0805L260SLTHYR

Overview

The Littelfuse 0805L260SLTHYR is a PolySwitch resettable PTC device from the Low Rho SL series, designed for surface mount applications. It features a 1206 (3216 metric) package with dimensions of 3.4 mm length, 1.8 mm width, and 0.7 mm height. The component has a hold current of 2.6 A and a trip current of 5 A. It supports a maximum voltage of 6 VDC and offers a maximum fault current rating of 50 A. The initial resistance is 26 mOhms, with a power dissipation of 800 mW. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Provides automatic circuit protection through self-resetting polymeric positive temperature coefficient technology.
• Features low initial resistance to minimize power loss in sensitive circuits.
• Designed for compact surface mount integration with standardized footprint compatibility.

Applications

• Portable electronic devices requiring overcurrent protection
• Consumer electronics circuit boards
• Battery pack protection systems

Procurement Notes

Verify the specific suffix 'HYR' against official Littelfuse documentation to confirm tape and reel specifications or special handling requirements. Ensure the selected variant matches the required 6VDC rating and 2.6A hold current for the target application. Cross-reference the RoHS status and packaging format directly with the manufacturer's latest datasheet before ordering.

Selection Notes

Select this component when a low-profile SMD solution is needed for low-voltage DC circuits. The 2.6A hold current suits moderate load applications, while the 6VDC rating limits usage to low-voltage environments. Consider the 26 mOhm resistance for efficiency needs. Verify thermal management capabilities given the 800 mW power dissipation limit at elevated temperatures.

Part Context

This part belongs to the POLY-FUSE Low Rho SL family, which emphasizes reduced initial resistance compared to standard PPTC devices. The 0805L series designation indicates the package size code, though the physical dimensions correspond to the larger 1206 metric footprint. This series is engineered for high-reliability consumer and industrial applications requiring robust resettable fuse performance.

Replacement Considerations

Direct substitutes within the same Low Rho SL series include parts with identical 2.6A hold current and 6VDC ratings but different suffixes indicating alternate packaging or material compositions. Verify that any replacement maintains the 26 mOhm resistance and 50A max fault current specifications.
