KH068-090A-HP is a high-performance toroidal magnetic core manufactured by KDM, a reputable name in passive components. This specific component, part of the KH-HP series, is designed to provide excellent magnetic properties for a wide array of electronic applications, particularly in inductors, transformers, and chokes. Toroid cores are fundamental in power electronics and signal processing due to their ability to confine magnetic flux efficiently, minimizing electromagnetic interference (EMI) and maximizing energy transfer. The KH068-090A-HP, with its precise dimensions and specified permeability, offers a reliable solution for engineers and designers seeking consistent performance in their magnetic circuit designs.

Key Specifications

The KH068-090A-HP boasts several critical specifications that define its performance and suitability for various applications:

• Series: KH-HP: This indicates the core belongs to KDM’s high-performance series, optimized for specific magnetic characteristics and often implying enhanced efficiency or frequency response.
• Weight (g): 0.638: The relatively light weight of the core is important for applications where overall device weight is a concern, such as portable electronics or aerospace components.
• Core Material: KH-HP: This specifies the proprietary magnetic material used by KDM, which is engineered to provide the stated permeability and AL value, crucial for stable inductance over varying conditions.
• Mounting Type: Through Hole: This indicates that the core is designed to be mounted using leads that pass through holes on a printed circuit board (PCB), a common and robust mounting method for magnetic components.
• Component Type: Magnetic Core (Toroid): Clearly identifies the product as a toroidal magnetic core, emphasizing its closed-loop shape which is highly efficient at containing magnetic flux.
• AL Value (nH/N²): 64: The AL value, or inductance factor, represents the inductance (in nanohenries) produced by a single turn squared. A value of 64 nH/N² allows engineers to precisely calculate the number of turns required to achieve a desired inductance.
• Permeability (µ): 90: Permeability is a measure of how easily a material can support the formation of a magnetic field within itself. A permeability of 90 indicates that this core material is well-suited for applications requiring moderate inductance in a compact form factor.
• Effective Area Ae (cm²): 0.232: The effective cross-sectional area is used in inductance calculations and determines the core’s ability to handle magnetic flux without saturation. A larger Ae generally allows for higher power handling.
• Effective Length le (cm): 4.140: The effective magnetic path length is another critical parameter for inductance calculations and understanding the magnetic circuit’s reluctance.
• Dimensions OD×ID×HT (mm): 17.30×9.65×6.35: 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 fit and winding considerations.
• Effective Volume Ve (cm³): 0.960: The effective volume is used in energy storage calculations and helps determine the core’s power handling capability and saturation characteristics.
• Dimensions After Coating (mm): 18.03×9.02×7.11: These dimensions account for the insulating coating applied to the core, which is vital for preventing short circuits between windings and ensuring electrical isolation.

Features and Benefits

• Optimized Magnetic Performance: The KH-HP material and 90µ permeability ensure efficient magnetic flux confinement, leading to lower losses and improved circuit efficiency.
• Compact Toroidal Design: The toroid shape inherently minimizes leakage flux and external electromagnetic interference (EMI), making it ideal for sensitive applications and dense PCB layouts.
• Precise Inductance Control: With an AL value of 64 nH/N², engineers can accurately design inductors and transformers to meet specific inductance requirements with fewer turns.
• Robust Through-Hole Mounting: The through-hole design provides a secure and reliable mechanical connection to the PCB, enhancing durability and vibration resistance.
