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 and TUV recognized
and have maximum fault current of 50A. They are
available in 0402 to 2920 sizes while the hold current
ranges from 100mA to 7A. Littelfuse 0402 size LoRho™
