BF1225

Overview

The Delevan BF1225 is a split ferrite suppressor core designed for cable noise reduction. It features a hinged snap-on design allowing installation around existing cables without disconnection. The component provides an impedance of 146 Ohms at 100 MHz. It has an inner diameter of 4.00 mm and outer dimensions of 12.80 mm width by 14.70 mm height.

Feature Summary

• Hinged snap-on construction enables rapid installation on live cables
• Provides high impedance to suppress electromagnetic interference
• Free-hanging mounting style suitable for various cable configurations

Applications

• Cable noise suppression in electronic assemblies
• EMI filtering for signal and power lines
• Retroactive shielding of connected wiring harnesses

Procurement Notes

Verify the specific impedance value and physical dimensions against the latest manufacturer datasheet before integration. Confirm that the target cable diameter falls within the specified inner diameter range to ensure proper fit and effective suppression performance.

Selection Notes

Select this component when retrofitting shielding onto existing cables is required. The hinged design eliminates the need to disconnect wires during installation. Ensure the operating environment temperature remains within the specified limits for optimal magnetic material performance.

Part Context

This part belongs to the BF series of ferrite cores manufactured by Delevan. These components are categorized as cable ferrites or split suppressors. They are distinct from fixed inductors and chokes, serving primarily as passive EMI mitigation devices for wire management.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative split ferrite cores based on matching impedance curves and physical clearance constraints.
