Overview
The MF-RG400-0-14 is a radial leaded PTC resettable fuse manufactured by Bourns Inc. It features a maximum holding current (Ih) of 4 A and a trip current (It) of 6.8 A. The device has a maximum voltage rating of 16 V and can withstand a maximum fault current of 100 A. Its physical height is 3 mm, and it utilizes a radial leaded package configuration.
Feature Summary
- Provides automatic circuit protection through positive temperature coefficient behavior
- Offers resettable functionality to restore service after fault conditions clear
- Designed for radial leaded mounting in through-hole applications
Applications
- Overcurrent protection in consumer electronics assemblies
- Circuit safeguarding in portable battery-powered devices
- Protection for low-voltage signal and power lines
Procurement Notes
Verify the specific suffix '0' against the datasheet to confirm the exact hold current variant, as Bourns uses suffixes to denote different current ratings within the RG400 series. Confirm that the 16V rating aligns with the system's maximum operating voltage. Ensure the radial lead form factor matches the PCB footprint requirements. Check for RoHS compliance status if required by assembly standards.
Selection Notes
Select this component when a resettable solution is preferred over one-time fuses for low-voltage circuits. The 4A holding current suits moderate load applications. The 16V rating limits use to low-voltage systems only. Consider the 100A max fault current capability for short-circuit scenarios. Evaluate the 3mm height for vertical space constraints in compact enclosures.
Part Context
This part belongs to the MF-RG400 series of PTC resettable fuses from Bourns. The series offers various hold currents and voltage ratings. The RG400 designation indicates a specific package size and lead style. This model represents a mid-range current option within the radial leaded product line.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching electrical parameters and mechanical dimensions independently.
