Overview
The Bourns MF-RG800-2-14 is a radial leaded PPTC resettable fuse from the MF-RG series, rated for 16 VDC maximum voltage and 8 A hold current. It features a trip current of 13.6 A and a maximum fault current rating of 100 A. The device exhibits a typical resistance of 11 mΩ and operates within a temperature range of -40°C to +85°C. Designed for PCB mounting with a 5.1 mm lead spacing, it provides overcurrent protection in compact electronic assemblies.
Feature Summary
- Provides automatic circuit interruption upon overcurrent conditions using polymeric positive temperature coefficient technology.
- Offers repeated protection capability by resetting automatically after cooling following fault clearance.
- Features low impedance design to minimize power loss during normal operation.
Applications
- Overcurrent protection for portable electronics and battery packs
- Protection circuits in automotive electronic modules
- Surge protection for industrial control systems
Procurement Notes
Verify the specific suffix '-14' against the official Bourns datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the hold current and voltage ratings with your circuit design parameters before finalizing procurement orders.
Selection Notes
Select this component when an 8 A continuous current capacity and 16 VDC rating are required for radial through-hole applications. Consider the 11 mΩ resistance for thermal management calculations. Evaluate the 100 A maximum fault current capability against potential short-circuit scenarios in the target application environment.
Part Context
This part belongs to the Bourns Multifuse MF-RG series of high-current resettable fuses. The series is designed for robust protection in demanding environments, offering higher current handling capabilities compared to standard PPTC devices. The MF-RG line supports various mounting styles and current ratings for diverse industrial and consumer applications.
Replacement Considerations
Consult the Bourns official cross-reference guide for verified substitutes. Generic PPTC fuses may not match the specific trip characteristics or physical dimensions. Verify that any replacement maintains the same hold current, voltage rating, and package footprint to ensure circuit compatibility.
