Precision chip resistors with tolerances of 0.1% or tighter and TCR of 25 ppm or better have become more common due to the wide range of applications and end products requiring such resistors. However, some of these applications require circuit operation in high humidity environments.

New Yorker Electronics has announced the global distribution of the newly expanded line of Heat Sink Extrusions from Advanced Thermal Solutions (ATS).

New Yorker Electronics is distributing the newest Exxelia Sic Safco Long-Life Aluminium Electrolytic Capacitor.  

KEMET's KC-LINK with KONNEKT technology surface mount capacitors are designed for high-efficiency and high-density power applications. They are in stock at distributor Digi-Key.

Here, Damiano Natali, research and development engineer at power resistor manufacturer Cressall, explains how Computational Fluid Dynamics (CFD) improves product designs that have stayed much the same for decades.

Panasonic Industry Europe has introduced the new surface-mount type ZF series of Conductive Polymer Hybrid Aluminium Electrolytic Capacitors. Being able to endure high temperatures of 150°C for up to 1.000 hours, the new capacitors benefit from a high withstand voltage of 25 to 63V and a low leakage current of (0.01 CV or 3µA). The nominal capacitance range is 33 to 270µF.

Panasonic's ERJ-UP3 series of anti-sulphureted thick-film chip resistors, anti-surge type come in an 0603-inch case size.

Applications requiring power control and monitoring are becoming more demanding. High power sensing with low TCR and low thermal resistance are important when power electronics have size constraints.

Applications requiring power control and monitoring are becoming more demanding. Specifically, added functionality and higher power requirements require higher efficiency, high accuracy, and higher power handling. Stackpole’s five watt current sense chip resistor could be the solution.

The new VPG Foil Resistors Model 303337 ultra-high precision military-and space-grade resistor is on sale at New Yorker Electronics.
