MINIASMDC110F/16-2

Overview

The Littelfuse MINIASMDC110F/16-2 is a PolySwitch resettable PPTC fuse in the miniASMD series. It features a 16 VDC maximum voltage rating and a 1.1 A hold current. The trip current is specified at 2.2 A, with a maximum rated current of 40 A. Initial resistance is typically 210 mOhms. The component utilizes an SMD/SMT installation style within a 1812 (4532 metric) package. Operating temperature ranges from -40°C to +85°C. It carries AEC-Q200 automotive qualification.

Feature Summary

Provides overcurrent protection through automatic reset functionality upon fault clearance
Automotive-grade reliability certified under AEC-Q200 standards for harsh environments
Compact surface-mount design suitable for space-constrained PCB layouts

Applications

Automotive electronic circuit protection
Portable battery-powered device safeguarding
Industrial control unit overcurrent defense

Procurement Notes

Verify the specific suffix designation against official Littelfuse documentation to confirm voltage and current ratings. Ensure compatibility with AEC-Q200 requirements if used in automotive contexts. Check moisture sensitivity levels and reflow soldering profiles prior to assembly. Confirm package dimensions match the target footprint.

Selection Notes

Select this component when a 16V system requires 1.1A continuous protection with high surge tolerance. Consider the 1812 package size for available board space. Evaluate thermal dissipation needs given the 85°C maximum operating limit. Compare against other miniASMD variants for different voltage or current thresholds.

Part Context

This part belongs to the miniASMD family of resettable fuses designed for surface-mount applications. It shares the PolySwitch technology platform with similar Littelfuse components. The series offers various hold currents and voltage ratings within the same physical envelope.
