Overview
The Bourns MF-R700-0-99 is a radial leaded PolySwitch resettable fuse from the MF-R series, designed for overcurrent protection in electronic circuits. It features a maximum voltage rating of 30 VDC and a hold current of 7 A. The device trips at 14 A and withstands up to 40 A maximum fault current. With a low resistance of 20 mΩ, it operates within a temperature range of -40°C to +85°C. The component utilizes a bulk packaging format and has a height of 18 mm with a 10.2 mm lead spacing.
Feature Summary
- Provides automatic circuit recovery after fault conditions without manual replacement
- Offers robust overcurrent protection against potential damage to critical circuitry
- Features UL, CSA, and TUV agency approvals for safety compliance
Applications
- Overcurrent protection for consumer electronics
- Circuit safeguarding in industrial systems
- Protection for medical technology equipment
- Safeguarding network communication devices
Procurement Notes
Verify that the specific suffix '-0-99' aligns with the standard MF-R700 specifications provided by Bourns. Confirm that the required hold current of 7 A and trip current of 14 A match the design requirements. Ensure the 30 VDC maximum voltage rating is sufficient for the target application. Check that the radial package and 10.2 mm lead spacing fit the PCB layout constraints.
Selection Notes
Select this component when high current handling up to 40 A is required alongside a compact radial footprint. The 20 mΩ resistance minimizes power loss during normal operation. The wide operating temperature range supports diverse environmental conditions. Agency approvals simplify the certification process for end products requiring UL or TUV recognition.
Part Context
This part belongs to the Bourns Multifuse family, which provides overcurrent protection solutions. The MF-R series specifically offers radial leaded options suitable for through-hole mounting. These devices are engineered to protect critical loads from overcurrent faults across various market segments including automotive, industrial, and consumer applications.
Replacement Considerations
Direct substitutes include other MF-R700 variants with identical electrical ratings. Verify that any alternative maintains the same 7 A hold current and 30 VDC rating. Ensure the replacement also carries the necessary agency approvals if required by the design.
