ZCAT2017-0930-BK

Overview

The TDK ZCAT2017-0930-BK is a split-core ferrite clamp filter designed for electromagnetic interference suppression on cables. It features a black plastic case with an internal diameter of 9mm, accommodating round or flat cables up to this maximum diameter. The component measures approximately 30mm in length and operates within a temperature range of -40°C to +85°C. It provides impedance characteristics suitable for noise reduction in the MHz frequency spectrum, offering a convenient snap-on installation method without requiring soldering.

Feature Summary

• Split-core design allows for easy installation onto existing cables without disconnection
• Black plastic housing protects the ferrite core and ensures secure clamping
• Suitable for both round and flat cable geometries up to 9mm diameter

Applications

• Electromagnetic interference suppression in industrial control systems
• Noise filtering for signal and power cables in automotive electronics
• EMI mitigation in consumer electronic device cabling

Procurement Notes

Verify that the specific part number matches the required cable diameter of 9mm maximum. Confirm the operating temperature range requirements align with the -40°C to +85°C specification. Ensure the application environment does not require AEC-Q200 automotive qualification, as this model is not certified under that standard. Check for any specific packaging quantity requirements if bulk ordering is planned.

Selection Notes

Select this component when a non-invasive solution for adding ferrite impedance to existing wiring harnesses is required. The 9mm inner diameter limits its use to smaller gauge cables; larger cables require different series models. Consider the mechanical retention strength of the plastic clip for vibration-prone environments. This type is ideal for retrofitting or prototyping where permanent mounting is not feasible.

Part Context

This component belongs to TDK's ZCAT series of clamp filters, which are widely used for EMC compliance. Unlike solid cores, these split designs offer flexibility for post-manufacturing installation. The 'BK' suffix typically denotes the black color of the plastic casing. It serves as a passive component to attenuate high-frequency common-mode noise on cables.

Replacement Considerations

Direct substitutes may include other TDK split-core ferrites with similar 9mm inner diameters, such as the ZCAT2017-0930 (without BK suffix if color is irrelevant). Cross-brand equivalents must match the 9mm ID and comparable impedance curves at target frequencies. Verify that alternative parts meet the same -40°C to +85°C operating temperature range.
