Lo Rho Series Low Resistance SMD PPTCs

 

Littelfuse Polyfuse® resettable PPTCs with ultra low operating resistance


PPTC (polymer positive temperature coefficient) fuses limit unsafe currents while allowing constant safe current levels. They can automatically reset when the current and temperature return to safe levels. The Littelfuse SL Series of Lo Rho PPTCs further minimize power consumption during operation, making them ideal for applications where minimum power consumptions and miniaturization are critical.   Datasheet Lo Rho Series Low Resistance SMD PPTCs
