CURRENT SENSING RESISTORS

The CS-227 is a metal foil, TO227 resistor designed to give a high current capability. The metal foil element issituated on an insulated heatsink composed of plated copper. This assembly is then mounted into a durableplastic housing and sealed with high temperature epoxy. This product features: Four terminals for precisecurrents, vibration proof, good insulation, compact size and easy bolt mounting.GENERAL SPECIFICATIONSModel Resistance Range[ & ] PowerRating [W] TCR[ppm/C] Tolerance[%] MaximumCurrent CS227A 1m, 2m, 5m 50 +-50 +-5 200A CS227B 2m+2m, 3m+3m 20 + 20 +-50 +-5 80A X 2 CHARACTERISTICS Values in [ ] mean change in ohmic value after testOperating Temp.
