AVX – Film resistors optimized for maximum power handling and low VSWR (BeO-free -Resistors)

Jun 19 2012 - Passives [More Passives Articles]

A series of thin and thick film resistive products, optimized for maximum power handling and low voltage standing wave ratio (VSWR) applications, has been developed by AVX. The series, which includes high-power resistors, terminations, and attenuators, features power handling from 4W to 800W, and is available in a variety of sizes and termination styles, including flange, leaded, and surface mount.

Processed using thin-film (sputter) technology to guarantee consistent quality, AVX’s new, high-power resistive product series is ideal for markets with several high-power and high frequency applications, including wireless infrastructure and telecommunications, broadcasting, medical diagnostic, semiconductor manufacturing, military and aerospace equipment.

“AVX’s high-power rated resistive products have been tested and manufactured to ensure consistent performance, reliability, and durability,” said Chris Reynolds, product manager, AVX. “Built to exceed customers’ expectations, our new resistive products are well-suited to a broad range of applications including dummy loads, matching units and improving isolation between ports in power divider and combiner designs, improving power handling and powering VSWR in couplers, and saving space with improved matching and power dissipation in microwave integrated circuits (MIC).”

The resistors in the series provide consistent values ranging from 10ohm to 200ohm (standard is 50ohm and 100ohm; consult AVX for higher resistance custom designs). Additionally, the series includes several BeO-free resistors, terminations, and attenuators, which feature advanced 100% thin film process, aluminum nitride substrates and a power rating of 4W to 250W.

The new, high-power resistive product series has undergone rigorous product qualification testing (per MIL PRF55342) and is ROHS compliant, says the company.
