ZCAT2017-0930B-BK

Overview

The TDK ZCAT2017-0930B-BK is a split-core ferrite clamp filter designed for suppressing electromagnetic interference on cables. It features a round case with an inner diameter of 9 mm and an outer diameter of 17 mm, accommodating cables up to 9 mm in diameter. The component operates within a temperature range of -40°C to +85°C. It provides an impedance of 20 Ω at frequencies between 10 MHz and 100 MHz, and 50 Ω from 100 MHz to 500 MHz. The unit weighs approximately 12 grams and is constructed from ferrite material housed in a black case.

Feature Summary

• Split-core design allows installation onto existing cables without disconnection
• Round case structure accommodates circular cable types
• Ferrite core material provides effective noise suppression across specified frequency bands

Applications

• Electromagnetic interference suppression in industrial control systems
• Noise reduction for signal lines in medical electronic equipment
• EMI mitigation in automotive wiring harnesses

Procurement Notes

Verify the specific suffix B-BK against official TDK documentation to confirm case color and exact dimensional tolerances. Ensure the selected variant matches the required cable diameter of up to 9 mm. Confirm RoHS compliance status through the manufacturer's current datasheet before integration into regulated products.

Selection Notes

Select this model when retrofitting ferrite suppression onto pre-assembled cables where clamping is necessary. The 9 mm inner diameter limits usage to smaller gauge wires. Compare impedance characteristics against system noise profiles to ensure adequate attenuation in the 10 MHz to 500 MHz range.

Part Context

This component belongs to the TDK ZCAT series of cable-fixed ferrite cores. These devices are engineered for high-frequency noise suppression in compact spaces. The split-core mechanism distinguishes them from traditional snap-on rings, offering flexibility for post-assembly integration in complex wiring environments.

Replacement Considerations

Direct substitutes include other TDK ZCAT series models with compatible inner diameters, such as ZCAT2017-0930A-BK. Verify that alternative parts maintain identical impedance curves and operating temperature ranges to ensure equivalent performance.
