Three series of miniature infrared (IR) receiver modules for IR remote control applications have been released by Vishay Intertechnology. Devices in the Vishay Semiconductors TSOP93xxx, TSOP94xxx, and TSOP98xxx series deliver improved dark-ambient and disturbed-ambient sensitivity to infrared signals, better suppression of RF noise, and excellent pulse-width accuracy.

  Two years ago at electronica, Ohmite launched their first ceramic heatsink and a prototype resistor using the same material, this year they will have a complete range to talk to customers about following this week’s acquisition of the electronic components business of Kanthal, a part of Sandvik Group.

With the BVF precision resistor, Isabellenhütte Heusler has developed a precision resistor that not only impresses with its overall size 1213 (3.1x3.3mm), but also with its high load capacity and precision in use. Smaller electrically-operated applications in particular benefit from the properties of the high-performance component that Isabellenhütte has now included in its series repertoire.

A range of ruggedly constructed, ultraminiature (EIA 0402, 1005 metric) equalisers has been launched by AVX Corporation, with the GEQ Series RC equalisers. These combine high-performance tantalum nitride (TaN) resistive elements and silicon/oxygen/nitrogen (SiON) capacitive elements with AVX’s proprietary, automotive-qualified, glass-sandwich FLEXITERM surface-mount technology.

  Skeleton Technologies and Wrights Group have signed a high volume, multi-million euro contract over the next five years. Skeleton Technologies supplies graphene-based ultracapacitors to the latest KERS enabled hybrid-electric double and single deck buses produced by the Wrights Group.

Stackpole is now stocking the MLFA AEC compliant metal film melf resistors. The MLFA is available in a 0.4W rated 0204 size in the MLFA25 and a 1W rated 0207 size in the MLFA1. The MLFA has exceptional stability demonstrated over life, biased humidity, and short time overload testing. In addition, the MLFA offers pulse power handling up to 3500 watts for single short duration pulses, and lightning surge withstanding up to 6KV for resistance value...

Stackpole is now stocking the most popular sizes and resistance values of its HVA Series. The HVA Series offers high voltage handling up to 8000V in a small package size. The RoHS compliant and halogen free HVA Series offers resistance values from 1M up to 1G in tolerances as low as 1% and in 200ppm TCR. The high voltage film achieves VCR of 20ppm/V or better.

Automotive is one of the strongest growing markets for electronic components worldwide. AEC-Q200 compliant components are consistently being designed into automotive systems such as EV power train and battery management, infotainment, engine control, air bags, lighting and more. The demand for ‘off-the-shelf', yet highly rugged devices is expanding fast, and in many cases outstripping supply.

A series of ultra-low profile high power resistors has been introduced by TT Electronics. The WDBR-UL resistors are based on the existing WDBR product which has been successfully used in the field for over ten years. The WDBR-UL series’ creepage, clearances and power ratings have been assessed in accordance with the requirements of UL508, easing the compliance burden for UL approved end users.
