MF-R800-2-14

Overview

The Bourns MF-R800-2-14 is a radial leaded PTC resettable fuse from the MF-R series, designed for overcurrent protection in low-voltage circuits. It features a hold current of 8A and a trip current of 16A at a maximum voltage of 30V DC. The component has an initial resistance minimum of 5mΩ and a maximum post-trip resistance of 30mΩ. It operates within a temperature range of -40°C to +85°C and dissipates up to 4W. Dimensions are 24.20 x 3.00mm with a height of 32.90mm.

Feature Summary

Radial leaded construction with cured flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements.
RoHS compliant and halogen-free design suitable for environmentally sensitive applications.
Self-resetting functionality restores circuit continuity after fault conditions clear.

Applications

Overcurrent and short circuit protection in general electronics.
Load protection for computer peripherals and consumer products.
Circuit safeguarding in automotive applications.

Procurement Notes

Verify the specific ordering suffix matches the required lead length and packaging configuration. Confirm that the 30V DC rating aligns with the system's maximum operating voltage. Ensure the 8A hold current exceeds the normal operating load while remaining below the 16A trip threshold. Check compliance requirements against RoHS and halogen-free standards for the target market.

Selection Notes

Select this component when a low-voltage, high-current protection solution is required for through-hole mounting. The 8A hold current suits moderate power loads where rapid response to overcurrent events is necessary. Consider the 30V maximum voltage limit and ensure the application does not exceed this potential. The radial lead style facilitates easy insertion into standard PCB layouts.

Part Context

This part belongs to the Bourns MF-R Multifuse series of polymeric resettable fuses. These devices provide reliable circuit protection across various industries including computers, telecommunications, and automotive sectors. The MF-R series is characterized by its robust epoxy encapsulation and consistent performance under repeated thermal cycling.
