Stackpole's AEC qualified RTAN series utilises tantalum nitride technology to provide moisture proof precision chip resistor performance. The RTAN film passes biased humidity testing at 85oC, 85% relative humidity, and ten percent bias with very little shift in resistance.

KOA Speer Electronics is adding a high power 0402 size to their SG73P series of anti-surge, pulse precision thick film chip resistors. The SG73P1EW has a power rating of 0.25W with a TCR as low as ±100ppm/°C. This represents a 100% increase in power compared to the existing SG73P 0402 package. The SG73P1EW provides greater power and precision in a 0402 package size. 

TTI has stock for immediate shipment of multiple values of the B41252 Series Snap-In Aluminum Electrolytic Capacitors from TDK/EPCOS.

Murata has extended its product offering for the mobile and High-Performance Computing (HPC) markets with the availability of its latest silicon process technology to fabricate silicon capacitors with a density of 1.3 µF/mm². 

As electronic devices continue to evolve, finding resistors that have higher power ratings in a given package size are more and more important. However, higher power resistors can often generate significantly more heat than resistors with standard power ratings.

Covering over 70% of the Earth’s surface, the oceans are a vital element of our planet’s ecosystem. However, for the millions of vessels that cross them, the aquatic environment can present a problem. Vessels are increasingly using electrical systems to power across oceans, but a component’s design must account for these extreme conditions. Here, David Atkins, project director at Cressall, investigates offshore resistor des...

High efficiency current sensing is commonly done using low resistance value resistors. However, as resistance values are reduced, the measurement error due to lead resistance becomes significant. For applications requiring high efficiency with the best possible temperature accuracy, four terminal metal element current sensing products are the ideal choice.

KEMET has announced announces its new C4AK high temperature, power film DC-Link film capacitor designed for continuous operation up to 1,000 hours at 135oC. The C4AK series joins the C4AU (harsh environment) and C4AQ-P (125°C) family of power DC-Link film capacitors.

AVX has released new UBC 550 Series ultra-broadband capacitors designed to deliver reliable, repeatable performance from 16KHz to 70+GHz in ultra-broadband microwave and millimeter-wave RF applications with stringent operating requirements.

Stackpole's RMCS series now offers a 2W power rating in a 2512 chip resistor size as the RMCS2512 ... -HP. This option doubles the standard 2512 power rating and allows for the RMCS-HP to be used for higher power applications that may have used a different technology previously.
