B59870C120A70 Product Details

B59870C120A70 Overview


Keeping PTC thermistors in Radial packages prevents them from being damaged. Ensure that the PTC thermistors are set to -40°C as their minimum operating temperature. In order for this thermistor to work properly, the operating temperature must not exceed 125°C. PTC thermistors have terminations of 2. A thermistor like this has 2 pins. When operating, PTC thermistors could deliver a voltage of 265V. In order to design PTC thermistors for 1A current, they must have a negative voltage. Ildeally, PTC thermistors should operate at no more than 1A current. A reliable performance can be achieved by using a thermistor that supplies a maximum voltage of 265V.
