MINISMDC110F-2

Overview

The Littelfuse MINISMDC110F-2 is a PolySwitch resettable PPTC fuse in the miniSMD series. It features a 1.1 A hold current and 2.2 A trip current with an 8 VDC maximum voltage rating. The device offers a 100 A maximum interrupt current and 210 mOhms initial resistance. Housed in a 1812 (4532 metric) SMD package measuring 4.73 mm x 3.41 mm x 0.62 mm, it operates between -40°C and +85°C.

Feature Summary

Provides automatic circuit protection through reversible polymer switching action upon overcurrent events.
Designed for surface-mount integration within compact electronic assemblies.
Ensures component safety by limiting fault currents to specified maximum interrupt levels.

Applications

Portable consumer electronics power line protection
Automotive electronics circuit safeguarding
Industrial control system input/output protection

Procurement Notes

Verify manufacturer part number against official Littelfuse documentation to confirm exact electrical ratings and package dimensions. Ensure compatibility with standard reflow soldering profiles and moisture sensitivity handling requirements during assembly processes.

Selection Notes

Select this component when space-constrained designs require an 8 VDC rated resettable fuse with a 1.1 A holding capacity. The 1812 footprint suits applications needing moderate current protection without excessive board area consumption.

Part Context

This model belongs to the miniSMD family of PolySwitch resettable fuses. It shares functional characteristics with other Littelfuse SMD devices but is distinguished by its specific 1812 package size and 8 VDC voltage rating parameters.
