Overview
The Littelfuse MICROASMD005F-2 is a surface-mount polymer PTC resettable fuse from the microASMD series. It features a holding current of 50 mA and a trip current of 150 mA, rated for a maximum voltage of 30 VDC. The device has a maximum fault current rating of 10 A and an initial resistance of 50 ohms. Housed in a 1210 (3225 metric) package, it operates within a temperature range of -40°C to +85°C. This component is qualified under AEC-Q200 standards for automotive applications.
Feature Summary
- Surface-mount polymer PTC technology providing automatic circuit protection
- AEC-Q200 qualification ensuring reliability for automotive environments
- Compact 1210 footprint designed for space-constrained PCB layouts
Applications
- Automotive electronics circuits requiring overcurrent protection
- Portable consumer electronic devices
- Industrial control systems
Procurement Notes
Verify the specific ordering suffix matches the required tolerance and packaging configuration. Confirm that the AEC-Q200 qualification aligns with target automotive application requirements. Ensure the 1210 package dimensions are compatible with the intended PCB footprint and reflow soldering profile.
Selection Notes
Select this component when a low holding current near 50 mA is required for sensitive circuit protection. The 30 VDC rating suits low-voltage DC bus applications. Consider the 50 ohm initial resistance impact on signal integrity or power loss in the design phase. Verify thermal dissipation capabilities within the enclosed assembly.
Part Context
This part belongs to the microASMD series of resettable fuses, positioned between nano and pico variants in terms of physical size and current handling. It offers a balance between compactness and robust fault protection compared to smaller SMD fuses, serving as a reliable alternative to traditional one-time fuses in modern electronics.
Replacement Considerations
Direct substitutes include other 50 mA, 30 VDC PPTC fuses in the 1210 package from Littelfuse or competitors. Verify that any replacement maintains identical AEC-Q200 qualification and thermal characteristics.
