Vishay Resistors Reduce Component Counts, Improve Accuracy

For Automotive and Industrial Applications, Space-Saving Devices Offer Maximum Working Voltage of 1415 V in Compact 2512 Case Size


MALVERN, Pa.— Vishay has introduced a new series of Automotive Grade thick film chip resistors in the compact 2512 case size with high working voltages up to 1415 V. The Vishay Techno CDMA series devices are designed to lower component counts and placement costs for automotive and industrial applications. Further, reducing PCB sizes and providing increased accuracy and stability.

It consisting of two resistors integrated into a single package with a 5 mm creepage distance. The chip resistors released provide single-component replacements for multiple discrete resistors used in voltage divider applications. The space-saving, AEC-Q200 qualified devices are optimized for voltage monitoring and overvoltage protection. They are applicable in high power DC/DC converters and inverters, on-board chargers, and battery management systems.

The CDMA series offers a wide resistance range from 500 kΩ to 50 MΩ, with maximum standard resistance ratios to 600:1. Further, it has tolerances down to ± 0.5 %, and TCR tracking as low as ± 10 ppm/°C. RoHS-compliant and halogen-free, the chip dividers feature a 3-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.
