MINISMDC110F/24-2

Overview

The MINISMDC110F/24-2 is a PolySwitch resettable fuse from the miniSMDC series, designed for surface mount applications. It features a hold current of 1.1A and a trip current of 2.2A at 24VDC. The component has a maximum rated current of 20A and a resistance of 0.06 ohms. It operates within a temperature range of -40°C to +85°C with a power dissipation of 0.8W. The device utilizes an 1812 (4532 metric) package with solder pad terminals.

Feature Summary

Provides overcurrent protection through automatic reset functionality upon fault removal
Utilizes polymeric positive temperature coefficient technology for rapid response
Designed for surface mount integration into compact circuit boards

Applications

Portable electronic devices requiring compact overcurrent protection
Consumer electronics circuits needing resettable fuse solutions
Industrial control systems utilizing low voltage DC power lines

Procurement Notes

Verify the specific suffix /24-2 against official Littelfuse documentation to confirm voltage rating and packaging details. Ensure compatibility with standard reflow soldering profiles. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly. Cross-reference datasheet parameters with system requirements to validate electrical performance under operating conditions.

Selection Notes

Select this component when space constraints require an 1812 footprint for resettable fusing. Choose based on the 1.1A hold current requirement for the protected circuit. Consider the 24VDC voltage rating for appropriate insulation and breakdown safety. Evaluate thermal management needs given the 0.8W power dissipation specification in enclosed environments.

Part Context

This part belongs to the miniSMDC family of PolySwitch resettable fuses manufactured by Littelfuse. These components are engineered for high-reliability applications where traditional fusible links are impractical due to maintenance requirements. The series offers various current ratings and package sizes to accommodate diverse PCB layout needs.
