Overview
The MINISMDC200-2 is a surface-mount PolySwitch resettable PTC device manufactured by Littelfuse. It functions as an overcurrent protection component that increases resistance upon heating to limit current flow during fault conditions. The device is designed for PCB integration, offering reliable circuit safeguarding against shorts and overloads while maintaining a compact form factor suitable for space-constrained electronic assemblies.
Feature Summary
- Provides automatic resettable overcurrent protection without requiring manual replacement after fault clearance
- Increases electrical resistance dynamically when heated by excessive current to limit circuit flow
- Designed for direct soldering onto printed circuit boards for secure mechanical and electrical attachment
Applications
- Protection of telecommunication network equipment circuits
- Overcurrent safeguarding in AC-DC power supply modules
- Circuit protection for automotive electronic subsystems
- Surge and overload defense in portable consumer electronics
Procurement Notes
Verify the specific Littelfuse datasheet for the MINISMDC200-2 to confirm exact hold current and trip current ratings required for your design. Ensure the selected variant matches the voltage and current specifications of the target application circuit. Cross-reference with official manufacturer documentation to validate compliance with relevant safety standards before finalizing procurement orders.
Selection Notes
Select this component based on the maximum operating voltage and continuous current requirements of the protected circuit. Evaluate the thermal environment to ensure the device can dissipate heat effectively during normal operation. Confirm that the surface-mount package dimensions fit within the available PCB real estate constraints for the intended assembly layout.
Part Context
This part belongs to the MiniSMDC series of PolySwitch resettable fuses from Littelfuse. These devices are engineered for surface-mount applications, providing a compact alternative to traditional axial leaded fuses. The series is widely utilized in industries requiring reliable, self-resetting overcurrent protection for sensitive electronic components and integrated circuits.
Replacement Considerations
Compatible substitutes include the MINISMDC200F and other variants within the MiniSMDC family. Verify that any replacement part maintains identical voltage ratings, hold currents, and physical footprint dimensions to ensure seamless integration into existing circuit designs without modification.
