Radial leaded PolySwitch® resettable PPTC devices provide overcurrent protection to circuits, wiring harnesses, and printed circuit board components. Compact and suitable for soldering onto PCBs, these devices employ polymer positive coefficient temperature technology. This means the surface mount or inline devices rarely need replacing. Littelfuse makes several types of radial leaded PPTC devices for specific uses. For instance, our AEC-Q200-qualified devices are optimized for automized applications. Devices in our ARGF series offer ideal choices for protecting telecommunications equipment.
