MINISMDC150F/24-2

Overview

The Littelfuse MINISMDC150F/24-2 is a PolySwitch resettable fuse from the miniSMDC series, designed for surface mount applications. It features a holding current of 0.75 A and a trip current of 1.5 A. The device has a maximum voltage rating of 24 VDC and a maximum interrupting current (Imax) of 40 A. Its typical resistance is 90 mOhms, with a power dissipation of 800 mW. The component operates within a temperature range of -40°C to +85°C and is housed in an 1812 package.

Feature Summary

Provides overcurrent protection through automatic reset functionality upon cooling after fault clearance.
Utilizes polymer positive temperature coefficient technology for reliable circuit safeguarding.
Designed for surface mount integration on printed circuit boards.

Applications

Protection of portable electronic devices
Overcurrent safeguarding in battery-powered equipment
Circuit protection for telecommunications hardware

Procurement Notes

Verify the specific suffix designation against official Littelfuse documentation to confirm voltage ratings and package variations. Ensure compatibility with reflow soldering profiles and moisture sensitivity levels as defined in the manufacturer datasheet. Cross-reference part numbers to avoid confusion between similar series variants.

Selection Notes

Select this component when a compact surface mount solution is required for low-voltage DC circuits. The 0.75 A holding current suits applications needing precise overcurrent limits. Consider the 24 VDC rating and 1812 footprint constraints during PCB layout design to ensure adequate thermal management and spatial fit.

Part Context

This part belongs to the miniSMDC family of PolySwitch resettable fuses by Littelfuse. These components are engineered for high-reliability circuit protection in space-constrained environments. The series offers various current and voltage ratings to accommodate diverse electronic system requirements while maintaining a small physical profile.
