Vishay Introduces Molded Packaged High Voltage Chip Resistor Dividers to Reduce Component Count and Improve TC Tracking Performance

     Vishay Intertechnology, Inc. announces the launch of the industry's leading high voltage chip resistor divider, CDMM, in a standard surface mount molded package. Vishay Techno CDMM resistance divider with 4527 dimensions and maximum operating voltage up to 1500 V, reduces the number of components, improves TC tracking performance and proportional stability, suitable for automotive and industrial equipment.

     The recently released chip resistor divider integrates two resistors in a single molded package. One such device can replace several discrete resistors in voltage divider applications. New space-saving, AEC-Q200 qualified resistor dividers for electric vehicles, heavy industrial equipment, and bus high-power DC/DC converters and inverters.

     CDMMs are available in resistance values from 500 kW to 50 MW, with a maximum resistance ratio of 500:1 and a tolerance of ± 0.5 %. This chip resistor divider is sulfur tolerant, RoHS compliant, halogen free, has a temperature coefficient of ±100 ppm/°C (not in the datasheet), and TCR tracking down to ±10 ppm/°C. The device complies with IEC 60664-1 with a creepage distance of 12.5 mm and a rated working voltage of 1250 V.
