TRF250-180U Product Details

TRF250-180U Overview


In order to ensure the safety of these PTC thermistors, they are packaged in Bulk. Setting the minimum operating temperature of PTC thermistors to -40°C is recommended. If this thermistor is to work correctly, it must operate at 85°C. PTC thermistor terminations are 2. While operating, the PTC thermistors could output 100V voltage. The PTC thermistors are designed for 10A current. A DC circuit uses 100V to rate these thermistors. PTC thermistors should produce 1.5W heat. PTC thermistors should not have a higher current than 10A.
