BF1835-9

Overview

The Delevan BF1835-9 is a hinged, split ferrite core designed for cable electromagnetic interference suppression. It features an internal diameter of 9.00 mm and exhibits an impedance of 174 Ohms at 100 MHz. Constructed from API-1 material, this round component measures 18.60 mm in outside diameter and 35.05 mm in length. The snap-on design allows for free-hanging installation on cables without disconnection.

Feature Summary

• Hinged snap-on design enables installation on existing cables without disconnecting conductors
• Split construction facilitates easy mounting around round cables
• API-1 ferrite material provides specific high-frequency noise attenuation characteristics

Applications

• Suppression of electromagnetic interference on round cables
• Cable assembly noise filtering in electronic equipment
• High-frequency signal integrity maintenance in wiring harnesses

Procurement Notes

Verify the exact part number BF1835-9 against manufacturer documentation to ensure correct impedance and dimensional specifications. Confirm RoHS compliance status and material composition (API-1) prior to procurement. Check for any specific handling requirements associated with split ferrite cores during assembly processes.

Selection Notes

Select this component when a non-invasive cable filtering solution is required for round wires up to 9 mm diameter. The hinged design is critical for applications where cable disconnection is impractical or prohibited. Ensure the operating frequency range aligns with the 174 Ohm impedance specification at 100 MHz for effective noise suppression.

Part Context

This component belongs to the BF series of ferrite clamp-on cores manufactured by Delevan. These cores are engineered for EMI suppression in various electronic assemblies. The BF1835-9 variant specifically targets cables with a 9 mm inner diameter, offering a balance between physical size and noise attenuation performance.

Replacement Considerations

Direct substitutes must match the 9 mm inner diameter, 174 Ohm impedance at 100 MHz, and hinged design. Verify that alternative parts utilize compatible ferrite materials such as API-1 to maintain equivalent high-frequency performance characteristics.
