Ptc Resettable Fuses datasheet and documents for 1812L014DR

1812L014DR

Ptc Resettable Fuses Overview

The Littelfuse 1812L014DR is a PolySwitch resettable PTC fuse designed for surface-mount applications. It features a maximum voltage rating of 60V and a hold current (Ih) of 140 mA, with a trip current (It) of 340 mA. The device operates within a temperature range of -40°C to +85°C. Initial resistance (Ri) is typically 1.5 Ohms minimum, while post-trip resistance (R1) reaches up to 6 Ohms maximum. It has a maximum fault current rating of 10 A and is available in tape and reel or cut tape packaging.

Ptc Resettable Fuses Feature Summary

Provides reliable overcurrent protection by raising resistance as it heats to limit current flow
Automatically resets to low-resistance state after the fault condition clears and device cools
Designed for surface-mount installation on printed circuit boards

Ptc Resettable Fuses Applications

Secondary circuit protection for compact automotive electronics
Protection of actuators, screens, and small motors in commercial vehicles
Overcurrent safeguarding for telecommunications and networking equipment

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix DR corresponds to the required tape and reel packaging configuration rather than cut tape. Confirm RoHS 3 compliance status and check for any recent PCN updates regarding material changes or manufacturing site transfers before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a 60V maximum voltage rating and 140 mA hold current are required for surface-mount overcurrent protection. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range and that the initial resistance characteristics align with the circuit design requirements.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse 1812L series of PolySwitch resettable fuses. These devices utilize polymer technology to provide solid-state protection against overcurrent events.
