1210L050 Product Details

1210L050 Overview


It is recommended to set the minimum operating temperature of the PTC thermistors at -40°C. Ensure this thermistor is working at 85°C by keeping its operating temperature below that. PTC thermistors are terminated at 2. As a result, PTC thermistors may supply 13.2V voltage at all times. Thermal resistance should be 600mW when PTC thermistors are used. A PTC thermistor should not have a current higher than 100A.
