MF-RX012/250-2-0

Overview

The MF-RX012/250-2-0 is a radial leaded PTC resettable fuse from the Bourns Multifuse RX series. It features a hold current of 120 mA and a trip current of 250 mA, designed for circuits operating at a maximum voltage of 60 VDC. The device has a maximum resistance of 9 ohms and a rated current of 3 A. It operates within a temperature range of -40°C to +85°C and utilizes a 5.1 mm lead spacing.

Feature Summary

Provides automatic circuit protection against overcurrent conditions through self-resetting functionality
Utilizes polymeric positive temperature coefficient technology for reliable thermal response
Designed for PCB mounting with radial leads for standard through-hole integration

Applications

Overcurrent protection in consumer electronics power supplies
Signal line protection in telecommunications equipment
Circuit safeguarding in automotive electronic modules

Procurement Notes

Verify component authenticity by checking manufacturer markings and datasheet alignment. Confirm RoHS compliance status as indicated in official documentation. Ensure storage conditions maintain integrity prior to assembly. Validate lead form and spacing against PCB layout requirements before procurement finalization.

Selection Notes

Select this component when a 120 mA hold current and 60 VDC rating match circuit requirements. Consider the 9 ohm initial resistance impact on signal integrity. Evaluate thermal derating curves for high ambient temperature environments. Compare physical dimensions against available board space constraints.

Part Context

This part belongs to the Bourns Multifuse RX series, which offers radial leaded PTC fuses for general-purpose circuit protection. The series provides various hold current options to suit different amperage needs while maintaining consistent voltage ratings and package styles for standardized design implementation across product lines.

Replacement Considerations

Direct substitutes include MF-RX012/250-0 and MF-RX012/250U-A5-0 from the same manufacturer. Verify identical electrical parameters such as hold current, trip current, and voltage rating before substitution. Ensure mechanical compatibility regarding lead spacing and package dimensions.
