Key Specifications
This Sendust Toroid Core boasts several key specifications that define its operational characteristics and suitability for specific applications. The ‘Series’ designation as ‘Sendust’ immediately identifies the core material, known for its excellent saturation characteristics and low core losses, especially at higher frequencies. The ‘Weight (g)’ of 1.561 grams indicates a lightweight component, beneficial for overall device weight reduction. The ‘Core Material’ being ‘Sendust’ is crucial, as Sendust (an alloy of iron, silicon, and aluminum) offers a superior balance of high saturation flux density, low core loss, and good temperature stability compared to other core materials like ferrite or powdered iron. Its ‘Mounting Type’ is ‘Through Hole’, meaning it is designed to be mounted directly onto a PCB using leads that pass through holes, ensuring a secure physical and electrical connection. The ‘Component Type’ is specified as ‘Magnetic Core (Toroid)’, highlighting its fundamental role in forming inductors, transformers, and chokes. The ‘AL Value (nH/N²)’ of 39 represents the inductance factor, indicating the inductance generated per turn squared, which is vital for designers calculating the number of turns needed for a desired inductance. A ‘Permeability (µ)’ of 40 signifies the material’s ability to support the formation of a magnetic field, with 40µ being a common value for general-purpose power applications. The ‘Effective Area Ae (cm²)’ of 0.497 cm² and ‘Effective Length le (cm)’ of 6.352 cm are geometric parameters used in magnetic circuit calculations to determine inductance and magnetic flux density. The ‘Dimensions OD×ID×HT (mm)’ of 26.90×14.70×8.64 mm specify the outer diameter, inner diameter, and height, respectively, which are critical for mechanical fit and winding space. The ‘Effective Volume Ve (cm³)’ of 3.155 cm³ is another geometric parameter useful for calculating energy storage capacity. Finally, the ‘Dimensions After Coating (mm)’ of 27.70×14.10×9.45 mm provide the final dimensions including any protective coating, which is important for space allocation in the final assembly.
