MF-RX375-2-14

Overview

The MF-RX375-2-14 is a polymeric PTC resettable fuse from the Bourns MF-RX/72 series. It features a hold current of 3.75 A and a trip current of 7.5 A, with a maximum voltage rating of 60 VDC. The device has a maximum fault current rating of 40 A and a typical resistance of 50 mΩ. It operates within a temperature range of -40°C to +85°C and utilizes radial leaded termination with a 10.2 mm lead spacing.

Feature Summary

Provides automatic circuit protection through self-resetting polymeric technology
Offers high fault current capability for robust overcurrent defense
Supports through-hole PCB mounting via radial leads

Applications

Overcurrent protection in electronic circuits
Battery pack safeguarding
Peripheral device interface protection

Procurement Notes

Verify that the specific part number matches the required voltage rating of 60VDC, as similar series variants may support higher voltages like 72VDC. Confirm the hold current specification aligns with the design requirements. Ensure the radial lead pitch corresponds to the target PCB footprint dimensions before finalizing procurement orders.

Selection Notes

Select this component when a 3.75A hold current and 60VDC rating are required for through-hole applications. Consider the 40A maximum fault current capacity for surge tolerance. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +85°C range during normal and fault conditions.

Part Context

This component belongs to the MF-RX/72 series of multifuse devices manufactured by Bourns Inc. These parts are designed as alternative solutions to traditional fuses, offering resettable functionality. The series is characterized by compact radial packages suitable for space-constrained printed circuit board layouts.

Replacement Considerations

Cross-reference with MF-RX375/72-2-14 for potential voltage compatibility differences. Verify pinout and dimensional tolerances against existing designs to ensure mechanical fit without modification.
