CST16/7.9/29-4S2

Overview

The Ferroxcube CST16/7.9/29-4S2 is a cylindrical ferrite core designed for electromagnetic interference suppression. Constructed from 4S2 material, it functions as a tubular cable shield with one hole and an internal diameter of 4.75mm. The component measures 9.5mm in external diameter and 12.7mm in length. It provides an impedance of 213 ohms at 100MHz, offering protective attenuation of radio frequency interference across a wide frequency range.

Feature Summary

• Provides protective attenuation of radio frequency interference over a wide frequency range
• Constructed from 4S2 ferrite material suitable for EMI-suppression applications
• Designed as a tubular cable shield with a single central aperture

Applications

• EMI suppression products
• Cable shielding for electronic equipment
• RFI attenuation in signal lines

Procurement Notes

Verify the specific part number CST16/7.9/29-4S2 against official Ferroxcube documentation to confirm material grade and dimensional tolerances. Ensure compatibility with cable diameters up to 4.75mm. Cross-reference impedance specifications at 100MHz with system requirements. Confirm RoHS compliance status through current manufacturer datasheets rather than distributor listings.

Selection Notes

Select this component when high-frequency RFI attenuation is required for cables fitting within a 4.75mm bore. The 4S2 material offers specific permeability characteristics distinct from other grades. Consider the physical dimensions (9.5mm x 12.7mm) for spatial constraints in assembly. Evaluate the 213 ohm impedance value against the noise spectrum of the target application.

Part Context

This component belongs to the Ferroxcube cylindrical core ferrite series, specifically engineered for cable shielding. It complements other EMI suppression solutions by providing passive attenuation without active circuitry. The designation reflects its geometric proportions and material composition, aligning with standard industrial filtering requirements.
