Overview
The Littelfuse MINISMDC020F-2 is a PolySwitch resettable PPTC fuse in the miniSMD series. It features a 200 mA hold current and 400 mA trip current, rated for 30 VDC maximum voltage. The device has a maximum resistance of 3.3 Ohms and handles 10 A maximum fault current (Imax). Packaged in an 1812 surface-mount footprint measuring 4.73 mm x 3.41 mm x 0.89 mm, it operates between -40°C and +85°C with 800 mW power dissipation.
Feature Summary
- Provides automatic circuit protection through reversible polymer switching behavior
- Designed for compact surface-mount assembly on printed circuit boards
- Offers high fault current interruption capability within specified limits
Applications
- Portable electronic device overcurrent protection
- Consumer electronics circuit safeguarding
- Automotive infotainment system protection
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package dimensions and terminal material match the 1812 form factor. Ensure storage conditions respect moisture sensitivity levels to prevent solderability issues during reflow processes.
Selection Notes
Select this component when space constraints require a small SMD footprint alongside low current requirements. Evaluate thermal derating curves to ensure reliable operation at elevated ambient temperatures. Compare trip characteristics against downstream component withstand capabilities to prevent damage during fault events.
Part Context
This part belongs to the miniSMD family of PolySwitch resettable fuses from Littelfuse. These devices utilize positive temperature coefficient polymer technology to provide reusable overcurrent protection. The series offers various hold currents and voltage ratings optimized for modern electronic applications requiring compact protection solutions.
Replacement Considerations
Direct substitutes include MINISMDC020F/33-2 for higher voltage applications or NANOSMDC020F-2 for smaller footprints. Verify that alternative parts maintain equivalent hold current, trip current, and maximum voltage ratings to ensure circuit compatibility.
