BD5.1/2/4-3C90

Overview

The Ferroxcube BD5.1/2/4-3C90 is a cylindrical ferrite bead constructed from 3C90 material, designed for electromagnetic interference suppression in electronic circuits. The component features a standard cylindrical geometry with specific dimensional parameters defined by the manufacturer's nomenclature. It is supplied as an individual passive magnetic element intended for direct integration onto cables or wires to attenuate high-frequency noise signals without altering the DC current path.

Feature Summary

• Utilizes 3C90 soft ferrite material optimized for broadband noise attenuation across varying frequency ranges.
• Provides effective common-mode and differential-mode interference suppression through intrinsic magnetic impedance characteristics.
• Features a robust cylindrical form factor suitable for secure mechanical attachment to various cable diameters.

Applications

• High-frequency noise filtering on data communication cables
• Electromagnetic compatibility enhancement in consumer electronics assemblies
• Signal integrity improvement in industrial control wiring harnesses

Procurement Notes

Verify that the specified 3C90 material grade matches the target frequency spectrum requirements for the application. Confirm physical dimensions align with available cable outer diameters to ensure proper fitment. Check RoHS compliance status if environmental regulations apply to the final product assembly. Ensure storage conditions maintain material integrity prior to installation.

Selection Notes

Select this component based on the required impedance profile at the specific operating frequencies of the noisy signal lines. Evaluate the current carrying capacity of the associated cable rather than the bead itself, as the ferrite acts passively. Consider spatial constraints within the enclosure to determine if the cylindrical shape offers the most efficient layout solution compared to clip-on alternatives.

Part Context

This part belongs to the Ferroxcube family of passive magnetic components, specifically categorized under ferrite beads and rings. These elements are engineered to complement transformers and inductors by providing targeted high-frequency attenuation. The designation indicates a standardized size within the manufacturer's catalog, ensuring interchangeability with other similarly dimensioned components in existing designs.
