Overview
The Littelfuse MINISMDC200F/16-2 is a surface-mount PolySwitch resettable PTC fuse designed for overcurrent protection. It features a hold current of 2A and a trip current of 4A at a maximum voltage of 16VDC. The device has a typical resistance of 20mΩ and a maximum fault current rating of 40A. Packaged in an 1812 (4532 metric) footprint, it operates within a temperature range of -40°C to +85°C.
Feature Summary
- Provides reliable overcurrent protection by increasing resistance during fault conditions
- Automotive-grade component certified to AEC-Q200 standards
- Compact surface-mount design suitable for space-constrained PCB layouts
Applications
- Protection of automotive actuators and small motors
- Overcurrent safeguarding for battery-powered devices
- Circuit protection in telecommunications equipment
Procurement Notes
Verify the specific suffix configuration when ordering, as variations exist between MINISMDC200F-2 and MINISMDC200F/16-2 regarding voltage ratings. Confirm that the selected variant matches the system's maximum operating voltage requirements. Ensure compatibility with standard reflow soldering profiles and check moisture sensitivity levels for storage handling procedures prior to assembly.
Selection Notes
Select this component for applications requiring robust overcurrent protection in low-voltage DC circuits. The 16V rating distinguishes it from higher voltage variants like the 8V or 24V versions within the miniSMDC family. Consider the 1812 package size for board space optimization while ensuring the 2A hold current aligns with normal operational loads without nuisance tripping.
Part Context
This part belongs to the miniSMDC series of PolySwitch resettable fuses manufactured by Littelfuse. These devices are engineered for compact electronic designs where traditional fuses are impractical. The series offers various voltage and current ratings to suit diverse circuit protection needs across industrial and consumer electronics sectors.
Replacement Considerations
MINISMDC200F-2 serves as a functional substitute within the same series, though voltage ratings may differ. Verify electrical parameters against original design specifications before substitution.
