Thick film chip resistors cut component count, PCB size

A new series of AEC-Q200 qualified high voltage thick film chip resistors has been introduced by Vishay Intertechnology.

Offering working voltages to 3000 V, stability of 1.0 %, and power ratings up to 1.0 W, the Vishay Techno CRHA series is available in five compact case sizes ranging from 1206 to 2512.

With their high voltage handling capability — combined with better accuracy and stability than most standard thick film chip resistors — the Automotive Grade devices released today enable designers to reduce component counts, placement costs, and PCB size.

The resistors offer a wide resistance range from 2 MΩ to 500 MΩ, tolerances down to ± 1.0 %, and temperature coefficients of ± 100 ppm/°C.

These specifications make the devices ideal for battery management and voltage monitoring, division, and regulation in power inverters and high voltage power supplies for automotive, industrial, and medical applications.

CRHA series resistors feature solder-coated nickel barrier terminations in a three-sided wraparound configuration.

The devices are RoHS-compliant with exemption, and halogen-free.
