BF2930

Overview

The BF2930 is a split ferrite suppressor manufactured by Delevan, designed for cable-mounted electromagnetic interference suppression. It features a hinged construction with an internal diameter of 13 mm to accommodate cables. The component exhibits an impedance of 155 ohms at 100 MHz and 257 ohms at 100 MHz as per specific product descriptions. It operates within a temperature range of -20°C to +60°C and utilizes ferrite material for noise attenuation.

Feature Summary

• Hinged split design allows installation on existing cables without disconnection
• Ferrite core material provides effective high-frequency noise suppression
• Round shape accommodates standard cylindrical cable geometries

Applications

• Cable-mounted electromagnetic interference suppression
• High-frequency noise attenuation in electronic assemblies
• Signal integrity enhancement for data and power lines

Procurement Notes

Verify the exact impedance specifications against the official datasheet, as conflicting values (155 ohms vs 257 ohms) appear in available documentation. Confirm RoHS compliance status and manufacturing origin with the supplier. Ensure the 13 mm inner diameter matches the target cable size before procurement.

Selection Notes

Select this component when a non-invasive, clamp-on solution is required for cable noise reduction. The 13 mm bore size dictates compatibility with specific cable diameters. Consider the operating temperature range and physical mounting constraints relative to the application environment.

Part Context

The BF2930 belongs to the BF series of split ferrite cores from Delevan. These components are categorized as cable ferrites or suppressors, distinct from surface-mount inductors or through-hole chokes. They serve as passive filtering elements for conducted emissions control.
