MINIASMDC030F-2

Overview

The Littelfuse MINIASMDC030F-2 is a polymer PTC self-resetting fuse from the miniASMD series, designed for surface mount applications. It features a maximum voltage rating of 30V and a hold current (Ih) of 0.3A. The device has a trip current (It) of 0.6A and a maximum fault current rating of 100A. It operates within a temperature range of -40°C to +85°C and is housed in an 0603 (1608 metric) package with a recessed design. This component is AEC-Q200 qualified for automotive reliability.

Feature Summary

• Self-resetting polymer PTC technology provides automatic circuit recovery after fault conditions clear.
• Automotive-grade qualification ensures reliability under harsh environmental conditions.
• Compact recessed surface mount footprint optimizes board space utilization.

Applications

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

Procurement Notes

Verify the specific suffix and packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the selected reel or cut tape quantity meets production requirements. Ensure compatibility with standard reflow soldering profiles used in your assembly line. Cross-reference the part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a compact, low-current overcurrent protection solution is required for automotive or industrial applications. The 0.3A hold current suits sensitive low-power circuits. Verify that the 30V rating aligns with the system's maximum operating voltage. Consider the 100A interrupting rating for potential short-circuit scenarios on the PCB.

Part Context

This part belongs to the PolySwitch miniASMD series, which offers smaller footprints compared to standard ASMD fuses. The series is engineered for high-reliability applications where space constraints are critical. It serves as a resettable alternative to traditional one-time fuses in modern electronic designs.

Replacement Considerations

Direct replacements must match the 0.3A hold current, 30V rating, and 0603 package size. Verify that any substitute component also holds AEC-Q200 certification if used in automotive contexts. Check for identical thermal characteristics and trip time curves to ensure circuit protection integrity remains unchanged.
