Vishay Intertechnology, Inc. 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 kΩ to 50 MΩ, 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.
