MINIASMDC110F/24-2

Overview

The Littelfuse MINIASMDC110F/24-2 is a PolySwitch resettable fuse from the miniASMD series, designed for surface mount applications. It features a hold current of 1.1 A and a trip current of 2.2 A, with a maximum voltage rating of 24 VDC. The component has a maximum resistance of 60 mOhms and can withstand a maximum fault current of 20 A. It operates within a temperature range of -40°C to +85°C and dissipates up to 0.8 W. The device is housed in an 1812 (4532 metric) package with a height of 0.62 mm.

Feature Summary

AEC-Q200 qualified for automotive reliability standards
Polymer PTC technology enables automatic circuit recovery after fault conditions
Compact surface mount design suitable for high-density PCB layouts

Applications

Automotive electronic circuits requiring AEC-Q200 compliance
Overcurrent protection for portable electronics and handheld devices
Protection of battery packs and power supply lines
Circuit safeguarding in networking equipment and servers

Procurement Notes

Verify that the specific suffix /24-2 matches the required 24VDC rating and 1.1A hold current specifications for your design. Confirm the manufacturer part number against official Littelfuse documentation to ensure correct variant selection. Check for AEC-Q200 certification requirements if the application involves automotive systems. Ensure compatibility with standard reflow soldering profiles during assembly planning.

Selection Notes

Select this component when a compact, resettable overcurrent protector is needed for low-voltage DC circuits. The 1.1A hold current suits moderate load protection needs. Consider the 24VDC rating to ensure it exceeds the system's operating voltage. Evaluate the 1812 footprint against available board space. Verify thermal dissipation capabilities relative to ambient operating temperatures.

Part Context

This part belongs to the miniASMD series of PolySwitch resettable fuses by Littelfuse. These components utilize polymer positive temperature coefficient technology to provide reusable circuit protection. The series is engineered for surface mount integration, offering a balance between current handling capacity and physical size for modern electronic assemblies.
