Key Specifications

The Series, “High Flux Plus,” denotes the specific material composition and performance characteristics of this core, indicating its suitability for demanding applications requiring high energy storage and efficiency. The Weight (g) of 1.410 grams is crucial for designers concerned with the overall mass of their electronic assemblies, particularly in portable or aerospace applications where weight reduction is paramount. The Core Material, also “High Flux Plus,” is a specialized powdered iron alloy known for its high saturation flux density and relatively low core losses across a wide range of frequencies, making it superior to traditional ferrite cores in certain high-current applications. The Mounting Type, “Through Hole,” signifies that this component is designed for conventional PCB assembly, where leads or wires are passed through holes in the circuit board and soldered. The Component Type, “Magnetic Core (Toroid),” precisely identifies its form factor and primary function as a magnetic element for inductors or transformers. The AL Value (nH/N²) of 90 represents the inductance factor, indicating the inductance generated per turn squared. This value is fundamental for calculating the required number of turns to achieve a specific inductance. The Permeability (µ) of 125 is a measure of how easily a material can support the formation of a magnetic field within itself, directly influencing the inductance and magnetic properties of the core. The Effective Area Ae (cm²) of 0.331 square centimeters is the cross-sectional area through which the magnetic flux passes, essential for calculating flux density and core losses. The Effective Length le (cm) of 5.670 centimeters is the average length of the magnetic path within the core, used in conjunction with Ae to determine the core’s magnetic properties. The Dimensions OD×ID×HT (mm) of 22.90×14.07×7.62 millimeters specify the outer diameter, inner diameter, and height of the core, critical for mechanical design and PCB layout. The Effective Volume Ve (cm³) of 1.880 cubic centimeters is the total volume of the magnetic material, relevant for thermal management and overall core size. Finally, the Dimensions After Coating (mm) of 23.62×13.39×8.38 millimeters provide the final dimensions including any protective coating, which is important for precise fitment in enclosures or alongside other components.
