ZCAT2235-1030A-BK

Overview

The TDK ZCAT2235-1030A-BK is a black, split-core ferrite clamp filter designed for suppressing electromagnetic interference on cables. It features a hinged case structure allowing installation without disconnecting wires. The component has an outer diameter of 21.5 mm and a length of 35 mm, with an inner diameter accommodating cables from 8 mm to 10 mm. It utilizes TDK's Material 30 ferrite composition. The impedance is specified as a minimum of 50 Ω in the 10–100 MHz range and 100 Ω in the 100–500 MHz range. The operating temperature range extends from -40°C to +85°C.

Feature Summary

• Hinged clamp-on design enables rapid installation on existing cable assemblies without requiring wire disconnection or terminal re-crimping.
• Integrated ferrite core mounted within a protective plastic case provides structural stability and consistent noise suppression performance.
• Material 30 ferrite composition offers high impedance characteristics across critical frequency bands for effective EMI attenuation.

Applications

• Electromagnetic compatibility (EMC)整改 for industrial control systems
• Noise suppression in power supply output lines
• Signal line filtering in communication equipment
• EMI mitigation in automotive wiring harnesses

Procurement Notes

Verify that the specific part number suffix matches the required color and material specifications. Confirm that the inner diameter tolerance aligns with the target cable bundle size to ensure proper clamping force. Check for RoHS and REACH compliance documentation if required by local regulations. Ensure storage conditions maintain the integrity of the plastic housing and ferrite material before assembly.

Selection Notes

Select this component when post-assembly EMC testing reveals high-frequency radiation issues that cannot be resolved through PCB layout changes. Choose based on the maximum cable diameter to ensure the clamp closes securely. Consider the impedance profile at the specific noise frequencies of interest rather than relying solely on general category ratings. Evaluate the physical space constraints around the cable routing path.

Part Context

This model belongs to the ZCAT series of fixed cable clamp filters manufactured by TDK Corporation. These components are engineered for applications where traditional snap-on cores are impractical due to pre-existing cable terminations. The series provides a standardized solution for integrating ferrite noise suppression into finished products without modifying the underlying wiring infrastructure.

Replacement Considerations

Direct substitutes include models with identical dimensions and impedance profiles such as ZCAT2235-1030A. Verify that any replacement maintains the same Material 30 specification and hinged case design to ensure equivalent mechanical fit and electrical performance.

FAQ
