B59755C0115A070 Description

The B59755C0115A070 is a PTC thermistor for overcurrent, protection and as inrush current limiters. To prevent gradual component damage and to prevent blowing fuses or tripping circuit breakers, an inrush current limiter is a component that limits inrush current. Inrush current is frequently reduced by using fixed resistors and thermistors with negative temperature coefficients (NTC).
