GCTs MEM2075 Push-Pushes Slim MicroSD Connectors To The Limit

One of the slimmest memory card connectors in the market with a push-push ejector type, the MEM2075 has released by GCT. Making it a super-slim option for engineers where there are space limitations and height is a defining feature in their designs ,the MicroSD connector has a profile height of just 1.4mm The product length with card inserted is also a mere 17.25mm, adding to its credentials.

As well as the compact form factor, co-planarity is less than 0.08mm, ensuring profile is kept to a minimum on a PCB. Four PCB retention tabs in “V” profile also give the MEM2075 maximum mechanical strength versus competing products.

The connector is available in a stainless steel cover and latch with SMT contacts. With PCB locating pegs as an option, a card detection switch is present in normally open configuration. The connector has been tested to 5000 mating cycles and operating temperature is between -25°C to +85°C .

“The MEM2075 takes the conventional MicroSD connector and pushes the boundaries on the physical dimensions,” commented Paul Hulatt, Product Manager at GCT. “Being one of the slimmest connectors in class, it’s a great addition to the GCT Memory Card Connector range and offers our customers greater flexibility with their designs where having a low product height is critical.”

The requirement for smaller connectors remains strong, in the face of device miniaturisation and the quest to have lighter, slimmer and more compact electronics. The MEM2075 MicroSD connector is ideal for applications where space consideration is required, From portable electronics to wearable tech.

Modular Devices Introduces A New Line Of SSR’s!

Modular Devices introduces a new line of SSR’s for

lndustrial • Mil/Aero • Naval • Space

The trend in onboard electronic power systems is moving to higher voltage and power requirements across most systems. These include 270V and 540V Mil/Aero platforms, as well as Naval Surface and Subsurface and Space platforms. Recent developments in electric propulsion, directed energy, and photonic-based communications systems across these platforms require high voltage and high current switching with mission reliability.

The majority of commercially available DC SSRs use Silicon FETs and photovoltaic
opto-coupler drive circuitry, but these previously available devices have had two major performance draw backs :

• Higher contact voltage drop in the SSR’s compared to electro-mechanical relays. The higher voltage drop causes higher power dissipation and requires more efforts to cool the SSR to maintain usable junction temperatures.

• The disadvantages in the use of Photo-Voltaic (PV) opto-couplers to provide drive and isolation for the SSR’s are slow response time, limited drive power, and environmental limitations of this type of component.

MDI SOLUTION
Wide Band Gap Semiconductors
Wide Band Gap Semiconductors, such as GaN (Gallium Nitride) and SiC (Silicon Carbide) offer an order of magnitude improvement in DC SSR voltage drop over legacy Silicon-based power devices .

• High operating temperature, higher voltage capabilities, and lower ON resistance .
• Wide band gap semiconductors withstand higher electric fields with lower channel resistances and reduced drive requirements.

RF Coupled SSR Drive
RF Coupled SSR Drive replaces the PV function with a transformer-isolated RF drive and provides a faster, more temperature-stable
and temperature-resistant operation .

The magnetically isolated RF drive can be factory configured to operate from a wide range of control voltages from approximately 3.3 volts to
100 VDC and higher.

Mag Latch Drive
The magnetically isolated SSR can have a mag latch function, meaning it can be energized either by a continuous signal or by a short duration pulse. However, unlike an electromechanical relay, after removal of bias power the DC SSR reverts back to its initial state.

Certain models of the MDI DC SSR can be jumper configured for a latching relay function, or used without the latch .

The MDI SSR’s are packaged in a hermetically sealed case able to withstand severe environments. The units are available with and without mounting flanges.

EMI FILTERS MIL-STD 461C To MIL-STD-461D, E, F, G

MDI model *3678 Hybrid EMI Filters upgrade legacy converters with internal MIL-STD-461C CE03 EMI filters to meet the latest MIL-STD-461D,E,F,G test method

requirements.
MDI introduced the industry’s first hybrid DC-DC converters featuring built-in MIL-STD-461C CE03 EMI filters. 461C CE03 is a recognized EMI specification in widespread use that uses feed-through capacitors and a current probe to measure conducted emissions on power lines in dBμA units.

More recent test methods of MIL-STD-461D,E,F, G CE102 measure conducted emissions in voltage mode using a line impedance stabilization network referenced to a 50 ohm impedance in dBμV units. Also, after adjusting for a 34dB measurement differential, CE102 uses a newer slope-adjusted limit curve as compared to CE03. In the frequency range of 100-400kHz, where many hybrid DC-DC converters operate, the newer CE102 limits can be up to 24dB lower than corresponding CE03 limits.

MDI offers the model *3678, a compact standalone, low attenuation solution that permits users to meet newer MIL-STD-461D,E,F,G CE102 limits with legacy converters having built-in 461C CE03 filters.

The *3678 family of filters, sized to accommodate a broad range of popular satellite, ISS/Orion, airframe and vehcle input voltage buses, incorporate a common

mode stage and two low attenuation, low resonance differential mode stages.

The resulting design achieves the necessary attenuation for CE102 compliance while minimizing the possibility of excessive input filter impedance mismatch that

might otherwise result in DC-DC converter loop instability.

A single filter can serve several DC-DC converters up to the rated maximums and two or more *3678 filters may be used in parallel to serve multiple DC-DC

converters sharing the same input bus. Please see our application notes for insertion loss curves and full technical details.

MDI model *3727 MOAF (Mother Of All Filters) series meets the latest MIL-STD-461D,E,F,G CE102 test method requirements when used with most unfiltered DC – DC converters Now, MDI offers the model *3727 MOAF series, a compact standalone, low attenuation low I²R loss solution that permits users to meet newer MIL-STD-461D,E,F,G CE102 limits with legacy converters having built-in 461C CE03 filters.

They are particularly useful in power system applications where multiple DC-DC converters are paralleled in high load current and/or N+1 redundant applications.

The *3727 MOAFs, sized to accommodate a broad range of popular satellite, ISS/Orion, airframe and vehicle input voltage buses, incorporate two common mode stages and three low attenuation, low resonance differential mode stages.

The resulting design achieves the necessary attenuation for CE102 compliance while minimizing the possibility of excessive input filter impedance mismatch that might otherwise result in DC-DC converter loop instability .

Further, the design avoids use of multi-turn wound inductors, greatly reducing internal I²R copper losses, improving efficiency and reducing power dissipation.

A single MOAF can serve multiple DC-DC converters up to the published rated maximum current..
