ZCAT1730-0730A

Overview

The TDK ZCAT1730-0730A is a round ferrite clamp-on core designed for USB cable filtering. It features an internal diameter of 7.1 mm and external dimensions of 16.5 mm by 23 mm. The component operates within a temperature range of -40°C to +85°C. Impedance values are specified as 40 ohms at 25 MHz, 40 ohms at 50 MHz, 80 ohms at 100 MHz, 80 ohms at 300 MHz, and 80 ohms at 500 MHz. It utilizes TDK's Material 30 ferrite composition.

Feature Summary

• Snap-fit design allows one-touch attachment to cables without disconnection
• Round geometry provides uniform magnetic flux distribution around the conductor
• Integrated plastic housing protects the ferrite material and ensures secure clamping

Applications

• USB interface cable EMI suppression
• Power cable noise reduction in electronic equipment
• Signal integrity enhancement for high-speed data lines

Procurement Notes

Verify the specific impedance profile against your target frequency requirements, as values vary across the spectrum. Confirm compliance with RoHS and REACH directives if required by your region. Ensure the cable diameter falls within the 4mm to 7mm range for proper fit. Check for any specific packaging quantities or handling instructions provided by the distributor.

Selection Notes

Select this model when a non-invasive, snap-on solution is preferred over split-core assemblies requiring tools. The 7mm inner diameter accommodates standard USB cables. Consider the operating temperature range of -40°C to +85°C for environmental suitability. Compare impedance characteristics at critical frequencies against other ZCAT series variants to ensure adequate attenuation for your specific noise profile.

Part Context

This component belongs to the TDK ZCAT series of clamp-on ferrite cores. These components are engineered for easy installation on existing cable assemblies. The ZCAT1730-0730A specifically targets applications requiring moderate impedance levels across a broad frequency range, balancing performance with mechanical ease of use for mass production environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative ferrite materials if supply constraints exist, ensuring similar impedance curves and physical dimensions.
