Key Specifications
This KDM KH068-125A-H toroid core boasts a set of precise attributes that define its performance and suitability for specific applications:Series: High Flux Plus – This indicates the core material series, known for its high saturation flux density and excellent DC bias performance, making it suitable for high-current applications where inductance stability under load is critical.
Weight (g): 0.638 – The light weight of the core contributes to the overall reduction in the weight of the final electronic assembly, which is beneficial for portable devices and applications where weight is a design constraint.
Core Material: High Flux Plus – Reinforces the use of a specialized powdered iron alloy that offers a unique combination of high saturation flux density and low core losses, especially at higher frequencies, enabling efficient energy storage.
Mounting Type: Through Hole – While the core itself is typically wound with wire, the ‘Through Hole’ designation often refers to how the finished inductor or transformer assembly would be mounted on a PCB, implying a robust and secure physical connection.
Component Type: Magnetic Core (Toroid) – Clearly identifies the product as a fundamental magnetic component, specifically a toroid, which is a ring-shaped core known for its self-shielding properties and efficient magnetic coupling.
AL Value (nH/N²): 89 – The inductance factor (AL value) indicates the inductance per turn squared. An AL value of 89 nH/N² allows engineers to precisely calculate the number of turns required to achieve a desired inductance for a given application, streamlining design.
Permeability (µ): 125 – Permeability is a measure of how easily a material can support the formation of a magnetic field within itself. A permeability of 125 signifies a good balance between high inductance and resistance to saturation, making it versatile for various power applications.
Effective Area Ae (cm²): 0.232 – The effective cross-sectional area is crucial for calculating the magnetic flux density and ensuring the core does not saturate under expected operating currents. A larger Ae generally allows for higher power handling.
Effective Length le (cm): 4.140 – The effective magnetic path length is used in conjunction with Ae to determine the core’s magnetic properties and is vital for accurate inductance calculations and understanding the magnetic circuit.
Dimensions OD×ID×HT (mm): 17.30×9.65×6.35 – These are the outer diameter, inner diameter, and height of the uncoated core, providing essential physical parameters for mechanical design, winding calculations, and space allocation within an electronic enclosure.
Effective Volume Ve (cm³): 0.960 – The effective volume is important for calculating core losses and thermal management. A smaller volume can lead to a more compact design, while its thermal properties need careful consideration.
Dimensions After Coating (mm): 18.03×9.02×7.11 – These dimensions account for the protective coating applied to the core, which provides electrical insulation and mechanical robustness. These are the final dimensions to consider for assembly and winding.
Features and Benefits
