Foil Resistors CSM High Precision Resistors Vishay Precision Group/Foil Resistors CSM Series Resistors offer Bulk Metal® Technology and high precision. The surface mount CSM Series Resistors from Vishay Precision Group/Foil Resistors have a resistance range of 1mΩ to 200mΩ, resistance tolerance of ±0.1%, rated power up to 3W, maximum current up to 54A, and maximum temperature coefficient of resistance (TCR) of ±15ppm/ºC (-55ºC to +125ºC, +25ºC ref.) In addition, when compared to typical current sense resistors, CSM series resistors offer an improved load-life stability of ±0.2% at +70ºC for 2000 hours at rated power as opposed to the ≥1% per 2000 hour workload offered by other current sense resistors. As a result, CSM series resistors are 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.
