ZCAT2035A-JW-SNBK

Overview

The TDK ZCAT2035A-JW-SNBK is a snap-on ferrite core from the ZCAT series, designed for cable electromagnetic interference suppression. It features a split design with a single opening and accommodates cables with diameters ranging from 6mm to 9mm. The component measures 19.5mm in outer width and 35mm in length. It utilizes TDK's proprietary Material 30 to deliver high impedance across critical frequency bands. Key electrical specifications include an impedance of 195Ω at 25MHz, 50Ω at 50MHz, 340Ω at 100MHz, and 100Ω at both 300MHz and 500MHz frequencies.

Feature Summary

• Snap-on split design allows for easy installation on existing cables without soldering or disassembly.
• Utilizes Material 30 composition to provide effective attenuation of common mode noise.
• Single-opening structure simplifies integration into tight spaces during EMC troubleshooting.

Applications

• Suppression of electromagnetic interference in industrial control system cabling
• Noise reduction for signal lines in medical electronic equipment
• EMI mitigation for data transmission cables in AI server infrastructure

Procurement Notes

Verify the complete part number including suffixes such as -BK or -JW-SNBK against official TDK documentation to ensure material and packaging compliance. Confirm that the supplier provides traceable origin for RoHS and REACH certified materials. Cross-reference impedance curves from the datasheet rather than relying solely on summary tables to validate performance for specific frequency requirements.

Selection Notes

Select this component when retrofitting cables with diameters between 6mm and 9mm requires non-destructive EMI filtering. The high impedance peak at 100MHz makes it suitable for suppressing noise in digital signal ranges. Ensure the application environment remains within the specified operating temperature range to maintain magnetic properties and prevent saturation under normal load conditions.

Part Context

This ferrite core belongs to the ZCAT family of cable-mounted suppressors manufactured by TDK Corporation. These components are engineered specifically for post-production EMC adjustments and initial noise design phases. The split-core architecture distinguishes them from traditional toroidal rings, offering flexibility for field applications where cables cannot be threaded through solid cores.

Replacement Considerations

Direct substitutes include other TDK ZCAT series parts with compatible inner diameters and Material 30 composition. Verify dimensional compatibility for the target cable size before swapping. Alternative manufacturers may offer similar snap-on cores, but impedance characteristics will differ significantly due to varying magnetic material formulations.
