28R0983-000

Overview

The 28R0983-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It features an internal slot dimension of 0.827 inches wide by 0.031 inches high (21.00mm x 0.80mm). The external dimensions are 0.984 inches wide by 0.118 inches high (25.00mm x 3.00mm). The component exhibits an impedance of 123 Ohms at 100 MHz.

Feature Summary

• Solid construction design for stable electromagnetic interference suppression
• Free-hanging installation type suitable for cable wrapping applications
• Specifically engineered internal slot geometry to accommodate flat ribbon cables

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Signal integrity enhancement in data transmission lines
• Common mode noise reduction in electronic assembly wiring

Procurement Notes

Verify the specific internal slot width and height requirements against the target cable dimensions before procurement. Confirm that the solid core material composition aligns with project environmental regulations. Ensure the mounting method supports the free-hanging configuration without mechanical stress on the connected cables during operation.

Selection Notes

Select this component when dealing with flat ribbon cables requiring a 21.00mm width clearance. The 123 Ohm impedance at 100 MHz indicates suitability for specific frequency range noise filtering. Compare physical envelope constraints against available board or chassis space to ensure adequate clearance for the external dimensions.

Part Context

This part belongs to the Laird ferrite cable core family, designed for passive EMI mitigation. It serves as a passive filter element that increases impedance to high-frequency noise currents while allowing desired signal frequencies to pass with minimal attenuation. It complements active filtering solutions in complex electronic systems.

Replacement Considerations

Substitute parts must match the 21.00mm internal slot width and similar impedance characteristics. Verify that alternative manufacturers offer compatible solid core materials and free-hanging form factors to maintain mechanical fit.
