SA33B4340

Overview

The SA33B4340 is a hinged snap-on ferrite core designed for flat ribbon cables. It features an inside length of 82.3 mm and an outside length of 113.3 mm, with a total clamp length of 46.50 mm. The component utilizes material grade 33 and offers an impedance of 79 Ohms at 30 MHz. It is constructed as a free-hanging unit intended for cable ferrite suppression applications.

Feature Summary

• Hinged snap-on design allows for easy installation onto existing cables without disconnection.
• Utilizes ferrite material grade 33 to provide effective electromagnetic interference suppression.
• Specifically engineered for flat ribbon cable geometries.

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Cable ferrite clamping in electronic assemblies
• EMI mitigation in signal transmission lines

Procurement Notes

Verify the specific ferrite material grade and impedance characteristics against your system requirements before procurement. Confirm that the physical dimensions of the flat ribbon cable are compatible with the internal aperture of the SA33B4340 core. Ensure the hinged mechanism functions correctly for the intended mounting orientation. Cross-reference the manufacturer's datasheet for any updates regarding material composition or environmental ratings.

Selection Notes

Select this component when dealing with flat ribbon cables requiring snap-on EMI suppression. The choice depends on matching the cable width to the core's internal dimensions. Consider the operating frequency range where the 79 Ohm impedance at 30 MHz provides adequate attenuation. Evaluate the mechanical stability required for the free-hanging application to ensure the hinged design remains secure during operation.

Part Context

This component belongs to the LeaderTech cable ferrites category, specifically within their snap-on core lineup. It serves as a passive EMI suppression device distinct from through-hole or surface-mount filters. The product line focuses on providing flexible shielding solutions for various cable types, including round and flat configurations, to meet regulatory compliance standards.

Replacement Considerations

Check for direct substitutes within the same series that may offer different impedance values or material grades. Verify compatibility with alternative flat cable widths if the original specification changes. Ensure any replacement maintains the snap-on hinged design for equivalent ease of installation.
