ZCAT4625-3430D-BK

Overview

The ZCAT4625-3425-3430D-BK is a hinged ferrite clamp-on core designed for flat ribbon cables. It features a black case and operates within a temperature range of -40°C to +85°C. The component provides an impedance of 35 Ohms at frequencies between 50 MHz and 500 MHz. Internal dimensions are 34.1 mm, with external dimensions of 45.5 mm length, 24.5 mm width, and 12 mm height. It belongs to the ZCAT series and is packaged in bulk quantities.

Feature Summary

• Hinged snap-on design for easy installation on existing flat cable assemblies
• Ferrite material construction optimized for high-frequency noise suppression
• Black casing for visual identification and standard industrial aesthetics

Applications

• EMI suppression for flat ribbon cables in electronic equipment
• Noise filtering for data transmission lines operating in the 50-500 MHz range
• Cable harness management in automotive or industrial control systems

Procurement Notes

Verify the specific suffix 'BK' corresponds to the black color variant when ordering. Confirm that the 35 Ohm impedance specification aligns with the target frequency requirements of 50 MHz to 500 MHz. Ensure the internal length of 34.1 mm accommodates the thickness of the flat cable being treated. Check packaging quantity details if bulk handling is required for production lines.

Selection Notes

Select this model for applications requiring non-invasive EMI mitigation on pre-assembled flat cables. The hinged design eliminates the need to disconnect cables during installation. Consider the 35 Ohm impedance value relative to the noise spectrum; higher impedance may be needed for different frequency profiles. Verify thermal compatibility with the -40°C to +85°C operating range of the environment.

Part Context

This component is part of TDK's ZCAT series of ferrite cores. These cores are specifically engineered for clamping onto flat ribbon cables rather than round wires. The ZCAT series offers various impedance values and physical sizes to suit different cable widths and noise frequencies. This specific model targets mid-to-high frequency interference reduction.

Replacement Considerations

Direct substitutes must match the 35 Ohm impedance at 50-500 MHz and similar physical dimensions (approx. 34mm internal length). Other TDK models in the ZCAT series with compatible impedance and hinged designs may serve as alternatives. Verify that any replacement maintains the same temperature rating and flat cable compatibility.
