1206L700SLPR

Ptc Resettable Fuses Overview

The Littelfuse 1206L700SLPR is a surface-mount polymer PTC self-resetting fuse from the POLY-FUSE LoRho series. It features a hold current of 7 A, trip current of 14 A, and maximum voltage of 12 VDC. The device has a maximum rated current of 50 A and an initial resistance of 3.5 mOhms. It operates within a temperature range of -40°C to +85°C and is available in cut tape or reel packaging.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection by increasing resistance during overcurrent conditions
• Self-resetting functionality eliminates the need for manual replacement after fault clearance
• Low resistance design minimizes power loss and heat generation during normal operation

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Circuit safeguarding in automotive electronics
• Protection for communication equipment and data lines
• Power supply input protection in industrial systems

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix SLPR against official Littelfuse documentation to confirm packaging type and tape dimensions. Ensure the requested quantity aligns with standard reel or cut-tape availability. Cross-reference the RoHS compliance status with the latest manufacturer certificates prior to final procurement authorization.

Ptc Resettable Fuses Selection Notes

Select this component when a high hold current near 7 A is required in a compact 1206 footprint. Consider the low resistance characteristic for efficiency-sensitive designs. Evaluate the 12 VDC rating against the system's maximum operating voltage to ensure adequate safety margins under all load conditions.

Ptc Resettable Fuses Part Context

This part belongs to the POLY-FUSE LoRho series, which specializes in low-resistance surface-mount PPTCs. The series is engineered for applications demanding minimal voltage drop and thermal impact. The 1206 package offers a balance between current handling capacity and board space efficiency for modern dense PCB layouts.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 1206 L-series variants with matching 7 A hold current ratings, such as 1206L700/12SLPR. Verify that alternative parts maintain identical voltage ratings and physical dimensions to ensure compatibility with existing footprints and thermal profiles.
