Procurement Notes
Verify the specific suffix against official Bourns documentation to confirm exact physical dimensions and packaging type. Ensure the selected variant matches the required thermal performance and lead configuration for your PCB layout. Cross-reference the datasheet for precise mechanical tolerances before finalizing procurement specifications.
Selection Notes
Select this component when a high holding current of 6.5 A is required within a low-voltage 16 V system. Consider the 15.8 mOhms initial resistance for power loss calculations. Verify that the operating environment stays within the specified -40°C to +85°C range. Ensure the radial package fits the available board space and hole pattern.
Part Context
This part belongs to the Bourns Multifuse RG series, which specializes in high-current resettable fuses. The series is characterized by its ability to handle significant fault currents while maintaining a compact form factor suitable for dense PCB layouts. It serves as a critical safety component in modern electronic designs requiring reliable overcurrent protection.
Replacement Considerations
Consult the official Bourns replacement guide for direct equivalents. Verify that any substitute maintains the same 6.5 A holding current and 16 V rating. Ensure the replacement part supports the required radial mounting style and meets the same environmental temperature specifications.
