B57238S509M Overview
I have included it in package Radial for convenience. A maximum operating temperature of 170°C ensures that NTC thermistors can operate reliably. Optimal reliability requires a minimum temperature of -55°C for NTC thermistors. A total of 2 terminations are provided on these NTC thermistors. The 2 pins of the NTC thermistor must be connected in order for it to function properly. If the NTC thermistors are operated at the maximum current, the fuse element will not be adversely affected. A NTC thermistor should have a supply voltage of 265V for maximum efficiency.
