MF-USML200/6-2

Overview

The Bourns MF-USML200/6-2 is a surface-mount polymeric resettable fuse (PPTC) from the Multifuse USML series, designed for overcurrent protection in compact electronic assemblies. This component features a low-profile design suitable for space-constrained applications and utilizes a halogen-free polymer composite to ensure environmental compliance. It provides reliable circuit protection by increasing resistance in response to excessive current flow, automatically resetting once the fault condition is removed and the device cools down.

Feature Summary

• Halogen-free construction for environmental compliance
• Low-profile surface-mount package for space efficiency
• Automatic reset functionality after fault removal

Applications

• Portable consumer electronics
• Laptop and tablet peripheral ports
• Battery pack protection circuits

Procurement Notes

Verify the specific suffix codes on the ordering information to confirm the exact tape-and-reel packaging configuration and quantity per reel. Ensure that the selected variant matches the required voltage and current ratings for the target application. Cross-reference the manufacturer's latest datasheet to confirm RoHS compliance status and material declarations before finalizing procurement orders.

Selection Notes

Select this component based on its hold current and trip current specifications relative to the operating parameters of the protected circuit. Evaluate the maximum fault current capability to ensure the device can withstand potential surge conditions without damage. Consider the physical dimensions and thermal environment of the PCB layout to guarantee adequate heat dissipation during normal operation and fault events.

Part Context

This part belongs to the Multifuse USML series, which represents Bourns' high-performance line of surface-mount resettable fuses. The series is engineered for demanding applications requiring robust protection in minimal footprint designs. It complements other Bourns circuit protection solutions by offering a reliable alternative to traditional fusible links in modern portable devices.

Replacement Considerations

Direct replacements include the MF-USML150/6-2 or MF-USML350/6-2 from the same series, depending on whether lower or higher current thresholds are required. Verify that any substitute maintains the same voltage rating and package dimensions to ensure mechanical compatibility.
