PT Series Low TCR Current Sensor Resistors Yageo PT Series Low TCR Current Sensor Resistors are AEC-Q200 qualified, low TCR, and high power with lead-free terminations made by a thick film process. These resistors feature high component and equipment reliability and low resistances applied to current sensing. The PT series resistors are constructed out of a high-grade ceramic body. These surface mount resistors operate at -55°C to 155°C temperature range. The PT Series resistors are RoHS compliant, Halogen-free, and MSL Level 1 rated. These resistors are suitable for converters, printer equipment, server board, telecom, consumer, and car electronics.
