KH300-026A High Flux Toroid Core 77.80×49.20×12.70 26µ

KH300-026A is a high-performance toroidal magnetic core manufactured by KDM, a reputable name in passive components. This specific component falls under the Magnetics – Components category, specifically designed as a High Flux Core. Its primary function is to provide an efficient path for magnetic flux, crucial for applications requiring high energy storage and low core losses. Toroidal cores are favored for their self-shielding properties and efficient use of magnetic material, making them ideal for inductors, transformers, and chokes in power electronics.

Key Specifications

The KH300-026A boasts several critical specifications that define its performance and suitability for various applications. The Series, ‘High Flux’, indicates its specialized material composition designed to handle high magnetic flux densities before saturation, making it suitable for high-power applications. With a Weight of 17.990 grams, this core offers a balance of robust construction and manageable mass for integration into electronic assemblies. The Core Material, also ‘High Flux’, reiterates its advanced magnetic properties, ensuring efficient energy transfer and reduced losses compared to standard ferrite or iron powder cores. Its Mounting Type is ‘Through Hole’, implying it is typically mounted using a central winding or a bobbin, allowing for secure integration into circuit boards or enclosures. As a Component Type, it is a ‘Magnetic Core (Toroid)’, highlighting its ring-shaped geometry which inherently minimizes flux leakage and external electromagnetic interference. The AL Value (nH/N²) of 30 is a crucial parameter, representing the inductance factor per turn squared, directly influencing the inductance achieved with a given number of windings. A higher AL value means fewer turns are needed for a specific inductance. The Permeability (µ) of 26 indicates the material’s ability to support the formation of a magnetic field within itself, with this specific value being optimized for high-frequency and high-current applications. The Effective Area Ae (cm²) of 1.770 and Effective Length le (cm) of 20.000 are geometric parameters used in magnetic circuit calculations, essential for determining inductance and flux density. The Dimensions OD×ID×HT (mm) of 77.80×49.20×12.70 specify the outer diameter, inner diameter, and height of the core, respectively, which are critical for mechanical design and winding considerations. The Effective Volume Ve (cm³) of 34.700 is another key parameter for energy storage calculations. Finally, the Dimensions After Coating (mm) of 78.90×48.20×13.84 provide the slightly larger dimensions once the protective coating is applied, which is important for final assembly and clearance planning.

Features and Benefits

• High Flux Density Capability: The High Flux material allows for higher magnetic flux density before saturation, enabling smaller core sizes for a given power level and reducing overall component footprint.
• Low Core Losses: Optimized material composition minimizes energy dissipation as heat, leading to higher efficiency in power conversion applications and cooler operation.
• Excellent Inductance Stability: Provides stable inductance over a wide range of operating temperatures and DC bias currents, ensuring reliable performance in demanding environments.
• Self-Shielding Toroidal Geometry: The toroidal shape inherently confines the magnetic field within the core, reducing electromagnetic interference (EMI) to surrounding components and simplifying circuit design.
• Robust Mechanical Design: Precision manufacturing ensures consistent dimensions and structural integrity, facilitating easy winding and secure mounting.

Typical Applications

The KDM KH300-026A High Flux Toroid Core is highly versatile and finds application in numerous critical electronic systems. One primary application is in DC-DC Converters, particularly in switch-mode power supplies (SMPS) where it is used to create highly efficient inductors and transformers for voltage regulation and energy storage. Its high flux capability allows for compact designs in these power-dense applications. Another significant use case is in Power Factor Correction (PFC) Chokes. In PFC circuits, these cores help improve the power factor of AC-DC power supplies, reducing harmonic distortion and increasing overall system efficiency, which is crucial for compliance with power quality standards. They are also extensively employed in Output Inductors for Inverters, such as those found in solar power systems or uninterruptible power supplies (UPS). Here, the core helps smooth the output current and filter harmonics, ensuring a clean and stable AC waveform. Furthermore, the KH300-026A is suitable for EMI/RFI Filters, where it forms the core of common-mode or differential-mode chokes, effectively suppressing unwanted electromagnetic noise and ensuring signal integrity in sensitive electronic equipment. Finally, its robust performance makes it ideal for High-Current Inductors in industrial power supplies, motor drives, and welding equipment, where reliable energy storage and current handling are paramount.
