MINIASMDC075F-2

Overview

The Littelfuse MINIASMDC075F-2 is a PolySwitch resettable PTC fuse in the miniASMD series, designed for surface mount applications. It features a 24V maximum voltage rating and a 750mA hold current. The device trips at 1.5A with a typical time of 300ms. It offers a maximum interrupting rating of 40A and operates within a temperature range of -40°C to 85°C. The component is AEC-Q200 qualified for automotive use and complies with RoHS standards.

Feature Summary

• Provides overcurrent protection through automatic resistance increase during fault conditions
• Designed for surface mount integration on printed circuit boards
• Qualified for automotive electronic environments under AEC-Q200 standards

Applications

• Automotive electronic circuits requiring AEC-Q200 compliance
• Portable consumer electronics protection
• Battery-powered device circuit safeguarding

Procurement Notes

Verify the specific suffix and voltage rating against the target schematic requirements. Confirm that the package dimensions align with the PCB footprint design. Ensure the hold current meets the operational load specifications without nuisance tripping. Check for RoHS compliance status if required by project regulations.

Selection Notes

Select this component when a compact, automotive-grade resettable fuse is needed for low-voltage DC circuits. The 24V rating suits battery systems and low-power logic supplies. Consider the thermal derating curves for high ambient temperatures. Verify that the trip current accommodates inrush currents without false activation.

Part Context

This part belongs to the miniASMD series of PolySwitch resettable fuses. It represents a smaller form factor compared to standard SMD fuses, suitable for space-constrained designs. The series provides reliable circuit protection for sensitive components against short circuits and overloads.
