VTP110F

Ptc Resettable Fuses Overview

The Littelfuse VTP110F is a PolySwitch resettable polymeric positive temperature coefficient (PPTC) device designed for battery strap applications. It features a maximum operating voltage of 16V and a hold current (Ih) of 1.1A. The component provides overcurrent protection with a trip current (It) of 2.7A and a maximum fault current rating (Imax) of 100A. It exhibits a typical time to trip of 5 seconds under specified conditions. The device is available in a strap package format, suitable for direct integration into battery management systems.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection against overcurrent conditions through self-resetting functionality
• Designed specifically for low-profile battery strap integration within electronic assemblies
• Ensures safety by interrupting high fault currents while maintaining low resistance during normal operation

Ptc Resettable Fuses Applications

• Battery pack protection in automotive electronics
• Portable electronic device power supply circuits
• Consumer electronics battery management systems

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix codes on the datasheet to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with RoHS standards and halogen-free requirements if mandated by the target application. Cross-reference the manufacturer's latest documentation to confirm active status and any potential design changes or obsolescence notices prior to final procurement decisions.

Ptc Resettable Fuses Selection Notes

Select this component when a low-voltage, high-current resettable fuse is required for battery strap applications. The 1.1A hold current and 16V rating define the operational envelope. Consider the physical strap form factor for PCB mounting constraints. Evaluate thermal dissipation requirements in enclosed spaces, as PPTC devices generate heat during tripping events. Confirm that the 100A Imax rating exceeds the maximum possible short-circuit current in the protected circuit.

Ptc Resettable Fuses Part Context

The VTP110F belongs to Littelfuse’s PolySwitch VTP series, which specializes in resettable fuses for battery applications. This series emphasizes low profile and robust performance for protecting lithium-ion and other battery types. The VTP line is engineered to meet stringent automotive and industrial reliability standards, offering a compact alternative to traditional one-time fuses in space-constrained designs.

Ptc Resettable Fuses Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Generic PTC replacements may differ in trip characteristics or physical dimensions. Do not assume interchangeability without verifying voltage, current ratings, and package compatibility against the original design specifications.
