Vishay Intertechnology, Inc. High Voltage Chip Divider in Molded Package Reduces Component Counts, Improves TC Tracking Performance

10/18/2021 | 11:00am
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 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 kO to 50 MO, 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.
