Lo Rho Series

Littelfuse LoRho™ 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 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™

SMD PPTC is the smallest size surface mounted PPTC

device available in the market.
