Low Rho Series for Overcurrent and Overtemperature Protection

Littelfuse's Low Rho surface mount PPTC (polymer positive temperature coefficient) devices provide overcurrent protection for applications where ultra low internal resistance, ultra low voltage drop and automatic resettable protection are desired. This new series allows a higher hold current device in a smaller factor and lower profile as compared to a standard PPTC. It offers ultra low internal resistance while maintaining the high level electrical characteristics and performances of standard PPTC products. All devices are UL recognized and TUV approved and have maximum fault current of 50 A. They are available in 0402 to 2920 sizes while the hold current ranges from 100mA to 9A.
