Overview
The Bourns MF-R700-2-14 is a radial leaded Polymeric Positive Temperature Coefficient (PPTC) resettable fuse from the Multifuse series. It features a holding current of 7 A and a trip current of 13 A, with a maximum voltage rating of 16 V. The device has a minimum resistance of 25 mΩ and a maximum interrupting rating of 100 A. It operates within a temperature range of -40°C to +125°C and utilizes a 5.1 mm lead spacing for PCB mounting.
Feature Summary
- Provides automatic circuit protection through reversible thermal response to overcurrent conditions
- Designed for high-temperature environments with an extended operational range up to 125°C
- Utilizes radial leaded construction for reliable through-hole PCB integration
Applications
- Overcurrent protection in low-voltage electronic circuits
- Protection for portable devices and battery packs
- Industrial control system circuit safeguarding
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number with official Bourns documentation. Confirm that the specific suffix matches the required electrical ratings and package style. Ensure compliance with RoHS directives if applicable to your assembly requirements. Validate supplier authorization status before acquisition.
Selection Notes
Select this component when applications require a resettable fuse with a 7 A holding current and 16 V maximum voltage. Consider the 125°C maximum operating temperature for high-heat environments. Evaluate the 25 mΩ minimum resistance for low-power loss requirements. Ensure the radial lead pitch fits the target PCB layout constraints.
Part Context
This component belongs to the Bourns Multifuse PPTC resettable fuse family. These devices serve as reusable alternatives to traditional one-time fuses. The series offers various current and voltage ratings for diverse circuit protection needs across consumer electronics and industrial sectors.
Replacement Considerations
Consult official Bourns substitution guides for verified equivalents. Verify matching holding current, trip current, and voltage ratings. Ensure compatible package dimensions and lead spacing for direct replacement.
