28R1022-000

Overview

The Laird-Signal Integrity Products 28R1022-000 is a solid, free-hanging ferrite core designed for cable filtering applications. It belongs to the 28R series and utilizes Material 28 composition. The component exhibits an impedance of 91 Ohms at 100MHz. Its physical dimensions include an inner slot size of 0.866 inches wide by 0.047 inches high (22.00mm x 1.20mm) and an outer dimension of 1.024 inches wide by 0.197 inches high (26.00mm x 5.00mm). The total length is 0.354 inches (9.00mm).

Feature Summary

• Solid construction with free-hanging installation type for flexible cable integration.
• Utilizes Material 28 composition to provide effective electromagnetic interference suppression.
• Flat profile design accommodates ribbon cables or flat wiring harnesses.

Applications

• Suppression of common-mode noise on flat ribbon cables.
• EMI filtering for internal wiring in electronic enclosures.
• Signal integrity enhancement for data transmission lines.

Procurement Notes

Verify the specific material grade and impedance tolerance against the official datasheet before finalizing procurement. Confirm that the inner slot dimensions are compatible with the target cable geometry to ensure proper fit. Check RoHS compliance status as required by project specifications. Ensure storage conditions do not compromise the ferrite material properties prior to assembly.

Selection Notes

Select this component when filtering flat cables requiring a 91 Ohm impedance at 100MHz. The Material 28 formulation offers specific permeability characteristics suitable for general EMI suppression. Ensure the available inner slot width matches the cable thickness to allow secure sliding onto the wire without excessive force or loose fitting.

Part Context

This part is part of the Laird 28R series of cable ferrites. It serves as a passive component for noise reduction in signal and power lines. The product is manufactured by Laird-Signal Integrity Products, a provider of signal integrity solutions. It is distinct from bead types or snap-on cores due to its solid, open-slot design tailored for flat conductors.

Replacement Considerations

Direct substitutes may include other Material 28 flat ferrite cores with similar impedance profiles. Verify dimensional compatibility, particularly the inner slot width and height, to ensure mechanical fit. Cross-reference impedance curves to confirm equivalent performance at the operating frequency.
