MF-R800-2-99

Overview

The Bourns MF-R800-2-99 is a polymeric PTC resettable fuse rated for 30V DC with an 8A hold current. It features a radial through-hole package with a 10.2mm lead spacing and dimensions of 24.20 x 3.00mm. The device trips at 16A within 18.8 seconds, offering initial resistance as low as 5mΩ and maximum post-trip resistance of 30mΩ. It supports a maximum surge current of 40A and dissipates up to 4W, operating reliably between -40°C and +85°C.

Feature Summary

Polymeric construction provides self-resetting functionality after fault clearance
Radial through-hole design facilitates standard PCB mounting
RoHS compliant and lead-free manufacturing process

Applications

Overcurrent protection in multi-port charging systems
Short circuit protection for consumer electronics output ports
Industrial equipment circuit safeguarding

Procurement Notes

Verify the specific suffix '-2-99' against official Bourns documentation to confirm packaging configuration and compliance status. Ensure the procurement channel sources genuine components matching the MF-R series specifications. Cross-reference the lead spacing and dimensional tolerances with the target PCB footprint requirements prior to ordering.

Selection Notes

Select this component when a high-current 8A protection level is required for 30V DC circuits. The radial form factor suits applications where automated surface-mount placement is not feasible. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +85°C range during continuous load conditions.

Part Context

This part belongs to the Bourns MF-R series of multifuse devices. These components utilize polymer positive temperature coefficient technology to provide overcurrent protection. The series is designed for use in various electronic assemblies requiring reliable, reusable circuit interruption capabilities without manual replacement.

Replacement Considerations

Consult official substitution guides for equivalent polymeric PTC fuses with matching 8A hold current and 30V ratings. Verify that alternative parts maintain compatible radial lead spacing and dimensional constraints for existing board layouts.
