Embedded Antenna Solutions

Helical Antenna Integration
We really like helical antennas, and our Helicore antennas are ideal for custom integration.Unlike many helical antennas, Maxtena’s Helicore Technology allows for easy integration and embedding. We typically use a standard 3-prong connector for embedding purposes, but our helical antennas can be easily customized for integration.

GPS Patch Antenna Integration
We are experts when it comes to integrating GPS patch antennas into any housing.We are pretty familiar with patch antennas, and we know how to get the best integration for the best price point! We’ve got great tips and tricks for your to try, or we can assist directly with your integration.

Custom Connectors
Most of our off-the-shelf products can be tailored to your project! Our off-the shelf antennas are great for many applications, but sometimes SMA connectors don’t cut it. When that happens, just let us know! We are able to customize our products with most standard cables and connectors.

Prevention Becomes More And More Important

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That an electronic component sometime is obsolete , would be nothing unusual, if not the product life cycles of the individual components and the final products would run ever further apart.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’ Automotive-Grade Surface-Mount Fuses Deliver Performance And Reliability Improvements

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.
