28S2012-000

Overview

The 28S2012-000 is a split ferrite core manufactured by Laird-Signal Integrity Products, designed for cable and wire applications. It features a clip-together assembly mechanism where two pieces form one unit. The component provides an impedance of 240 Ohms at 100 MHz. Key physical dimensions include an inner diameter of 7.87 mm (0.310 inches) and an outer diameter of 20.12 mm (0.792 inches). The length of each individual half-core is 12.70 mm (0.500 inches). The material composition corresponds to the standard 28 series ferrite formulation used in this product line.

Feature Summary

• Split design with clip-together assembly for easy installation on existing cables
• High impedance performance effective for electromagnetic interference suppression
• Solid construction suitable for free-hanging mounting configurations

Applications

• Suppression of electromagnetic interference on data cables
• Noise filtering on power supply lines
• Signal integrity enhancement in communication wiring

Procurement Notes

Verify that the order quantity accounts for the assembly requirement, as two units are needed to complete one functional assembly. Confirm the specific impedance rating matches the target noise frequency spectrum. Ensure the cable diameter falls within the specified inner diameter tolerance for proper fit. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a non-invasive solution for adding ferrite suppression to existing cabling is required. The split design allows installation without disconnecting or cutting wires. Consider the 240 Ohm impedance value relative to the noise frequencies present in the application. Ensure the physical size accommodates the cable bundle diameter and available space constraints.

Part Context

This part belongs to the 28B/28S series of cable ferrites from Laird-Signal Integrity Products. These components are engineered for broadband noise suppression across various electronic systems. The split variant specifically addresses scenarios where post-assembly integration is necessary, distinguishing it from solid core alternatives that require wire threading during manufacturing.
