CST14/7.3/29-3E27

Overview

The Ferroxcube CST14/7.3/29-3E27 is a tubular ferrite core designed for cable shielding applications. It utilizes the 3E27 material composition, which provides high permeability and low loss characteristics suitable for suppressing electromagnetic interference in the high-frequency range. The component features a cylindrical geometry with an internal diameter of 6.35mm, allowing it to accommodate standard cable sizes. Its external dimensions are defined by a length of 29mm and an outer diameter of 14mm. This specific part number identifies the physical size and material grade combination within the Ferroxcube product line.

Feature Summary

• Tubular design facilitates easy installation over cables without disconnection
• 3E27 material offers optimized magnetic properties for broadband noise suppression
• Fixed dimensional profile ensures compatibility with standard cable diameters

Applications

• Electromagnetic interference suppression on data cables
• Noise filtering in telecommunications equipment
• Common mode choke application for signal lines

Procurement Notes

Verify the exact material grade 3E27 against project specifications, as Ferroxcube offers multiple material compositions with distinct frequency responses. Confirm that the 6.35mm inner diameter matches the target cable bundle size to ensure proper fit. Request the official datasheet to validate impedance characteristics at relevant operating frequencies before finalizing procurement.

Selection Notes

Select this component when a tubular form factor is required for post-assembly cable protection. The 3E27 material is appropriate for applications requiring effective attenuation in the tens to hundreds of megahertz range. Ensure the physical length of 29mm fits within the available spatial constraints of the enclosure or cable routing path.

Part Context

This part belongs to the CST series of tubular ferrite cores manufactured by Ferroxcube. The naming convention indicates the outer diameter (14mm), inner diameter (7.3mm nominal, actual ID 6.35mm), and length (29mm). The suffix 3E27 specifies the manganese-zinc ferrite material formulation used for power and signal integrity applications.

Replacement Considerations

Direct substitutes must match the 14mm OD, 6.35mm ID, and 29mm length while utilizing equivalent 3E27 material properties. Verify impedance curves from alternative manufacturers to ensure comparable performance at critical frequencies.
