VTP210F

Ptc Resettable Fuses Overview

The Littelfuse VTP210F is a PolySwitch resettable PPTC device designed for strap mount installation. It features a hold current of 2.1 A and a trip current of 4.7 A, with a maximum voltage rating of 16 VDC. The component has a maximum interrupting rating (Imax) of 100 A and a typical resistance of 60 mOhms. It operates within a temperature range of -40°C to +85°C and dissipates up to 1.2 W. Physical dimensions are 23.1 mm in length, 5.3 mm in width, and 0.8 mm in height.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection against overcurrent conditions through positive temperature coefficient behavior
• Designed for strap mount installation using SMD/SMT termination types
• Offers high fault current interruption capability for robust circuit safeguarding

Ptc Resettable Fuses Applications

• Overcurrent protection in electronic circuits requiring resettable fuse functionality
• Protection of low-voltage DC power lines operating at or below 16 VDC
• Industrial and consumer electronics applications subject to ambient temperatures between -40°C and +85°C

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix designation when ordering, as variations such as 'SF' may indicate different packaging or material specifications compared to the base model. Confirm that the required hold current and voltage ratings align with the system design constraints before procurement. Ensure compatibility with strap mount installation methods and verify RoHS compliance status if required by the end product regulations.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable overcurrent protection solution is needed for low-voltage applications. The 2.1 A hold current suits circuits with steady-state loads near this value. Consider the 16 VDC maximum voltage limit and the 100 A interrupting rating to ensure adequate safety margins. Verify that the physical dimensions fit the available board space and that the operating temperature range meets environmental requirements.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse VTP series of PolySwitch resettable fuses. These devices utilize polymer technology to provide reusable overcurrent protection. The series is characterized by its ability to automatically reset after cooling down following a fault event, eliminating the need for manual replacement associated with traditional fuses.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other VTP series parts for similar electrical characteristics. Verify that any substitute maintains the same hold current, voltage rating, and package mounting style to ensure functional equivalence in the existing circuit design.
