Focus EDL’s appointment by leading discretes manufacturer EIC gives its customers access to what is recognized as the industry’s widest range of transient voltage suppressors (TVS). With the trend towards lower voltages and higher integration, particularly in MOS devices and low power ICs, TVS devices are increasingly necessary for protection against over-voltage situations. They are used in a wide variety of applications such as power suppl...

Cherry Electrical Products has announced its new DH ultraminiature switch. Measuring just 8.2 x 2.7 x 6.2 mm these devices offer a maximum switching voltage of 30VDC and a maximum switched current between 300 and 500mADC, depending on model. With a mechanical life of over 50,000 operations, parts operate between -25 and +70degC.

Schurter has announced today the addition of a new mounting technology to its range of metal switches. The switches are assembled from the front side of the equipment and then force fitted into the front panel. Thus, these new metallic switches with snap in technology enable quick and efficient assembly in buildings, controllers or equipment with limited or no access from the rear. Such applications include hollow sections used in buildings or eq...

The latest addition to Schurter’s range of RoHS compliant products is the UMT 250 fuse-link. The UMT 250 offers the highest protection currently available in primary protection SM fuses, touting a breaking capacity rating of 200 Amps at 250 VAC or 100 Amps at 125 VDC over a current range of 315 mA to 4 A.

AVX’s 1210 B case size TCJ series of polymer tantalum capacitors launched last year is now available with even lower ESR, reduced from 70 to 45mΩ. For the design engineer this means lower output noise and improved ripple current in their circuits. It also means, faster pulse energy in key areas of the circuit, which has become much more important with the increased usage of battery power for handheld equipment.

AVX is extending its range of high voltage Multi Layer Ceramic Chips to include an industry standard voltage option of 630V. The passives specialist’s new 630V range offers high capacitance values, low leakage and small size, parameters often difficult to obtain for high voltage systems.

knitter-switch has announced two miniature, multi-function tact switches that will find wide application in portable electronic devices including handheld instruments and PDAs. The TSSJ4 and TSSJ5 are both joystick style switches designed for surface mounting and manufactured to provide a minimum of 100,000 cycles.

Murata has announced a number of recent additions to its LLL, LLA, LLM and LLK series of low ESL capacitors, extending the capacitance ranges, over standard and extra low profile versions, while keeping ESL especially low. The LLL range, for example, with ESL quoted at 150 to 250pH, and targeting microprocessor clock speeds from 120 to 800MHz, has been extended with a number of X7S dielectric parts with capacitance ranges now up to 0.68µF (low ...

Following its appointment by EIC Semi Ltd, the leading discrete components manufacturer, Focus EDL has made available a very wide range of Zener Diodes covering Zener voltages up to 200V and power up to 5W. Zener diodes are used in power conversion and protection solutions for industrial, automotive, and consumer applications.
