Overview
The Bourns MF-S200 is a polymer PTC resettable fuse from the Multifuse MF-S series, designed for overcurrent protection. It features a maximum voltage of 30V and a hold current (Ih) of 2A. The trip current (It) is specified at 4.4A. Initial resistance (Ri) is typically 30 mOhms minimum, with a maximum post-trip resistance (R1) of 80 mOhms. The device supports a maximum fault current of 100A and operates within a temperature range of -40°C to 85°C. Dimensions are 22.35mm x 10.60mm x 1.10mm.
Feature Summary
- Provides automatic circuit recovery after overcurrent events without manual replacement
- Offers dual certification from cURus and TUV for international compliance
- Constructed from polymer material for robust thermal stability
Applications
- Consumer electronics power supply protection
- Industrial equipment circuit safeguarding
- Telecommunications system overcurrent defense
Procurement Notes
Verify component authenticity through authorized Bourns distributors or certified partners. Confirm RoHS3 compliance status and check for specific manufacturing date codes if required for legacy integration. Ensure storage conditions maintain moisture sensitivity level 1 integrity prior to assembly.
Selection Notes
Select this component when a 2A hold current and 30V rating suit the circuit design. Consider the strap package style for user-defined mounting requirements. Evaluate the 80 mOhms maximum resistance limit against voltage drop constraints in the application path.
Part Context
Part of the Multifuse MF-S series, this polymer PTC fuse serves as a reusable alternative to traditional fuses. It belongs to Bourns' broader portfolio of circuit protection devices, offering reliable performance in compact form factors for various electronic assemblies.
Replacement Considerations
The MF-S200S is listed as an obsolete substitute option. Verify electrical parameter compatibility before cross-referencing other manufacturers' equivalents to ensure match in voltage, current, and physical dimensions.
