SS28B2042K

Overview

The SS28B2042K is a hinged ferrite core manufactured by Leader Tech Inc., designed for electromagnetic interference suppression on cables. It utilizes Material 28, providing an impedance of 238 Ohms at 100 MHz. The component features a box-shaped design with flexible spring flutes at the end ports to accommodate variable cable diameters. Key dimensions include an inner diameter of 0.425 inches (10.8 mm) and an external length of approximately 1.48 inches (37.6 mm).

Feature Summary

• Hinged snap-on design for easy installation around existing cables.
• Variable diameter end ports with flexible spring flutes for secure grip.
• Material 28 composition optimized for high-frequency noise suppression.

Applications

• Suppression of electromagnetic interference on wiring assemblies.
• Noise reduction in electronic equipment cabling.
• EMI filtering for signal and power lines.

Procurement Notes

Verify the specific impedance value and material grade against the official Leader Tech datasheet, as variations may exist between standard and K-tail suffixes. Confirm physical dimensions match the target cable assembly requirements before procurement. Ensure compliance with relevant environmental regulations such as RoHS if specified in the product documentation.

Selection Notes

Select this component when a hinged ferrite solution is required for retrofitting or frequent cable changes. The Material 28 specification indicates suitability for higher frequency ranges compared to lower-numbered materials. The spring-loaded design accommodates slight variations in cable diameter, making it versatile for multi-cable bundles or varying wire gauges within the specified inner diameter range.

Part Context

Leader Tech Inc. specializes in EMI shielding products, including ferrite cores for circuit boards and interconnect cables. The SS series represents their line of clamp-on ferrites, which are widely used in industrial and commercial electronics for noise control. This part belongs to the FerriShield family, known for robust mechanical designs that protect sensitive signals from radiated and conducted interference.

Replacement Considerations

Direct substitutes should be sought among other Leader Tech hinged ferrites with similar Material 28 characteristics and comparable inner diameters. Cross-brand replacements must match the 238 Ohm @ 100MHz impedance profile and physical mounting constraints. Verify that alternative components offer equivalent spring tension and durability for long-term reliability.
