LVR016S

Ptc Resettable Fuses Overview

The Littelfuse LVR016S is a PolySwitch radial-leaded resettable PPTC fuse designed for line-voltage-rated circuit protection. It features a hold current of 160 mA and a trip current of 370 mA, with a maximum voltage rating of 120 VAC/VDC. The device has a maximum fault current rating of 20 A and an initial resistance of 7.8 Ohms. Operating within a temperature range of -40°C to +85°C, it dissipates up to 1.4 W. Physical dimensions include a diameter of 9.9 mm and length of 3.8 mm, with a lead spacing of 5.8 mm.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection by raising resistance as it heats to limit current flow during fault conditions.
• Offers automatic reset functionality after cooling, eliminating the need for manual replacement compared to traditional fuses.
• Designed for PCB mounting with radial leads, ensuring secure installation in compact electronic assemblies.

Ptc Resettable Fuses Applications

• Protection of telephony and networking equipment from high-voltage fault currents.
• Overcurrent safeguarding for automotive actuators, screens, and small motors.
• Circuit and wiring harness protection in consumer electronics and power supply applications.

Ptc Resettable Fuses Procurement Notes

Verify the specific manufacturer part number against official Littelfuse documentation to ensure compatibility with design requirements. Confirm that the radial lead configuration and physical dimensions align with the target PCB layout. Check for any recent product change notifications or compliance updates regarding RoHS and REACH standards before finalizing procurement decisions.

Ptc Resettable Fuses Selection Notes

Select this component when line-voltage-rated resettable protection is required for circuits operating at 120 VAC or VDC. Ensure the application current remains below the 160 mA hold current to prevent nuisance tripping during normal operation. Verify that the expected fault current does not exceed the 20 A maximum rating to maintain device integrity.
