1210L450SL - Resettable PTCs

Download the 1210L450SL datasheet PDF. This datasheet also covers the 1210L175SL variant, as both devices belong to the same resettable ptcs family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key 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.
  • 0402 size available - the smallest PPTC in the market.
  • Compatible with high temperature solders.
  • Broadest range of Hold Current ratings (100mA to 9A).
  • RoHS compliant, Lead Free and Halogen Fr.

Low Rho Surface Mount Series POLY-FUSE® Resettable PTCs Surface Mount > Low Rho Series RoHS Agency Approvals Agency Agency File Number E183209 R50119118 Description 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.
