Overview
The Bourns MF-R700-0-14 is a radial leaded PPTC 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, with a trip current of 14 A. The device can withstand a maximum fault current of 40 A and has an initial resistance of 20 mOhms. It operates within a temperature range of -40°C to +85°C and utilizes a 10.2 mm lead spacing for PCB mounting.
Feature Summary
- Provides automatic circuit recovery after fault conditions clear
- Offers high fault current capability up to 40 A
- Features low initial resistance for minimal power loss
Applications
- Consumer electronics power supply protection
- Industrial control circuit overcurrent safeguarding
- Automotive accessory circuit protection
Procurement Notes
Verify that the specific suffix '-0-14' matches the required packaging or tape-and-reel configuration if applicable, as standard MF-R700 units are often supplied in bulk. Confirm RoHS compliance status and lead-free solderability requirements against the latest manufacturer datasheet before finalizing procurement orders to ensure regulatory adherence.
Selection Notes
Select this component when a 7 A hold current and 30 VDC rating align with system requirements. Ensure the 10.2 mm lead spacing fits the PCB layout constraints. Consider the 20 mOhms resistance impact on voltage drop and thermal management within the specific application environment compared to alternative current ratings.
Part Context
This part belongs to the Bourns MF-R series of polymer positive temperature coefficient resettable fuses. These devices are engineered for through-hole mounting and provide reliable overcurrent protection without requiring replacement after tripping. The series is widely used in applications demanding robust, reusable circuit protection solutions.
Replacement Considerations
The Littelfuse RLD30P700UF is a confirmed parameter-equivalent substitute offering similar 30V 7A specifications. Verify pin compatibility and thermal characteristics during integration to ensure seamless replacement functionality.
