1812L260SLPR

Ptc Resettable Fuses Overview

The Littelfuse 1812L260SLPR is a surface-mount polymeric PTC resettable fuse designed for circuit protection. It features a hold current of 2.6 A and a trip current of 6 A, operating at a maximum voltage of 6 VDC. The device has a low resistance of 10 mOhms and a maximum fault current rating of 50 A. Housed in an 1812 (4532 metric) concave package with dimensions of 4.5 mm length, 3.2 mm width, and 0.75 mm height, it supports operation between -40°C and +85°C. Power dissipation is rated at 800 mW.

Ptc Resettable Fuses Feature Summary

• Utilizes polymeric positive temperature coefficient technology for automatic reset functionality after fault clearance
• Features a low-resistance design to minimize power loss during normal operation
• Constructed with a concave surface profile to enhance solder joint reliability on printed circuit boards

Ptc Resettable Fuses Applications

• Portable electronic devices requiring overcurrent protection
• Consumer electronics circuits
• Communication equipment signal lines
• Battery pack protection systems

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix SLPR against the manufacturer's official datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure that the procurement documentation explicitly references the 1812L series family characteristics. Cross-check the hold current and trip current ratings with the application requirements before finalizing orders to prevent mismatched protection levels.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile surface-mount solution is required for 6V DC circuits. The 2.6A hold current suits moderate load applications, while the 50A max current provides robust fault tolerance. Consider the 10mOhm resistance impact on system efficiency. The concave package aids in visual inspection and mechanical stability during assembly processes.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse 1812L Series of PolyFuse resettable fuses. The series is characterized by its compact 1812 footprint and low resistance variants. The 1812L260SLPR specifically denotes the 2.6A hold current version within the Low Rho (LoRho) subset, optimized for minimal voltage drop in sensitive low-voltage applications.

Ptc Resettable Fuses Replacement Considerations

Compatible substitutes include other 1812L series parts with matching electrical ratings, such as the 1812L160PR for lower current needs or the 1812L260SL for standard packaging. Verify that any replacement maintains the 6VDC rating and 50A max current capacity to ensure equivalent circuit protection performance.
