,000 cycles, airflow monitors are rated to IP20, NEMA 1 certified, and have an operating temperature range of -20°C to 50°C.
DC fans and fan trays can be equipped with locked-rotor alarms indicating whether a fan is running or has stopped by transmitting a fail high or fail low output signal, minimizing fan downtime and averting an overheating situation. A PWM option also allows users to digitally control the speed of the fan through an existing bus system or PLC.
AC Fans or fan trays with thermal speed control employ a thermistor-controlled circuit that increases fan speed only when the temperature rises above a determined set-point. This reduces overall energy consumption by lowering fan speed when temperatures within the enclosure are below the set-point. Thermistor control circuits can be mounted directly in the fan hub or remotely mounted via a lead wire, and can be positioned anywhere within the enclosure, giving design engineers the flexibility to regulate fan speed based on ambient temperature in a specific area. The constant speed function senses variable input voltage, which causes variations in power output, and maintains the fan’s constant speed regardless of input voltage fluctuations.

maximizing energy efficiency in microwave and oven applications
Lowering the Volume
Low-noise fans in refrigeration units, coolers and range hoods are being used to perform different functions while reducing the amount of noise normally present in older product designs. Low-noise fans are often selected for refrigeration and wine cooler applications to prevent condensation yet not contribute significantly to audible noise levels.
Condensation can build up on the inside of these units, forming not only on the glass, but within the enclosure itself. The use of an internal IP55-rated fan creates just enough air movement to prevent condensation. The same situation exists in store refrigeration units. Available in both AC and DC configurations, low-noise fans are employed in these applications not only to prevent condensation build-up, but also to minimize the noise level and reduce power consumption.
Electronically Commutated Fans
Electronically Commutated (EC) fans utilize a brushless DC motor with a single or universal AC input. EC fans incorporate voltage transformation within the motor to provide a low power, dual speed fan. In addition, EC fans are programmable to deliver even more power savings. Well suited for large refrigeration units and chillers, EC fans offer a low power, energy-efficient cooling solution.
Components exposed to harsh environments including high heat are susceptible to failure over time, with fans being no exception. The classification of the insulation system is based on the lowest rated component in the system, and in many instances may be the fan. The materials and parts specified in the construction that affect the insulation class include the motor winding, the wire and the insulation on the wires, the enamel coating on the magnet wire, as well as the visible parts of the fan or fan tray such as the frame and impeller.
In white goods applications, AC and DC fans must be capable of operating within extreme temperature ranges, from cold freezers to extremely hot convection ovens. Different materials and designs are available to achieve the necessary performance and reliability across a variety of applications.
A high temperature fan with higher insulation Class B or F construction often eliminates or reduces premature failures caused by inadequate airflow in hot areas. AC fans are often utilized in high temperature applications such as oven control assemblies and forced air convection units. The temperature of Class B insulation is specified at 130°C, while the temperature of Class F insulation is specified to 155°C. These maximum temperatures at which the plastic and insulation materials are rated includes the normal temperature rise of the fan, so care must be taken to ensure these ratings are not exceeded in these types of applications.
Image: All-metal fans, like the one shown above from Orion, are capable of employing high insulation Class F materials for use in high temperature oven applications
All-metal AC fans satisfy size, power and compatibility issues in the most rugged white good applications, such as HVAC and commercial deep fryers. All-metal fans are resistant to high temperatures and corrosive compounds, which may facilitate longer life expectancies in harsher environments.
Customization and Value Add
Fan technology allows manufacturers to customize their fans, fan trays and blowers to meet application requirements. Whether it’s the airflow, noise level, alarm output, IP- rating/NEMA protection, or a special feature, fan manufacturers can meet the specification required.
Not all fan manufacturers offer on-site connector, harness and bracket assembly that simplify the fan installation process for white good manufacturers. Fully assembled and tested fan trays provide white good manufacturers with additional benefits by lowering supply chain costs, reducing lead times on materials, reducing the number of SKUs, reducing parts inventory, simplifying installation, improving quality and lowering overall production costs. Not only does the tray provide a complete solution, it reduces part numbers and stocked inventory of cooling parts from tens to one. Tray manufacturers like Orion Fans also assemble, test and ship when needed, further reducing lengthy lead times.
With more capabilities available than ever before, including higher temperature ranges, speed controls and tachometer output signals to name a few, manufacturers of white goods are using fans as a means of providing increased functionality, maximizing energy efficiency and decreasing end unit cost.
