Product Description
Product Overview
The ISA-PLAN VMP series from Isabellenhtte are high-precision current sense resistors designed for demanding power hybrid applications. These 2010-sized resistors offer a 2 W power rating at 110 C and can handle constant currents up to 20 A with a low resistance value of 5 mOhm. They are engineered for excellent long-term stability, high pulse power capability, and feature AEC-Q200 qualification. Suitable for control systems in the automotive market, power modules, frequency converters, and switch mode power supplies, the VMP resistors are compatible with reflow and IR soldering processes.
