28S2022-0M0

Overview

The 28S2022-0M0 is a split ferrite cable core manufactured by Laird-Signal Integrity Products, designed for electromagnetic interference suppression. It utilizes Material 28 and provides an impedance of 250 Ohms at 100MHz. The component features a clip-together design requiring two units to form a single assembly. Key dimensions include an inner width of 34.42mm, an outer width of 45.09mm, and a length of 28.58mm. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Split design allows installation on existing cables without disconnection
• Clip-together mechanism secures the core around the conductor
• High impedance material effective for broadband noise suppression

Applications

• Suppression of common-mode noise on flat ribbon cables
• EMI filtering in high-speed digital signal lines
• Noise reduction on power supply cables in electronic assemblies

Procurement Notes

Verify that procurement quantities account for the dual-unit assembly requirement, as two cores are needed to complete one functional unit. Confirm the specific impedance tolerance and material grade match the target frequency spectrum requirements. Ensure the inner slot dimensions accommodate the maximum diameter of the cable being treated to maintain proper magnetic coupling efficiency.

Selection Notes

Select this component when retrofitting EMI suppression onto pre-assembled ribbon or multi-conductor cables. The split design is critical for applications where cable termination cannot be undone. Evaluate the 250 Ohm impedance profile against the noise frequencies present in the system. Ensure the physical size fits within the available enclosure space while allowing sufficient clearance for the clip mechanism.

Part Context

This part belongs to the 28S series of split ferrite cores from Laird-Signal Integrity Products. These components are engineered for versatile cable management and noise control. The series offers various sizes and impedance levels to suit different cable diameters and frequency ranges, providing a standardized solution for signal integrity enhancement in complex wiring harnesses.

Replacement Considerations

Direct substitutes must match the 250 Ohm @ 100MHz impedance and compatible inner slot dimensions. Verify that alternative split cores support the same clip-together mounting style. Ensure replacement parts maintain the -40°C to +125°C operating temperature range and RoHS compliance status.
