TX20/10/7-3N2

Ferrite Cable Overview

The Ferroxcube TX20/10/7-3N2 is a toroidal ferrite core belonging to the TX series, characterized by epoxy coating and MnZn material composition. Its physical dimensions are defined by an outer diameter of 20 mm, an inner diameter of 10 mm, and a height of 7 mm. The component utilizes the 3N2 soft ferrite material, which provides an initial permeability (µi) of 850. Key magnetic parameters include an effective length (le) of 49.6 mm, an effective cross-sectional area (Ae) of 14.2 mm², and an effective volume (Ve) of 703 mm³. The core features a magnetic factor (ΣI/A) of 3.49 mm⁻¹ and is supplied without a gap.

Ferrite Cable Procurement Notes

Verify the exact material designation 3N2 against current manufacturer datasheets, as material grades may be updated or superseded. Confirm RoHS compliance status and packaging quantities directly with authorized distributors. Ensure the epoxy coating specification meets your assembly process requirements regarding temperature resistance and adhesion.

Ferrite Cable Selection Notes

Select this core based on the required initial permeability of 850 and the specific dimensional constraints of 20x10x7 mm. Evaluate the 3N2 material properties against your operating frequency and flux density requirements. Compare the effective volume and magnetic factor with alternative cores to ensure adequate performance for your inductance and saturation needs.

Ferrite Cable Part Context

This component is part of Ferroxcube's TX series of epoxy-coated toroidal cores. The series offers a wide range of sizes and materials designed for various transformer and inductor applications. The TX20/10/7 variant specifically addresses space-constrained designs requiring moderate permeability and reliable magnetic performance in compact form factors.

Ferrite Cable Replacement Considerations

Check for direct substitutes within the TX series with identical dimensions but different materials if frequency response adjustments are needed. Verify compatibility with existing bobbin or winding tooling when considering alternative manufacturers' toroidal cores.
