MF-USMF050 Product Details

MF-USMF050 Overview


A Cut Tape is used for the safety of these PTC thermistors. A minimum operating temperature of -40°C should be set for the PTC thermistors. It is important that this thermistor does not operate at a temperature above 85°C. A PTC thermistor has a termination of 2. When the PTC thermistors operate, they supply 13.2V. thermistors in the DC circuit are rated at 13.2V volts. The heat produced by PTC thermistors should be 600mW. There should be no current over 40A for PTC thermistors.
