Overview
The Bourns MF-RG700-0 is a high-density polymeric positive temperature coefficient (PPTC) resettable fuse from the Multifuse MF-RG series. It features a radial leaded package designed for printed circuit board mounting. The device maintains a hold current of 7 A and trips at 11.9 A, with a maximum voltage rating of 16 V. It offers a high fault current interruption capability of 100 A maximum and exhibits a low initial resistance of 13 mOhms. The component operates within a temperature range of -40°C to +85°C and has a lead spacing of 5.1 mm.
Feature Summary
- Provides automatic circuit protection through self-resetting PPTC technology
- Engineered for high-density applications with compact radial footprint
- Capable of interrupting high fault currents up to 100 A
Applications
- Overcurrent protection in portable electronic devices
- Protection circuits for battery-powered equipment
- Interface protection for universal serial bus (USB) ports
Procurement Notes
Verify the specific suffix against official Bourns documentation to confirm packaging type and tolerance. Confirm that the 16 V rating aligns with the target circuit voltage. Ensure the PCB layout accommodates the 5.1 mm lead spacing and thermal requirements for a 7 A hold current application.
Selection Notes
Select this component when a 7 A continuous current capacity is required in a low-voltage environment. The 13 mOhms resistance minimizes power loss during normal operation. Consider the 100 A trip rating for robust fault protection in sensitive electronics where standard fuses are impractical due to reset requirements.
Part Context
This part belongs to the Bourns Multifuse MF-RG series, which specializes in high-current resettable fuses. The series is characterized by its ability to handle significant overcurrent events while maintaining a small physical profile suitable for modern surface mount and through-hole PCB designs requiring reliable overcurrent management.
Replacement Considerations
Cross-reference with MF-RG700-2 or MF-RG700-AP for identical electrical specifications but different packaging formats such as reel or ammo pack configurations.
