MINISMDC110F/16-2

Overview

The Littelfuse MINISMDC110F/16-2 is a surface-mount polymer PTC resettable fuse from the miniSMD series. It features a 1.1 A hold current and a 2.2 A trip current, rated for a maximum voltage of 16 VDC. The device offers a maximum fault current rating (Imax) of 40 A and an initial resistance of 210 mOhms maximum. Housed in a compact 1812 (4532 metric) package with dimensions of 4.73 mm length, 3.41 mm width, and 0.62 mm height, it operates within a temperature range of -40°C to +85°C.

Feature Summary

Provides automatic circuit protection through reversible polymer switching action upon overcurrent events
Designed for surface-mount assembly on printed circuit boards using standard SMD/SMT mounting techniques
Constructed as a polymeric positive temperature coefficient device for reliable resettable fusing

Applications

Portable electronic devices requiring compact overcurrent protection
Consumer electronics circuits needing surface-mount fuse solutions
Industrial control systems utilizing low-voltage DC power distribution

Procurement Notes

Verify the specific part number against official Littelfuse documentation to confirm the 16V rating variant. Ensure compatibility with the required 1.1A hold current and 1812 package dimensions for your design. Check for moisture sensitivity levels and reflow soldering profile requirements during procurement planning.

Selection Notes

Select this component when a 16VDC rated, 1.1A holding current PTC fuse is required in a 1812 footprint. Compare against other miniSMD variants if higher voltage ratings or different current thresholds are needed. Confirm that the 40A Imax rating meets the prospective fault current conditions of the target application circuit.

Part Context

This component belongs to the Littelfuse PolySwitch miniSMD family of resettable fuses. These devices utilize proprietary polymer technology to provide overcurrent protection in a small surface-mount form factor. The series is designed for applications where space constraints and automatic recovery after fault clearance are critical design factors.
