SS33B2040

Overview

The SS33B2040 is a hinged ferrite clamp-on core manufactured by Leader Tech Inc. It utilizes material formulation 33 and provides an impedance of 27 Ohms at 30 MHz. The component features a square shape with a free-hanging design and snap-on closure mechanism. Internal dimensions include a 14 mm inside diameter, while external measurements are 31.8 mm in length, 29.33 mm in width, and 28.6 mm in height. The unit weighs approximately 96.282 grams and is packaged in bulk quantities.

Feature Summary

• Hinged snap-on design for easy installation around cables
• Square cross-section geometry optimized for specific cable profiles
• Material 33 formulation providing targeted high-frequency noise suppression

Applications

• EMI suppression on single round cables
• Signal integrity enhancement in electronic assemblies
• Noise filtering for data transmission lines

Procurement Notes

Verify the exact impedance value at 30 MHz matches system requirements. Confirm the 14 mm internal diameter accommodates the target cable bundle without excessive clearance. Ensure the square outer profile fits within available spatial constraints. Check RoHS compliance status if required by project specifications. Validate that the hinged mechanism remains secure during operation.

Selection Notes

Select this component when a snap-on ferrite is preferred over split-bead styles for repeated access. Choose Material 33 for applications requiring effective attenuation in the VHF range. Ensure the 14 mm bore size aligns with the maximum cable diameter to be treated. Consider the square shape for better contact surface area compared to circular cores of similar inner dimensions.

Part Context

This part belongs to the FerriShield line of cable ferrites from Leader Tech Inc. It is designed as a clamp-on solution for EMI shielding. The product series includes various sizes and materials tailored for different frequency ranges and cable diameters. The SS33B2040 specifically targets mid-range frequencies using standard nickel-zinc formulations.

Replacement Considerations

Direct substitutes may include other hinged ferrites with identical 14 mm ID and 27 Ohm @ 30MHz impedance. Verify physical dimensions match if space is constrained. Alternative materials may offer different impedance curves but require re-validation of noise suppression performance.
