1812L075-C Product Details

1812L075-C Overview


For protection, PTC thermistors are packaged in 1812 packages. Using PTC thermistors at -40°C temperature should be their minimum operating temperature. There must not be an increase in temperature above 85°C for this thermistor to work. PTC thermometers have 2 terminations. A PTC thermistor could supply 13.2V voltage when it is in operation. PTC thermistors have been designed to operate at 100A volts. In order to avoid overheating, PTC thermistors should be kept at a 100A current.
