VTP170XSF-3

Ptc Resettable Fuses Overview

The VTP170XSF-3 is a PolySwitch resettable fuse from the Littelfuse VTP series, designed for strap mount installation. It features axial termination and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a hold current of 1.7 A, trip current of 3.4 A, maximum voltage of 16 V, and maximum fault current (Imax) of 100 A. The device has a typical resistance of 52 mΩ, with dimensions of 17.5 mm in length and 0.8 mm in height.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection through self-resetting functionality upon cooling after fault clearance
• Utilizes strap mount design for secure mechanical attachment to PCBs or busbars
• Offers high fault current tolerance up to 100 A for robust overcurrent safeguarding

Ptc Resettable Fuses Applications

• LED assembly protection circuits
• DC/DC converter input/output lines
• Gate driver power supply protection

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix '-3' corresponds to the required packaging or tape-and-reel configuration as defined by Littelfuse documentation. Confirm that the axial lead style matches the target board layout requirements. Ensure the operating environment stays within the specified -40°C to +85°C range to maintain performance integrity.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile, strap-mount PTC device is required for 16 V systems. The 1.7 A hold current suits moderate load protection needs. Verify that the 52 mΩ resistance does not cause excessive voltage drop in the application. Consider the 100 A Imax rating against potential short-circuit scenarios.

Ptc Resettable Fuses Part Context

This part belongs to the VTP series of PolySwitch resettable fuses manufactured by Littelfuse. These components are engineered for circuit protection in consumer electronics and industrial applications. The VTP series emphasizes compact form factors and reliable re-tripping capabilities compared to traditional one-time fuses.

Ptc Resettable Fuses Replacement Considerations

VTP170XSF is the base model variant without the specific suffix. Cross-reference datasheets to confirm if the suffix indicates a packaging difference rather than an electrical change.
