Ptc Resettable Fuses datasheet and documents for LVR200K-240

LVR200K-240

Ptc Resettable Fuses Overview

The Littelfuse LVR200K-240 is a PolySwitch resettable PPTC device rated for 240 VAC/VDC line voltages. It features a 200 mA hold current and a 400 mA trip current, with a maximum resistance of 12 Ohms. The component supports a maximum fault current of 2 A and dissipates up to 1 W of power. Designed for radial leaded PCB mounting, it operates within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

Provides overcurrent protection against surges and overtemperature faults in line-voltage circuits
Offers reliable protection for motors and transformers from mechanical overloads and stalls
Features low resistance compatible with standard fuse solutions

Ptc Resettable Fuses Applications

Protection of electric motors in commercial appliances
Transformer overload protection in home appliances
Circuit protection against lost neutral conditions

Ptc Resettable Fuses Procurement Notes

Verify the specific package configuration and lead type when ordering, as suffixes may indicate tape-and-reel or bulk packaging variations. Confirm that the application voltage does not exceed the 240 VAC/VDC rating. Ensure the circuit's steady-state current remains below the 200 mA hold current threshold to prevent nuisance tripping during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component for applications requiring line-voltage protection where space constraints favor compact radial-leaded devices over traditional fuses. Consider the 12 Ohm maximum resistance impact on circuit impedance. Verify that the expected fault currents remain within the 2 A maximum fault current rating to ensure proper device survival and reset capability.

Ptc Resettable Fuses Part Context

Part of the LVR series designed specifically for line-voltage environments. These devices utilize polymeric positive temperature coefficient technology to limit current by increasing resistance upon heating. The series provides an alternative to traditional fusible links in AC/DC line-rated applications.
