Overview
The Bourns MF-R600-2-99 is a PPTC resettable fuse from the MF-R series, designed for load protection in low-voltage power supply circuits. It features radial leads and cured flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements. The component operates within a temperature range of -40°C to +85°C. Key electrical parameters include a hold current of 6 A, trip current of 12 A, maximum voltage of 30 V, and maximum rated current of 40 A. The typical resistance is 20 mOhms, with a lead spacing of 10.2 mm.
Feature Summary
- Provides automatic circuit protection against overcurrent conditions through positive temperature coefficient behavior.
- Encased in cured flame-retardant epoxy polymer insulation compliant with UL 94V-0 standards.
- Utilizes radial leaded construction for reliable PCB mounting applications.
Applications
- Low-voltage power supply load protection
- Computer and peripheral circuit safeguarding
- General electronics equipment protection
Procurement Notes
Verify the specific suffix designation when ordering, as packaging formats such as Ammo Pack or Reel may vary by manufacturer part number variant. Confirm RoHS compliance status via the official datasheet prior to integration. Ensure the selected variant matches the required hold current and voltage ratings for the target application circuit design specifications.
Selection Notes
Select this component based on the required 6 A hold current and 30 V maximum voltage rating for the protected circuit. Consider the 20 mOhms resistance value for impact on circuit efficiency. Verify that the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the final assembly. Ensure adequate clearance for the 10.2 mm lead spacing during PCB layout.
Part Context
This device belongs to the Bourns MF-R Multifuse series of PTC resettable fuses. These components are engineered to provide reusable overcurrent protection across various electronic sectors. The series is characterized by its robust epoxy encapsulation and radial lead configuration, distinguishing it from surface-mount alternatives within the broader product portfolio.
Replacement Considerations
Direct substitutes within the same series include variants with different current ratings, such as the MF-R600-AP. Cross-series replacements require matching hold current, trip current, and voltage specifications to ensure equivalent circuit protection performance without redesigning the PCB footprint.
