Overview
The Bourns MF-RG700-2-14 is a radial leaded PPTC resettable fuse from the Multifuse MF-RG series. It features a 7 A hold current and an 11.9 A trip current, designed for operation at a maximum voltage of 16 V. The device exhibits a low resistance of 13 mOhms and can withstand a maximum fault current of 100 A. It operates within a temperature range of -40 °C to +85 °C and dissipates up to 3 W. Physical dimensions include a length and width of 11.2 mm, a height of 3 mm, and a lead spacing of 5.1 mm.
Feature Summary
- Provides automatic circuit protection through self-resetting polymer positive temperature coefficient technology
- Offers high fault current tolerance with a rated maximum of 100 A
- Features low on-resistance to minimize power loss during normal operation
Applications
- Overcurrent protection in consumer electronics circuits
- Surge protection for LED driver applications
- Current control and thermal protection in industrial systems
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number MF-RG700-2-14 with official Bourns documentation. Confirm that the received units match the specified radial lead style and package dimensions. Ensure compliance with relevant safety standards and RoHS requirements as defined in the official datasheet before integration into production designs.
Selection Notes
Select this component when designing circuits requiring robust overcurrent protection with a 7 A continuous load capacity. The 16 V rating suits low-voltage DC applications. Consider the 13 mOhm resistance for efficiency calculations and the 100 A interrupt rating for surge scenarios. Verify that the PCB layout accommodates the 5.1 mm lead spacing and 11.2 mm footprint.
Part Context
This part belongs to the Bourns Multifuse MF-RG series of resettable fuses. These devices utilize polymer PTC technology to provide reusable overcurrent protection. The series is engineered for applications requiring reliable circuit interruption without manual replacement, offering a compact solution for protecting sensitive electronic components from damage due to excessive current flow.
Replacement Considerations
Consult official Bourns substitution guides for verified alternatives. Do not assume functional equivalence with generic PTC devices based solely on similar electrical ratings. Verify that any substitute matches the specific hold current, trip current, and physical mounting requirements.
