Overview
The MINISMDC200F-2 is a PolySwitch resettable fuse from the miniSMD series, designed for surface mount applications. It features a hold current of 2 A and a trip current of 4 A, with a maximum voltage rating of 8 VDC. The device has a maximum rated current of 100 A and an initial resistance of 70 mOhms. Packaged in a 1812 (4532 metric) footprint, it operates within a temperature range of -40°C to +85°C.
Feature Summary
- Provides overcurrent protection through polymer PTC technology that resets automatically after fault clearance.
- Designed for surface mount integration on printed circuit boards to protect sensitive components.
- Offers high interrupting capability to handle short circuit events safely.
Applications
- Protection of portable electronic devices
- Overcurrent safeguarding in battery-powered equipment
- Circuit protection for telecommunications hardware
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number with official Littelfuse documentation. Confirm package dimensions and electrical ratings match design requirements before procurement. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain reliability upon soldering.
Selection Notes
Select this component when low voltage operation near 8 VDC is required alongside a 2 A continuous load capacity. The compact 1812 form factor suits space-constrained layouts. Evaluate thermal dissipation needs as power loss increases significantly during tripped states compared to normal operation.
Part Context
This part belongs to the miniSMD family of resettable fuses, which are characterized by their small physical size relative to standard SMD fuses. The series utilizes polymeric positive temperature coefficient materials to provide reliable circuit protection without requiring replacement after activation.
Replacement Considerations
MINIASMDC200F/16-2 serves as a qualified automotive-grade alternative within the same manufacturer portfolio, offering similar electrical characteristics but with enhanced qualification standards for harsh environments.
