ZCAT1325A-JW-SNBK

Overview

The TDK ZCAT1325A-JW-SNBK is a split ferrite core clamp designed for electromagnetic interference suppression. It features a round shape with an internal diameter of 5.1 mm and an external diameter of 12.8 mm. The component has an internal length of 20 mm and operates within a temperature range of -40°C to +85°C. It provides an impedance of 50Ω at 100 MHz, making it suitable for filtering noise on cables up to 5mm in diameter.

Feature Summary

• Split design allows installation around existing cables without disconnection
• Round geometry accommodates various cable shapes
• Ferrite material construction for effective high-frequency noise attenuation

Applications

• Suppression of electromagnetic interference on USB cables
• Noise filtering for automotive wiring harnesses
• EMI reduction on industrial control signal lines

Procurement Notes

Verify the specific suffix 'SNBK' against official TDK documentation to confirm color and packaging details. Ensure the internal diameter requirement matches the target cable size of approximately 5.1 mm. Confirm compliance with RoHS standards and check for any specific handling instructions regarding the split mechanism integrity during installation.

Selection Notes

Select this component when retrofitting EMI suppression onto finished assemblies where through-hole mounting is not feasible. The 5.1 mm inner diameter limits usage to smaller gauge cables. Consider the 50Ω impedance characteristic at 100 MHz to ensure compatibility with the targeted noise frequency spectrum. Verify that the operating temperature range meets the environmental conditions of the final application.

Part Context

This part belongs to the TDK ZCAT series of clip-on ferrite cores. These components are engineered for easy integration into cable assemblies. The ZCAT series is widely used in consumer electronics and automotive applications for common mode noise suppression. The specific model indicates a standard black finish and snap-fit closure mechanism.

Replacement Considerations

Cross-reference with other TDK ZCAT models sharing the same 5.1 mm inner diameter and 20 mm length. Verify that alternative parts maintain the 50Ω impedance at 100 MHz. Ensure mechanical fitment compatibility with the available space constraints in the assembly.
