Passives

The new PPC Series 1mm-thin aluminium polymer capacitors from Cornell Dubilier are in stock at TTI Europe.

A new series of miniature snap-in power aluminium electrolytic capacitors that enables higher power density designs has been introduced by Vishay Intertechnology.

Murata Manufacturing says it has succeeded in commercialising the world's smallest*1 PTC thermistor*2 (commonly known as a resettable fuse*3) in the 0201 inch size (0.6×0.3×0.3mm) for mobile devices, and has recently begun mass production of this device under the part number PRG03BC181QB6RL.

TTI is now offering Panasonic’s 1,100Vdc series that has been added to the existing 630Vdc ECWFG Series Metallised Polypropylene Film Capacitors.

Panasonic Industry Europe has added the FN series, a low ESR Aluminum Electrolytic capacitors Surface Mount type, to its product line-up. Available from a rated voltage of 6.3VDC to 100VDC, the FN series offers wide capacitance values (10µF up to 1800µF), which are between 20% and 80% higher than the long-running FK series.

If active components are the attention-grabbing rock stars of the component world, then passives are the backstage team: just as important, but getting on with their job quietly in the background.

Pasternack has just released a new line of waveguide shorts and shims that are well suited for use in satellite communication, radar, wireless communication, and test and instrumentation applications.

Vishay Intertechnology has announced that the company has extended its TNPU e3 series of Automotive Grade ultra precision thin film flat chip resistors with a new space-saving component in the compact 0402 case size.

There is an on-going trend to smaller, portable and more functional devices in the consumer electronics world. This is particularly true in the current sense chip resistor market where power control architectures are being downsized even as the functionality is being enhanced.

Low resistance values are important for high efficiency current sensing in that lower values mean less wasted power on the current sensing measurement itself. But sensing low resistance values becomes challenging because of lead resistance. Using a four terminal shunt resistor eliminates the detrimental effects of lead resistance on the current sensing measurement operation.
