MF-R250-2-10

Overview

The Bourns MF-R250-2-10 is a radial leaded polymeric positive temperature coefficient (PPTC) resettable fuse from the MF-R series. It features a hold current of 2.5 A and a trip current of 5 A at a maximum voltage of 30 V. The device has a typical resistance of 48 mΩ and operates within a temperature range of -40°C to +85°C. With a lead spacing of 5.1 mm and dimensions of 12 x 3 x 18.3 mm, it is designed for PCB mounting in uncoated form.

Feature Summary

Provides automatic circuit protection through reversible tripping action upon overcurrent conditions
Utilizes polymeric PTC technology for reliable thermal response without permanent damage
Features radial leads for straightforward through-hole PCB integration

Applications

Automotive electronic circuits requiring overcurrent protection
Portable consumer electronics power lines
Industrial control system signal and power paths

Procurement Notes

Verify the specific suffix '-2-10' against official Bourns documentation to confirm packaging format and lead configuration. Ensure the required hold and trip currents align with your circuit design parameters before procurement. Cross-reference the RoHS compliance status with the latest manufacturer datasheet to meet regulatory requirements.

Selection Notes

Select this component when a 2.5 A hold current and 30 V maximum rating are required for radial mounting applications. Consider the 48 mΩ resistance impact on voltage drop and the 5.1 mm lead spacing for board layout compatibility. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +85°C range for optimal performance.

Part Context

This part belongs to the Bourns MF-R series of multifuse resettable fuses. These devices are engineered for compact electronic designs where space constraints and repeated fault recovery are critical. The series offers various current ratings and package options to suit diverse protection needs across multiple industries.
