MINIASMDC150F/12-2

Overview

The Littelfuse MINIASMDC150F/12-2 is a PolySwitch resettable polymer device (PPTC) from the miniASMD series, designed for surface mount applications. It features a hold current of 1.5 A and a trip current of 2.8 A, with a maximum voltage rating of 12 VDC. The component has a maximum resistance of 110 mOhms and an interrupting rating of 100 A. It operates within a temperature range of -40°C to +85°C and is housed in a compact 1812 (4532 metric) package.

Feature Summary

Utilizes polymeric PTC technology for automatic circuit protection against overcurrent conditions
Designed for surface mount integration on printed circuit boards
Provides reliable resettable functionality without requiring manual replacement after fault clearance

Applications

Protection of portable electronic devices
Overcurrent safeguarding in battery-powered equipment
Circuit protection for automotive electronics

Procurement Notes

Verify that the specific suffix /12-2 corresponds to the 12VDC voltage rating variant, as standard part numbers may differ. Confirm RoHS compliance status and ensure the ordering quantity aligns with the manufacturer's reel packaging requirements. Cross-reference the datasheet to validate thermal derating curves for your specific operating environment.

Selection Notes

Select this component when a low-profile surface mount solution is required for circuits operating at 12VDC or lower. Ensure the expected normal operating current remains below the 1.5A hold current threshold. Verify that the physical dimensions of the 1812 package fit the available PCB real estate and that the thermal characteristics support the application's heat dissipation needs.

Part Context

This device belongs to the miniASMD family of resettable fuses, which are engineered for high-reliability applications in space-constrained environments. The series utilizes advanced polymer technology to provide robust protection while maintaining a small footprint suitable for modern surface mount assembly processes.
