28B0736-0

Overview

The Leader Tech Inc. 28B0736-0 is a solid round ferrite bead designed for electromagnetic interference suppression. It features an inner diameter of 10.9 mm, an outer diameter of 18.7 mm, and an external height of 33.7 mm. The component exhibits an impedance of 176 Ohms at a test frequency of 100 MHz. It is classified as a large bead type within the ferrite toroids category.

Feature Summary

• Solid cylindrical construction for durable cable clamping
• High impedance performance at 100 MHz for effective noise attenuation
• Adhesive-free design suitable for general-purpose wire wrapping

Applications

• Suppression of common-mode noise on power cables
• Filtering high-frequency interference in data transmission lines
• EMI reduction in industrial control wiring harnesses

Procurement Notes

Verify the specific impedance value of 176 Ohms at 100 MHz against your circuit requirements. Confirm that the 10.9 mm inner diameter accommodates the target cable bundle without excessive strain. Ensure the bulk packaging format aligns with your assembly handling capabilities. Cross-reference the manufacturer part number to avoid confusion with similar series items.

Selection Notes

Select this component when a robust, non-split ferrite core is required for permanent installation on wires. The solid design offers superior mechanical stability compared to split cores. Consider the physical dimensions to ensure adequate clearance within the enclosure. Evaluate the impedance curve if operation occurs significantly outside the 100 MHz test frequency.

Part Context

This part belongs to the LeaderTech Ferrishield line of solid ferrite beads. It serves as a passive component for EMI/RFI mitigation. The product falls under the broader category of ferrites and magnetic materials used in electronic circuit protection and signal integrity enhancement.

Replacement Considerations

Check for direct substitutes within the same LeaderTech series that match the 10.9 mm ID and 176 Ohm impedance. Verify dimensional compatibility before swapping manufacturers. No alternative part numbers are explicitly confirmed in the provided documentation.
