1206L260SLTHYR

Ptc Resettable Fuses Overview

The Littelfuse 1206L260SLTHYR is a POLYFUSE Low Rho PolyFuse Resettable PTC device in a 1206 (3216 metric) SMD/SMT package. It features a hold current of 2.6 A, trip current of 5 A, and maximum voltage rating of 6 VDC. The component has an initial resistance of 26 mOhms and a maximum rated current of 50 A. Operating temperature range is -40°C to +85°C with dimensions of 3.4 mm length, 1.8 mm width, and 0.7 mm height.

Ptc Resettable Fuses Feature Summary

• Provides overcurrent protection through automatic reset functionality upon cooling after fault removal
• Utilizes polymer technology for low resistance characteristics within the Low Rho series
• Designed for surface mount assembly on printed circuit boards

Ptc Resettable Fuses Applications

• Portable electronic devices requiring compact circuit protection
• Battery packs and power management circuits
• Interface ports and data lines in consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix SLTHYR matches the required reel or cut tape packaging configuration for your manufacturing line. Confirm that the 6 VDC maximum voltage rating aligns with the system's operating parameters to ensure adequate safety margins during transient events. Check RoHS compliance status if restricted substances are mandated by project specifications.

Ptc Resettable Fuses Selection Notes

Select this component when a low initial resistance is critical to minimize voltage drop in high-current paths. The 2.6 A hold current suits applications with steady-state loads near this threshold. Ensure the 6 VDC rating accommodates peak voltages without exceeding limits. Consider the 1206 footprint constraints and thermal dissipation requirements of 800 mW for proper PCB layout.

Ptc Resettable Fuses Part Context

This part belongs to the POLYFUSE Low Rho series, designed for applications demanding lower resistance than standard PPTC devices. It serves as a reusable alternative to one-time fuses in space-constrained environments. The 1206 package allows for automated surface mount placement, supporting high-volume production of modern electronic assemblies.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include parts from other manufacturers offering similar 1206 form factors and 2.6 A ratings. Verify electrical parameters such as hold current, trip current, and maximum voltage before substitution. Ensure the replacement device meets the same thermal and mechanical reliability standards.
