Passives

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.

New from Aerco is an extension of the popular range of remote controlled, load disconnecting relays from E-T-A that provides both electronic relay and electronic over-current protection in a single unit.

Cherry Electrical Products is releasing its new miniature square rocker switch. Measuring in at just under 20 mm x 13 mm, the device features 10 or 20A switching, and offers single or double-throw options, as well as a choice of actuator and housing colour. A variety of terminals is available, with industry-standard mounting dimensions. The mechanical life of the parts extends to a minimum of 100,000 operations

Lorlin Electronics has announced the its new MDSP push button switch. The UK manufactured MDSP is a push-on, push-off switch with a potentiometer mounted on the same spindle and will find wide acceptance in many industrial and professional switching and control applications.
