28B0385-2

Overview

The Leader Tech Inc. 28B0385-2 is a miniature solid round ferrite bead designed for cable applications. It features an inner diameter of 0.90 mm and provides an impedance of 452 Ohms at 100 MHz. The component is manufactured by Leader Tech Inc. under the FerriShield brand, intended for suppressing electromagnetic interference on small-diameter cables.

Feature Summary

• Miniature solid round ferrite construction
• High impedance performance at 100 MHz
• Designed for small diameter cable bundles

Applications

• Electromagnetic interference suppression on small cables
• Signal integrity enhancement in compact electronic assemblies
• Common mode noise reduction on data lines

Procurement Notes

Verify the exact impedance value and frequency rating against the official datasheet before integration. Confirm that the 0.90 mm inner diameter accommodates the target cable bundle without excessive force. Ensure the component meets required environmental standards for the specific deployment scenario.

Selection Notes

Select this part when space constraints require a miniature form factor. The 0.90 mm bore size limits usage to very thin cables or wire harnesses. Evaluate if the 452 Ohm impedance level matches the noise spectrum requirements of the application circuit.

Part Context

This component belongs to the Leader Tech FerriShield line of ferrite cores. It is categorized as a solid round bead, distinct from snap-on or split-core designs. The product serves as a passive filter element for high-frequency noise attenuation.
