Ferroxcube Ferrite Toroid Core 3E5 TX42 75g
High-inductance Ferroxcube toroid core (3E5, TX42). Ideal for chokes, transformers, baluns. 134mm² Ae, 12.9µH AL.
The Ferrite Toroid Core (TX42, 3E5 material) from Ferroxcube is a ring-shaped core engineered for high-performance magnetic applications. Its closed magnetic circuit and homogeneous cross-section deliver the highest inductance per turn (AL factor), making it ideal for designs that require maximum efficiency in a compact form.
This toroid is particularly suited for common mode chokes, transformers, baluns, and other components where high inductance is critical. The smooth, soft chamfered edges allow for clean winding without damaging the wire insulation, while the available coatings (epoxy, nylon, parylene C, or lacquer) provide breakdown voltage protection that varies with core size and material.
Energy storage performance can be optimized by gapping the core, adding design flexibility for power applications. With a wide size range from 2.5mm to 152mm, this core supports diverse industrial uses, from signal filtering to power conversion.
