LVR012S-1

Ptc Resettable Fuses Overview

The Littelfuse LVR012S-1 is a PolySwitch resettable PPTC device from the LVR series, designed for line-voltage circuit protection. It features a 120VAC/VDC maximum voltage rating and a 100mA hold current. The component trips at 300mA and withstands a maximum fault current of 1.2A. Its initial resistance is 3 Ohms minimum, rising to 12 Ohms maximum after tripping. Rated for operation between -20°C and 85°C, it utilizes a radial leaded disc package with a 5.08mm lead spacing.

Ptc Resettable Fuses Feature Summary

• Provides automatic overcurrent and overtemperature protection for circuits operating at line voltages
• Offers reliable protection against mechanical overloads, overheating, stall, and lost neutral conditions in appliances
• Features low resistance characteristics compatible with standard fuse solutions while maintaining compact sizing

Ptc Resettable Fuses Applications

• Protection of electric motors in commercial and home appliances
• Transformer protection against damage from mechanical overloads or overheating
• Circuit safeguarding against lost neutral faults and other harmful electrical conditions

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix designation carefully, as the requested model differs from the primary datasheet example. Confirm that the 120VAC rating aligns with your system requirements rather than higher voltage variants. Ensure the radial lead configuration matches your PCB layout constraints. Validate agency approvals such as UL, CSA, and TUV for your target market compliance needs before finalizing procurement.

Ptc Resettable Fuses Selection Notes

Select this component when protecting low-current circuits up to 120VAC or VDC. The 100mA hold current suits sensitive electronics requiring precise trip thresholds. Consider the radial lead form factor for through-hole mounting applications where surface mount options are unsuitable. Evaluate the thermal environment to ensure operation within the specified temperature range without derating issues.

Ptc Resettable Fuses Part Context

This device belongs to the Littelfuse PolySwitch LVR series, which specializes in line-voltage-rated polymer positive temperature coefficient resettable fuses. These components are engineered specifically for commercial and home appliance markets. They provide robust defense against various electrical faults while offering a compact alternative to traditional fusible links.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other LVR series devices sharing identical 120VAC ratings and 100mA hold currents. Verify that substitute parts maintain the same radial leaded disc package dimensions and lead spacing to ensure physical compatibility on existing printed circuit boards.
