AGRF1100-2

Ptc Resettable Fuses Overview

The Littelfuse AGRF1100-2 is a PolySwitch polymer PTC resettable fuse designed for radial through-hole PCB mounting. It features a maximum operating voltage of 16V and a hold current of 11A. The trip current is specified at 20.3A, with a maximum interrupt rating of 100A. Initial resistance is 3.3 mOhms minimum, while post-trip resistance reaches up to 8.9 mOhms maximum. It operates within a temperature range of -40°C to 85°C and holds AEC-Q200 automotive qualification.

Ptc Resettable Fuses Feature Summary

• Utilizes polymer technology for automatic circuit protection without manual replacement
• Provides radial leaded installation compatible with standard PCB layouts
• Meets AEC-Q200 automotive grade reliability standards

Ptc Resettable Fuses Applications

• Automotive electronics circuit protection
• Consumer device overcurrent safeguarding
• Industrial control system component protection

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix '2' against official Littelfuse documentation to confirm package type and reel specifications. Ensure the required hold current aligns with the 11A specification for the target application environment. Confirm that the 16V maximum voltage rating is sufficient for the circuit's peak operating conditions. Check for any updated RoHS compliance status in the latest datasheet revision.

Ptc Resettable Fuses Selection Notes

Select this component when an 11A continuous current capacity is required in a low-voltage 16V system. The radial package facilitates easy insertion into existing through-hole designs. Consider the 8.9 mOhms maximum post-trip resistance for potential voltage drop impacts. Verify thermal management requirements given the -40°C to 85°C operational range.

Ptc Resettable Fuses Part Context

This part belongs to the AGRF series of resettable fuses from Littelfuse. It serves as a reusable alternative to traditional fusible links in circuits requiring overcurrent protection. The series is engineered for applications demanding high reliability and repeated fault recovery capabilities.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other AGRF series variants with adjusted current ratings, such as AGRF1000-2 or AGRF1200-2, provided they match the 16V voltage rating and radial package constraints.
