28R2189-000

Overview

The Laird-Signal Integrity Products part number 28R2189-000 is a solid ferrite cable core designed for electromagnetic interference suppression. It features a rectangular cross-section with dimensions of 55.61mm by 50mm and a length of 14mm. The component is constructed from material suitable for broadband noise attenuation in power and signal lines.

Feature Summary

• Solid construction provides mechanical stability for cable mounting
• Rectangular geometry accommodates flat or bundled conductors
• Broadband frequency response supports diverse noise profiles

Applications

• Power supply line filtering
• Signal cable noise suppression
• Industrial equipment EMI mitigation

Procurement Notes

Verify the exact material composition and impedance characteristics against your specific frequency requirements before procurement. Confirm that the physical aperture dimensions match the target cable bundle diameter to ensure proper fit and effective magnetic coupling. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a high-volume, cost-effective solution for general-purpose EMI suppression is needed. The solid design simplifies assembly compared to split cores. Ensure the operating temperature range aligns with your system environment and that the DC current capacity does not saturate the core material.

Part Context

This ferrite core belongs to the FCCRib series from Laird-Signal Integrity Products. It is categorized under cable ferrites used for common-mode noise reduction. The product is widely distributed through electronic component distributors and is commonly specified in consumer electronics and industrial control systems for basic EMI compliance.
