Overview
The Bourns MF-R600 is a radial leaded PTC resettable fuse designed for overcurrent protection. It features a hold current of 6 A and a trip current of 12 A, with a maximum voltage rating of 30 V. The device exhibits a minimum resistance of 20 mOhms and can withstand a maximum rated current of 40 A. It operates within a temperature range of -40°C to +85°C and utilizes a 10.2 mm lead spacing.
Feature Summary
- Provides automatic circuit recovery after fault clearance without manual replacement
- Offers dual-mode protection against overcurrent and excessive heat conditions
- Constructed with radial leads for reliable through-hole PCB mounting
Applications
- LED driver applications
- Current control circuits
- Overheat protection systems
- Surge and ESD protection interfaces
Procurement Notes
Verify the specific suffix (e.g., AP) required for your assembly process, as standard listings may indicate Ammo Pack packaging. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to ordering. Ensure the selected variant matches the required lead spacing and package dimensions for your PCB layout constraints.
Selection Notes
Select this component when a 6 A hold current and 30 V maximum voltage are required for radial mounting. Evaluate the thermal environment to ensure operation remains within the -40°C to +85°C range. Consider the 20 mOhms resistance impact on power loss in low-voltage high-current paths before finalizing the design.
Part Context
This part belongs to the Multifuse series of PPTC resettable fuses manufactured by Bourns. These components utilize polymer positive temperature coefficient technology to provide reusable protection. The MF-R600 specifically addresses needs for robust, space-efficient overcurrent protection in consumer and industrial electronics requiring radial termination.
Replacement Considerations
Consult official Bourns documentation for verified substitute part numbers. Generic equivalents may not match the specific 6 A hold current or 30 V rating. Verify that any alternative maintains the same radial lead configuration and operating temperature range.
