KPH131-040A is a high-performance Sendust Plus Toroid Core manufactured by KDM, a reputable name in passive components. This magnetic core is specifically designed to enhance the efficiency and performance of various inductive components by providing a controlled path for magnetic flux. As a toroid, its ring shape inherently offers excellent magnetic shielding and minimizes external electromagnetic interference, making it ideal for applications requiring high stability and low loss. The Sendust Plus material, a specialized alloy of iron, silicon, and aluminum, is renowned for its superior magnetic properties, including high saturation flux density, low core loss, and excellent temperature stability, making this core a robust solution for demanding power electronics and EMI filtering applications.

Key Specifications

The KPH131-040A core boasts several critical specifications that define its operational characteristics and suitability for various designs. Its Series, “Sendust Plus,” indicates the advanced material composition, ensuring high performance and reliability. The Weight of 2.927 grams is crucial for applications where component mass is a factor, such as in portable devices or aerospace. The Core Material, Sendust Plus, is a key differentiator, offering a balance of high saturation flux density and low core loss, superior to traditional ferrite cores in many high-frequency, high-current scenarios. The Mounting Type is “Through Hole,” signifying that the core is typically integrated into circuits by winding wire directly through its center, a common and robust method for toroids. The Component Type, “Magnetic Core (Toroid),” precisely identifies its function and form factor. The AL Value (nH/N²) of 34 is a fundamental parameter, representing the inductance factor per turn squared. This value is essential for engineers to calculate the required number of turns to achieve a specific inductance. A Permeability (µ) of 40 indicates the material’s ability to support the formation of a magnetic field within itself, directly influencing the inductance achieved. The Effective Area Ae (cm²) of 0.551, Effective Length le (cm) of 8.147, and Effective Volume Ve (cm³) of 4.490 are geometric parameters that are vital for calculating core losses, saturation characteristics, and thermal performance. These dimensions, along with the Dimensions OD×ID×HT (mm) of 33.00×19.90×8.76, provide the physical footprint and internal diameter for winding, while the Dimensions After Coating (mm) of 33.83×19.30×9.70 account for the protective coating that enhances insulation and durability.
