PRF21BB471QB1RA Overview
The PTC thermistors are put into 0805 packages to protect the devices from damage. For PTC thermistors, -20°C should be the minimum operating temperature. The operating temperature of this thermistor must not exceed 130°C. PTC thermistor terminations are 2. A thermistor has a pin count of 2. During operation, PTC thermistors could supply 32V voltage. In theory, this thermistor can deliver 32V when it is in operation. For the PTC thermistors, the current requirement is 100μA.
