This specification covers the CUM1206, CUM2512, CUM2725, CUM2728, and CUM4527 series of high power current sensing resistors. These resistors are designed for applications including current sensing, voltage division, and pulse applications, with a particular suitability for high-precision current sensing and circuit protection. They feature stable alloy materials offering ultra-low TCR ( 50ppm/C), and are constructed with stabilized materials that allow for high temperature derating up to +170C. Pure tin plating ensures compatibility with both lead-free and lead-containing soldering processes. These resistors exhibit excellent stability with a low change in resistance (|R/R| 1.0% for 1000 h at 70 C) under various environmental conditions. They are compliant with RoHS directive 2011/65/EU and Halogen-free, and utilize flame-retardant material meeting UL94 V-0 requirements.
