CDMM High Voltage Chip Divider Series
CDMM High Voltage Chip Divider Series

Vishay Intertechnology has introduced a high voltage chip divider that is designed to reduce component counts and improve TC tracking performance and ratio stability in automotive and industrial equipment. This new CDMM Series offered in a ribbed molded package with compliant surface-mount leads delivers a maximum working voltage of 1500 V in the 4527-case size and provides a single-component replacement for multiple discrete resistors used in voltage divider applications. This AEC-Q200 qualified device is optimized for high-power DC/DC converters and inverters in electric automobiles and heavy industrial equipment and buses.


Consisting of two resistors integrated into one molded package, this new chip divider offers a wide resistance range from 500 kW to 50 MW, with maximum resistance ratios to 500:1 and tolerances down to ± 0.5%. Compliant with IEC 60664-1, this device features a temperature coefficient of ± 100 ppm/°C and TCR tracking of ± 10 ppm/°C.



  • High voltage up to 1500V utilizing thick film technology

  • Precision to ± 0.5% with low TCR tracking to 10ppm/°C utilizing thick film technology

  • Sulfur resistant

  • Automotive compliant terminations

  • AEC-Q200 qualified

  • Wide range of resistance value and ratios

  • 12.5mm creepage distance. Rated 1250V per IEC 60664-1



  • DC/DC converters

  • Electric automobiles

  • Industrial equipment



Samples and production quantities of the CDMM series are now available with lead times of stock to 12 weeks.
