28B0384-000

Overview

The 28B0384-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products, designed for cable and wiring applications. It exhibits an impedance of 159 Ohms at 100 MHz. The component features a circular design with an inner diameter of 0.150 inches (3.80 mm), an outer diameter of 0.384 inches (9.75 mm), and a length of 0.394 inches (10.00 mm). It utilizes Material 28 and supports surface mount or free-hanging installation types.

Feature Summary

• Solid construction for durable cable suppression
• Free-hanging mounting configuration
• Material 28 composition for specific frequency attenuation

Applications

• Cable and wiring EMI suppression
• Signal integrity enhancement in harnesses
• Common mode noise reduction on cables

Procurement Notes

Verify the exact material grade and impedance tolerance against the official Laird datasheet before integration. Confirm that the inner diameter accommodates the target cable bundle without excessive friction. Ensure the operating environment remains within standard industrial temperature ranges as specified for Material 28 components.

Selection Notes

Select this part when a solid, non-split ferrite core is required for permanent cable installations. The 3.80 mm inner diameter limits usage to smaller gauge wires or tightly bundled cables. Compare impedance characteristics against other Material 28 variants if higher attenuation at different frequencies is needed.

Part Context

This component belongs to the 28B series of cable ferrites from Laird-Signal Integrity Products. It serves as a passive electromagnetic interference filter, distinct from split cores which allow installation on existing cables. The solid design provides consistent mechanical stability and electrical performance for pre-assembled wire harnesses.

Replacement Considerations

Direct substitutes include other solid ferrite cores with matching 3.80 mm inner diameters and similar 100 MHz impedance values. Verify physical dimensions and material properties to ensure equivalent noise suppression capabilities.
