LVR008NS

Ptc Resettable Fuses Overview

The Littelfuse LVR008NS is a line-voltage-rated polymeric positive temperature coefficient (PPTC) resettable fuse designed for AC/DC circuits up to 240V. It features an 80mA hold current and a 1.2A trip current, providing overcurrent and overtemperature protection. The device utilizes radial leads for through-hole mounting and offers low resistance comparable to traditional fuses. It is compliant with RoHS and halogen-free standards, ensuring safe operation in commercial and home appliances against mechanical overloads, overheating, and stall conditions.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit interruption during overcurrent or overtemperature faults without requiring replacement
• Rated for line voltages of 120V and 240V AC/DC for broad compatibility
• Radial-leaded construction allows for easy through-hole integration into printed circuit boards
• RoHS and halogen-free compliant for environmentally conscious manufacturing

Ptc Resettable Fuses Applications

• Protection of electric motors in commercial and home appliances
• Transformer protection against mechanical overloads and lost neutral conditions
• Overcurrent protection for power supplies operating at line voltage levels

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix designation when ordering, as Littelfuse offers variants such as LVR008NS-1 and LVR008NS-2 which may differ in lead configuration or packaging. Confirm that the selected variant meets the required safety certifications for your target market. Ensure the PCB layout accommodates the radial lead spacing and thermal requirements for proper heat dissipation during tripping events.

Ptc Resettable Fuses Selection Notes

Select this component for applications requiring resettable protection at 240V ratings where space is limited compared to traditional fuses. The 80mA hold current suits low-power control circuits. Consider the thermal environment, as PPTC devices rely on ambient temperature for resetting. Verify that the maximum fault current capability exceeds the prospective short-circuit current of the protected circuit to ensure safe interruption.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse Line-Voltage-Rated (LVR) PolySwitch family, which provides the industry's broadest range of radial-leaded resettable devices. These components are engineered to replace traditional fuses in line-voltage applications, offering reusable protection for sensitive electronics in consumer and industrial equipment while maintaining compact form factors.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include Littelfuse LVR008NS-1 and LVR008NS-2. Verify lead length and bend radius specifications if replacing with these variants to ensure mechanical fit within the existing enclosure or PCB footprint.
