MF-RHT300-2-14

Overview

The Bourns MF-RHT300-2-14 is a high-temperature polymeric positive temperature coefficient (PPTC) resettable fuse designed for radial leaded PCB mounting. It features a hold current of 3.0 A and a trip current of 6.0 A, with a maximum voltage rating of 16 VDC. The device offers a maximum fault current capacity of 100 A and an initial resistance of 79 mΩ. It operates within a temperature range of -40°C to +125°C and has a lead spacing of 5.1 mm. This component is AEC-Q200 qualified for automotive reliability.

Feature Summary

Provides automatic circuit protection against overcurrent conditions through self-resetting functionality.
Engineered for high-temperature environments with stable performance up to 125°C.
Radial leaded construction facilitates through-hole PCB integration.

Applications

Automotive electronic circuits requiring AEC-Q200 compliance
High-temperature industrial control systems
Consumer electronics power input protection

Procurement Notes

Verify the specific suffix '-14' corresponds to the cut tape packaging configuration as indicated in distributor records. Confirm that the AEC-Q200 qualification status is maintained for the specific manufacturing lot. Ensure the radial lead spacing matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage (16V) PTC fuse is required for high-current applications up to 3A hold current. The high-temperature rating makes it suitable for enclosed or high-heat environments where standard PTCs might fail. Verify that the 100A maximum fault current rating exceeds the potential short-circuit currents in the target circuit design.

Part Context

This part belongs to the Bourns MF-RHT series of high-temperature PTC resettable fuses. The series is characterized by its ability to withstand elevated operating temperatures compared to standard polymeric fuses. The MF-RHT300-2-14 specifically denotes the 3.0A hold current variant within this high-reliability family.

Replacement Considerations

Direct substitutes within the same series include the MF-RHT300-AP-14 and MF-RHT300-0-14. These variants share similar electrical characteristics but may differ in packaging or specific material compositions. Verify compatibility with existing thermal management designs when swapping between these specific model numbers.
