Low Resistance Resettable PTCs

Littelfuse Low Resistance Resettable PPTCs offer ultra-low normal operating resistance while maintaining the same performance of other Littelfuse PPTC products. The low resistance devices offer a 0.1A to 6A maximum current range, a 5V to 12V maximum voltage range, and overcurrent and over-temperature protections for various applications. The low-resistance resettable PPTCs are available in the Surface Mount Low Rho SMD Series, the Surface Mount LoRho Series, and the Battery Strap SL Series. The components are halogen-free, lead-free, and RoHS Compliant.
