BD8/1.5/10-4S2

Overview

The Ferroxcube BD8/1.5/10-4S2 is a cylindrical ferrite bead designed for high-frequency noise suppression in electronic circuits. It features a single-line configuration with an impedance of 181 Ohms at 100 MHz. The component measures 8 mm in diameter, 1.5 mm in width, and 10 mm in length. It is supplied in bulk packaging and supports free-hanging installation. The part complies with RoHS3 standards and carries an EAR99 classification.

Feature Summary

• Provides significant impedance to attenuate high-frequency electromagnetic interference signals
• Cylindrical geometry allows for flexible mounting orientations on printed circuit boards
• Single-line design simplifies integration into power and signal lines

Applications

• High-frequency noise filtering in power supply input stages
• Signal line protection against radio frequency interference
• Common mode noise suppression in data transmission cables

Procurement Notes

Verify the specific suffix '4S2' corresponds to the required impedance tolerance and material grade. Confirm that the bulk packaging format aligns with your assembly equipment capabilities. Ensure the physical dimensions fit within the designated footprint on the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when a compact cylindrical form factor is required for space-constrained designs. The 181 Ohm impedance at 100 MHz makes it suitable for suppressing noise in the VHF range. Consider the thermal characteristics and current handling limits relative to the specific application environment to ensure reliable long-term operation.

Part Context

This part belongs to the Ferroxcube ferrite bead family, which offers various shapes and sizes for EMI suppression. The BD series specifically denotes cylindrical beads. These components are passive magnetic devices used to dissipate high-frequency energy as heat, protecting sensitive electronics from conducted interference without affecting low-frequency or DC signals.

Replacement Considerations

Cross-reference with other cylindrical ferrite beads offering similar 181 Ohm impedance at 100 MHz. Verify dimensional compatibility, particularly the 8mm diameter and 10mm length, to ensure mechanical fit. Check if alternative materials provide comparable performance at higher operating temperatures.
