VLP270XXUF

Ptc Resettable Fuses Overview

The Littelfuse VLP270XXUF is a PolySwitch resettable PTC device designed for strap mount applications. It features an axial end type and operates within a temperature range of -40°C to +70°C. The component maintains a holding current of 2.7 A and trips at 6.5 A, with a maximum voltage rating of 16 VDC. It offers a maximum fault current (Imax) of 60 A and exhibits a resistance of 18 mOhms. The 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 overcurrent protection through automatic reset functionality without manual intervention
• Features low internal resistance to minimize power loss during normal operation
• Designed for secure strap mounting using axial leads

Ptc Resettable Fuses Applications

• Overcurrent protection for automotive electronic circuits
• Protection of battery packs and charging systems
• Circuit safeguarding in industrial control modules

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'XXUF' against official Littelfuse documentation to confirm lead frame plating and tape-and-reel packaging specifications. Ensure that the required operating temperature range aligns with the component's rated limit of +70°C rather than higher-temperature variants. Confirm compliance requirements such as RoHS status prior to final procurement decisions.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile axial leaded PTC fuse is required for strap mounting on printed circuit boards. The 2.7 A holding current and 16 VDC rating make it suitable for low-voltage DC applications. Consider the 18 mOhms resistance value for thermal management calculations and ensure the 60 A Imax capability meets the prospective short-circuit current levels of the target circuit.

Ptc Resettable Fuses Part Context

This part belongs to the VLP series of PolySwitch resettable fuses manufactured by Littelfuse. These devices utilize polymer positive temperature coefficient technology to provide reliable circuit protection. The VLP series is engineered for high-volume manufacturing processes and offers consistent performance characteristics across various automotive and industrial environments.

Ptc Resettable Fuses Replacement Considerations

The VLP270F serves as a comparable alternative within the same family, though it utilizes a surface mount end type instead of axial leads. Verify mechanical fitment and mounting style compatibility before substituting. Electrical parameters such as holding current and voltage ratings should be cross-checked to ensure equivalent circuit protection capabilities.
