SS25B2040

Overview

The SS25B2040 is a square ferrite clamp-on core manufactured by Leader Tech Inc. It features a snap-on design with internal flutes to grip cables ranging from 12.7 mm to 14.0 mm in diameter. The component has an outside length of 31.8 mm, an outside width of 29.33 mm, and an outside height of 28.6 mm. It provides an impedance of 510 Ohms at 700 MHz, offering effective EMI suppression from 100 MHz to 1 GHz.

Feature Summary

• Snap-on hinged design with internal flutes for secure cable retention
• Square box sleeve shape optimized for flat or round cable shielding
• Frequency-specific ferrite formulation targeting high-frequency noise attenuation

Applications

• Suppression of electromagnetic interference on single cables
• Shielding of data and power lines in electronic assemblies
• EMI mitigation in communication equipment cabling

Procurement Notes

Verify the specific part number suffix against official Leader Tech documentation to confirm material grade and dimensional tolerances. Ensure the selected variant matches the required cable diameter range and impedance specifications for your application. Confirm RoHS compliance status through the manufacturer's current product declarations before procurement.

Selection Notes

Select this component when a snap-on ferrite solution is required for cables between 12.7 mm and 14.0 mm in diameter. The SS25B2040 is suitable for applications needing 510 Ohm impedance at 700 MHz. Consider the square profile for space-constrained environments where standard cylindrical cores may not fit. Verify that the operating frequency range aligns with the noise spectrum present in the system.

Part Context

This component belongs to the Leader Tech Ferrite Clamp On Cores category, specifically within the SS series designed for cable shielding. It is part of the FerriShield product line, which offers various formulations for different frequency ranges. The SS25B2040 shares physical mounting characteristics with other snap-on cores in the series but differs in magnetic material properties and impedance performance.

Replacement Considerations

Cross-reference with AS25B2040 if adhesive mounting is preferred over free-hanging installation. Verify compatibility with SS25B2032 or SS25B2037 only if cable diameter and impedance requirements differ significantly. Consult official substitution guides for equivalent impedance profiles.
