ABOUT CSM (Low Ohm Value 1 mΩ to 200 mΩ)

New high-precision Bulk Metal® surface-mount Power Metal Strip® resistor of 1 mΩ to 200 mΩ that features an improved load-life stability of ± 0.2 % at + 70 °C for 2000 h at rated power, an absolute TCR of ± 15 ppm/°C maximum from - 55 °C to + 125 °C, + 25 °C ref., and a tolerance of ± 0.1 %.
Typical current sensing resistors offer a load-life stability of ≥ 1 % through a 2000 h workload. The improved resistance stability of the CSM Series makes it ideal for tightened-stability voltage division and precision current sensing applications in switching linear power supplies, power amplifiers, measurement instrumentation, bridge networks, and medical and test equipment. In addition, the CSM Series complies with EEE-INST-002 (MIL-PRF 55342 and MIL-PRF 49465) for military and space applications.
