MINIASMDC150F/24-2

Overview

The Littelfuse MINIASMDC150F/24-2 is a PolySwitch miniASMD series resettable PTC fuse designed for surface mount applications. It features a 24 VDC maximum voltage rating and a 1.5 A hold current. The device trips at 3.0 A with a maximum trip time of 0.3 seconds. It supports a maximum fault current of 100 A and exhibits an initial resistance range between 90 mΩ and 290 mΩ. Operating within a temperature range of -40°C to +85°C, it utilizes tin-plated terminals and conforms to AEC-Q200 automotive standards.

Feature Summary

• Provides automatic circuit protection through polymer positive temperature coefficient technology that resets after fault clearance.
• Complies with AEC-Q200 qualification standards for automotive electronic component reliability.
• Features a compact 1812 surface mount package optimized for high-density PCB layouts.

Applications

• Automotive electronics circuits requiring AEC-Q200 compliance
• Overcurrent protection for portable consumer devices
• Battery pack protection in mobile equipment

Procurement Notes

Verify the specific suffix designation against official Littelfuse documentation to confirm voltage and current ratings. Ensure the ordering part number matches the required hold and trip currents for the target application. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement.

Selection Notes

Select this component based on the 1.5 A hold current and 24 VDC rating. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +85°C range. Consider the 100 A maximum fault current capability relative to potential short-circuit conditions in the protected circuit.

Part Context

This component belongs to the Littelfuse miniASMD series, which offers resettable overcurrent protection in a small form factor. The series is engineered for surface mount assembly and provides reliable circuit protection for sensitive electronics. It serves as a reusable alternative to traditional one-time fuses in modern electronic designs.

Replacement Considerations

Cross-reference with MINIASMDC150F/16-2 for lower voltage applications or MINIASMDC150F/60-2 for higher voltage requirements. Verify physical dimensions and terminal compatibility when substituting with other SMD PTC devices from different manufacturers.
