Automotive-grade thick film chip resistors designed by Vishay improve stability

Designed to reduce component count in automotive and industrial applications, the Vishay Techno CDMA series of automotive-grade thick film chip resistors are supplied in a compact 2515 case with working voltages up to 1415V.

They are designed to lower component counts and placement costs while reducing PCB sizes and providing increased accuracy and stability, added the company. 

Each consists of two resistors integrated into a single package with a 5.0mm creepage distance. The chip dividers provide single-component replacements for multiple discrete resistors used in voltage divider applications. The AEC-Q200 -qualified devices are optimised for voltage monitoring and over-voltage protection in high power DC/DC converters and inverters, on-board chargers and battery management systems in electric vehicles (EV) and industrial equipment. 

The CDMA series offers a wide resistance range from 500 kOhm to 50 MOhm, with maximum standard resistance ratios to 600:1, tolerances down to ± 0.5 per cent and TCR tracking as low as ± 10 ppm per degree C. The chip dividers are RoHS-compliant and halogen-free. They have a three-sided wraparound termination configuration, with solder-coated nickel barrier terminations standard. 

Samples and production quantities of the CDMA series devices are available now, with lead times of 14 weeks. 

Vishay manufactures one of the world’s largest portfolios of discrete semiconductors and passive electronic components for use in the automotive, industrial, computing, consumer, telecommunications, military, aerospace, and medical markets.
