ZCAT20D

Overview

The TDK ZCAT20D is a snap-on ferrite clamp core designed for electromagnetic interference suppression. It features a hinged design with dimensions of 35.00mm length, 30.00mm width, and 20.00mm height. The inner aperture measures 15.00mm by 5.00mm. The component operates within a temperature range of -40°C to +85°C. It exhibits an impedance characteristic of 60Ω across the frequency band from 10MHz to 100MHz.

Feature Summary

• Hinged snap-on design allows installation without disconnecting cables
• Gray case construction suitable for free hanging mounting
• Optimized impedance profile for high-frequency noise attenuation

Applications

• Electromagnetic compatibility absorption in electronic assemblies
• Cable noise suppression in industrial equipment
• Signal integrity enhancement in data transmission lines

Procurement Notes

Verify the specific material composition and detailed impedance curves against official TDK datasheets before integration. Confirm that the inner aperture dimensions accommodate the target cable bundle diameter with appropriate clearance. Ensure environmental ratings meet the operational temperature requirements of the final assembly.

Selection Notes

Select this component when non-invasive cable treatment is required for EMI reduction. The rectangular cross-section accommodates flat or bundled cables effectively. Verify that the 60Ω impedance at 10-100MHz aligns with the noise spectrum of the application. Consider the physical size constraints relative to the available mounting space.

Part Context

This component belongs to the TDK ZCAT series of clamp-on ferrite cores. These products are engineered for post-production EMC improvements. The series offers various sizes and materials to address different frequency ranges and cable diameters. The ZCAT20D represents a specific geometry optimized for moderate-sized cable bundles.

Replacement Considerations

Cross-reference with other ZCAT series variants if dimensional changes are permissible. Verify impedance characteristics match the original design intent. No direct substitute part numbers are confirmed in the provided documentation.
