ZCAT2032-0930-BK

Overview

The TDK ZCAT2032-0930-BK is a round, snap-on ferrite clamp filter designed for cable EMI suppression. It features a unique plastic case with a self-holding mechanism to prevent slippage during installation on finished cables. The component has an inner diameter of 9 mm and outer dimensions of 36 mm length by 32 mm width. It provides a minimum impedance of 50 Ω in the 10 MHz to 100 MHz range and 100 Ω in the 100 MHz to 500 MHz range. The operating temperature range spans from -40°C to +85°C.

Feature Summary

• Snap-on design allows convenient installation on existing cable assemblies without cutting or stripping wires.
• Self-holding plastic case prevents slippage and ensures secure attachment to round cables.
• Effective attenuation of common-mode noise across high-frequency bands from 10 MHz to 500 MHz.

Applications

• Suppression of electromagnetic interference in power supply cables
• Noise reduction for communication data lines
• EMI mitigation in servo motor wiring
• Filtering control lines in photovoltaic inverters

Procurement Notes

Verify that the specific suffix '-BK' corresponds to the black color variant if color coding is critical for your assembly process. Confirm that the physical dimensions (36mm x 32mm x 9mm) match the available space in your enclosure. Ensure the target cable diameter does not exceed the 9 mm inner diameter specification to guarantee proper fit and magnetic coupling efficiency.

Selection Notes

Select this component when retrofitting EMC filters onto pre-assembled harnesses where disassembly is impractical. The snap-on mechanism offers faster production line integration compared to split-core designs requiring screws or adhesives. Consider the impedance profile requirements; this model targets frequencies above 10 MHz, making it suitable for switching noise rather than low-frequency interference.

Part Context

This part belongs to the TDK ZCAT series of clamp-on ferrite cores. These components are engineered for rapid deployment on wire bundles to suppress radiated emissions. The ZCAT series utilizes specialized ferrite materials optimized for high-frequency absorption, providing a cost-effective solution for meeting EMC compliance standards in industrial and consumer electronics.

Replacement Considerations

Direct substitutes include other TDK ZCAT series models with compatible inner diameters and impedance curves. Verify that any replacement maintains the same mechanical locking mechanism to ensure vibration resistance. Cross-reference dimensional constraints to ensure the alternative fits within the designated cable routing area.

FAQ

Does this filter handle differential mode noise?

No, ferrite clamps like the ZCAT2032-0930-BK are designed primarily to suppress common-mode noise. They do not effectively eliminate differential mode interference.

Can this clamp be reused after removal?

Yes, the self-holding mechanism allows for removal and reinstallation on different cables or for maintenance purposes without damaging the housing.
