Ultra-Small 0603 PPTC Resettable Overcurrent Protection

Littelfuse's 0603L surface mount PPTC (polymer positive temperature coefficient thermistor) series offers ultra-small size and is resettable

Image of Littelfuse's Ultra-Small 0603 PPTC Resettable Overcurrent Protection Littelfuse is pleased to introduce the 0603L surface mount PPTC (polymer positive temperature coefficient thermistor) series, the newest and smallest edition to the Littelfuse Polyfuse® PTC line. Available in 4 hold current ranges 0.10 A, 0.20 A, 0.25 A, and 0.35 A, each device is certified by both TUV and UL and possess a maximum fault current rating of 40 A.

Similar to traditional fuses though automatically resettable, PPTCs provide overcurrent protection of sensitive electronics. PPTCs increase resistance as temperature increases due to increased current flow. They limit unsafe currents while allowing constant safe current levels, and reset when the current and temperature returns to a safe level. PPTCs are typically used in sensitive electronic applications where frequent over-current conditions can occur, constant system uptime is required, and automatic resetting desired. With its ultra-small size and resetability, the 0603L series is ideal where miniaturization is desired, space is limited, and limited accessibility (due to size or location) is a factor.
