LVR008S

Ptc Resettable Fuses Overview

The Littelfuse LVR008S is a line-voltage-rated (LVR) polymeric positive temperature coefficient (PPTC) resettable device designed for circuit protection. It operates at line voltages of 120 VAC/VDC and 240 VAC/VDC with an operating current up to 2 A at 20°C. This component provides reliable overcurrent protection against mechanical overloads, overheating, stall, and lost neutral conditions in commercial and home appliances. The device features low resistance and is compatible with fuse solutions, offering a compact size while ensuring safety compliance.

Ptc Resettable Fuses Procurement Notes

Verify the specific part number suffix and package configuration against official Littelfuse documentation to ensure compatibility with your design requirements. Confirm that the selected variant meets all necessary agency approvals and environmental compliance standards such as RoHS. Cross-reference datasheet specifications for maximum operating voltage and trip current to validate suitability for the intended application environment.

Ptc Resettable Fuses Selection Notes

Select this component when designing circuits requiring resettable protection for line-voltage rated applications up to 240 VAC/VDC. Ensure the operating current does not exceed 2 A at 20°C to maintain proper function. Consider the physical size constraints as it is compatibly sized with fuse solutions. Verify that the application involves risks such as mechanical overload or overheating where a resettable device offers operational advantages over one-time fuses.

Ptc Resettable Fuses Part Context

The LVR008S belongs to the Littelfuse Line-Voltage-Rated (LVR) product line, which specializes in polymeric positive temperature coefficient (PPTC) devices. This series is engineered specifically to protect electrical components in commercial and residential appliances from hazardous conditions like overcurrent surges and overtemperature faults. The LVR series distinguishes itself by offering a broad range of radial-leaded resettable devices suitable for direct line-voltage integration.

Ptc Resettable Fuses Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalent parts. Ensure any replacement maintains the same line-voltage rating, current capacity, and package type. Generic PPTC devices may not offer identical performance in high-voltage appliance applications.
