16VT210LU

Ptc Resettable Fuses Overview

The Littelfuse Inc. 16VT210LU is a polymeric PTC resettable fuse from the POLY-FUSE VT series, designed for circuit protection in electronic systems. It features a maximum voltage rating of 16V and a hold current (Ih) of 2.1A. The device trips at 4.7A with a maximum trip time of 5 seconds. Initial resistance is typically 18 mOhms, rising to a maximum of 60 mOhms after tripping. It supports a maximum fault current of 100A and operates within a temperature range of -40°C to +85°C. The component utilizes a strap package style for user-defined mounting.

Ptc Resettable Fuses Feature Summary

• Polymer-based self-resetting mechanism provides reusable overcurrent protection without manual replacement.
• Strap-style physical configuration allows flexible integration into custom PCB layouts or harnesses.
• Integrated thermal-magnetic response ensures reliable circuit interruption during sustained overload conditions.

Ptc Resettable Fuses Applications

• Portable consumer electronics requiring compact overcurrent protection
• Battery-powered devices needing reusable safety components
• Industrial control circuits with defined voltage limits

Ptc Resettable Fuses Procurement Notes

Verify component availability status as this part is listed as obsolete. Confirm that the strap mounting style aligns with specific assembly requirements. Ensure design parameters remain within the 16V and 2.1A limits. Check for RoHS3 compliance documentation if required for regulatory standards. Validate that the 100A maximum current rating exceeds expected fault scenarios.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile, strap-mounted PTC fuse is required for 16V systems. The 2.1A hold current suits moderate load applications. Consider the 18 mOhms initial resistance for minimal voltage drop impact. Evaluate the 5-second trip time against system tolerance for transient surges. Ensure the -40°C to +85°C operating range covers environmental conditions.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse POLY-FUSE VT series, which focuses on polymer positive temperature coefficient resettable fuses. The series offers various current ratings and package styles. The 16VT210LU specifically addresses needs for strap-type mounting solutions in space-constrained designs.

Ptc Resettable Fuses Replacement Considerations

No public confirmed substitute part numbers are available for this obsolete component. Designers should consult Littelfuse for current equivalent series recommendations or perform full re-qualification if selecting alternative PTC fuses with similar electrical characteristics.
