Littelfuse 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 50A. They are available in 0402 to 2920 sizes while the hold current ranges from 100mA to 9A.

Features:

Ultra low internal resistance
Very thin profile
Miniature size saves board space
Allows a higher hold current dvice in a smaller factor and lower profile as compared to a standard PPTC
Fast response to fault currents
Compatible with high temperature solders
Broadest range of Hold Current ratings (100mA to 9A)
RoHS compliant, Lead Free and Halogen Free
UL recognized and TUV approved

Applications:

USB peripherals including new USB 3.0 / 2.0 ports
Li-ion / Li-Polymer battery pack
Smart phones
Tablet and Notebook PCs
E-readers
LCD / LED HDTV
Computer periperals
Digital cameras and video cameras
Hard disk drives
Game consoles
