KH090-125A High Flux Toroid Core 22.90×14.07×7.62 125µ

KH090-125A is a high-performance toroidal magnetic core manufactured by KDM, a reputable name in passive components. This specific model, part of the High Flux series, is engineered to provide superior magnetic properties for a wide range of power electronics applications. Toroid cores are fundamental components in inductors, transformers, and chokes, where they are crucial for efficiently storing magnetic energy and facilitating energy transfer. The toroidal shape inherently offers excellent magnetic flux containment, minimizing electromagnetic interference (EMI) and maximizing efficiency, making the KH090-125A an ideal choice for demanding circuit designs requiring stable inductance and high power handling capabilities.

Key Specifications

This KDM High Flux Toroid Core boasts a set of precise specifications that define its performance characteristics:

• Series: High Flux – This designation indicates that the core material is specifically formulated for high magnetic flux density applications, allowing for smaller inductor designs that can handle significant power without saturating.
• Weight (g): 1.410 – A relatively lightweight component, which is beneficial for applications where overall system weight is a concern, such as portable devices or aerospace electronics.
• Core Material: High Flux – The core material is a specialized powdered iron alloy designed to offer a unique combination of high saturation flux density and low core losses, particularly at higher frequencies, making it suitable for power factor correction (PFC) chokes and output inductors.
• Mounting Type: Through Hole – This indicates that the core is designed to be mounted using leads that pass through holes in a printed circuit board (PCB), providing robust mechanical stability and reliable electrical connections.
• Component Type: Magnetic Core (Toroid) – Confirms its primary function as a magnetic core and its specific toroidal geometry, which is known for its self-shielding properties and efficient magnetic coupling.
• AL Value (nH/N²): 90 – The inductance factor, or AL value, represents the inductance (in nanohenries) per turn squared. An AL value of 90 nH/N² allows designers to accurately calculate the required number of turns to achieve a specific inductance value for their coil.
• 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 indicates a good balance between high inductance and resistance to saturation, making it versatile for various inductor and transformer designs.
• Effective Area Ae (cm²): 0.331 – The effective cross-sectional area of the core, which is critical for calculating the magnetic flux density and determining the core’s ability to handle specific power levels without saturating.
• Effective Length le (cm): 5.670 – The effective magnetic path length, used in conjunction with the effective area to characterize the core’s magnetic circuit and calculate parameters like reluctance.
• Dimensions OD×ID×HT (mm): 22.90×14.07×7.62 – These are the precise outer diameter (OD), inner diameter (ID), and height (HT) of the core before any coating. These dimensions are crucial for mechanical integration into circuit boards and enclosures.
• Effective Volume Ve (cm³): 1.880 – The effective volume of the core material, which is directly related to the core’s energy storage capability and its power handling capacity.
• Dimensions After Coating (mm): 23.62×13.39×8.38 – These dimensions include the protective coating, which provides electrical insulation and mechanical protection, and are important for final assembly and clearance considerations.

Features and Benefits

• High Saturation Flux Density: The High Flux material allows for higher magnetic flux density, enabling the design of smaller, more compact inductors and transformers that can handle significant power without saturating, leading to space and weight savings.
• Low Core Losses: Engineered to minimize energy losses due to hysteresis and eddy currents, especially at higher operating frequencies, which translates to improved efficiency and reduced heat generation in power conversion circuits.
• Excellent Magnetic Shielding: The toroidal geometry inherently provides a closed magnetic path, which significantly reduces stray magnetic fields and minimizes electromagnetic interference (EMI) with adjacent components, simplifying PCB layout and compliance.
• Stable Inductance Over Temperature: The specialized core material ensures that the inductance value remains relatively stable across a wide range of operating temperatures, providing reliable performance in varying environmental conditions.
• Robust Mechanical Design: Designed for through-hole mounting, the core offers a secure and stable physical integration into printed circuit boards, ensuring long-term reliability in demanding applications.
