Vishay's new high-voltage chip divider improves TC tracking performance

Vishay Intertechnology has introduced the industry’s first high-voltage chip divider to be offered in a ribbed, molded package with compliant surface-mount leads.

Designed to reduce component counts and improve TC tracking performance and ratio stability in automotive and industrial equipment, the Vishay Techno CDMM delivers a maximum working voltage of 1500 V in the 4527 case size.

Consisting of two resistors integrated into one molded package, the chip divider released today provides a single-component replacement for multiple discrete resistors used in voltage divider applications.

The space-saving, AEC-Q200 qualified device is optimized for high-power DC/DC converters and inverters in electric automobiles and heavy industrial equipment and buses.

The CDMM offers a wide resistance range from 500 kW to 50 MW, with maximum resistance ratios to 500:1 and tolerances down to ± 0.5 %. Sulfur-resistant, RoHS-compliant, and halogen-free, the chip divider features a temperature coefficient of ± 100 ppm/° C (not in datasheet) and TCR tracking as low as ± 10 ppm/° C.

Compliant with IEC 60664-1, the device offers a 12,5 mm creepage distance and is rated at 1250 V.

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