SRP120S Product Details

SRP120S Overview


PTC thermistors are packaged in the Bulk as a safety measure. Its terminations are 2. A PTC thermistor could provide 15V voltage when operating. A PTC thermistor is rated as 0.8W in terms of heat production. It is not recommended that PTC thermistors operate above 100A current. Temperatures should not exceed 85°C for thermistors. When the thermistor runs, the temperature should not drop below -40°C.
