Key Specifications

The KPH135-060A-HP toroid core boasts several critical specifications that define its performance and suitability for various applications: * Series: KPH-HP – This designates the specific material composition and manufacturing process employed by KDM, indicating a high-performance grade core optimized for efficiency and stability. * Weight (g): 4.010 – The relatively light weight of 4.010 grams is important for applications where overall device weight is a concern, such as portable electronics or aerospace components, without compromising magnetic properties. * Core Material: KPH-HP – The core material itself, KPH-HP, is a specialized blend designed to offer a specific permeability and low core losses, crucial for maintaining efficiency in power conversion and signal filtering applications. * Mounting Type: Through Hole – While the core itself doesn’t have mounting holes, this attribute typically refers to how components built around this core (like inductors or transformers) would be mounted on a PCB, suggesting compatibility with standard through-hole assembly processes. * Component Type: Magnetic Core (Toroid) – This clearly identifies the product as a toroid-shaped magnetic core, emphasizing its closed magnetic path which minimizes flux leakage and enhances performance. * AL Value (nH/N²): 8 – The AL value, or inductance factor, of 8 nH/N² indicates the inductance produced per turn squared. A higher AL value means fewer turns are needed to achieve a desired inductance, which can save space and reduce copper losses. * Permeability (µ): 60 – A permeability of 60 signifies the material’s ability to support the formation of a magnetic field within itself. This value is critical for determining the inductance of a coil wound around the core and is chosen for specific frequency ranges and power levels. * Effective Area Ae (cm²): 0.454 – The effective cross-sectional area of 0.454 cm² is used in magnetic circuit calculations to determine flux density and core saturation limits, ensuring the core can handle the required magnetic flux without saturating. * Effective Length le (cm): 8.950 – The effective magnetic path length of 8.950 cm is another crucial parameter for magnetic circuit design, influencing the reluctance of the magnetic path and thus the overall inductance. * Dimensions OD×ID×HT (mm): 34.30×23.40×8.89 – These precise dimensions (Outer Diameter × Inner Diameter × Height) are vital for mechanical fit and winding calculations, ensuring the core fits into designated spaces and allows for sufficient winding turns. * Effective Volume Ve (cm³): 4.060 – The effective volume of 4.060 cm³ is used in calculating core losses and energy storage capabilities, providing insight into the core’s thermal performance and power handling. * Dimensions After Coating (mm): 35.10×22.56×9.83 – These dimensions account for any insulating coating applied to the core, which is essential for preventing short circuits between windings and the core, and for ensuring proper insulation in the final assembly.
