A compact precision shunt resistor capable of handling high power loads. It is a metal foil resistor with a heat dissipation function (metal plate on the back) for high-precision current detection.
■Features■ ■A precision shunt resistor that is compact and capable of high power loads, thanks to carefully selected materials and a structure focused on thermal dissipation. ■Outstanding temperature characteristics and high load capacity. ■Standard delivery time: 60 days. ■Load capacity (continuous): 250W (chassis mounted)※1. ■Maximum continuous allowable current: 200A (pulse current 500A)※2. ■Standard resistance values: 1m, 2m, 5m, 10m, 20m, 50m, 100m, 200m, 500m, 1, 10, 100Ω. ■Tolerance: ±0.1%, ±1%. ■Temperature coefficient (20 to 60℃): ±1ppm/℃, ±3ppm/℃, ±5ppm/℃, ±10ppm/℃. ■Internal thermal resistance: 0.1℃/W. ※1 The resistance element has a maximum temperature limit of +125℃. Proper heat dissipation measures are required. (Please refer to this formula for selecting an appropriate heat sink.) ※2 This is for average power within 250W. ■For other functions and details, please download the catalog or contact us.
