B59990C80A70 Product Details

B59990C80A70 Overview


Into Radial packages, PTC thermistors are put to prevent damage. Setting the minimum operating temperature of PTC thermistors to -40°C is recommended. If this thermistor is to work correctly, it must operate at 125°C. It has 2 pins. While operating, the PTC thermistors could output 80V voltage. This thermistor can supply 63V nominally when in operation. The PTC thermistors are designed for 30mA current. PTC thermistors should not have a higher current than 700mA.
