KAM200-060A Nanodust Toroid Core 50.80×31.80×13.50 60µ

Overview

KAM200-060A is a high-performance Nanodust Toroid Core manufactured by KDM, a reputable name in passive components. This magnetic core is a critical element in various electronic circuits, primarily functioning to store magnetic energy and facilitate efficient power conversion and filtering. Its toroidal shape ensures a closed magnetic path, which minimizes flux leakage and external electromagnetic interference, making it highly effective for applications requiring stable inductance and low losses. The Nanodust material, a proprietary blend, offers superior performance characteristics compared to traditional ferrite or iron powder cores, particularly in high-frequency and high-current environments.

Key Specifications

• Series: Nanodust
  The Nanodust series signifies KDM’s advanced material technology, offering a unique composition that provides a balance of high saturation flux density, low core losses, and excellent temperature stability. This material is particularly well-suited for power inductors and chokes operating at higher frequencies and temperatures where conventional materials might saturate or become inefficient.
• Weight (g): 7.500
  The relatively light weight of 7.500 grams indicates a compact and manageable component, which is beneficial for designs where space and overall product weight are critical considerations. Despite its low weight, it delivers robust magnetic performance.
• Core Material: Nanodust
  As mentioned, Nanodust is a specialized composite magnetic material. It excels in applications requiring high energy storage capability and reduced core losses, especially under high DC bias conditions. This makes it ideal for power factor correction (PFC) chokes, output inductors, and other energy storage applications.
• Mounting Type: Through Hole
  The ‘Through Hole’ mounting type implies that this toroid core is designed to be integrated into a circuit board by passing leads through holes and soldering them. This method provides a mechanically robust connection, suitable for components that may experience vibration or require strong physical stability.
• Component Type: Magnetic Core (Toroid)
  This specifies the fundamental nature of the component. A magnetic core is the central part of an inductor or transformer, concentrating magnetic flux. The toroidal shape is highly efficient due to its self-shielding properties and uniform magnetic field distribution.
• AL Value (nH/N²): 73
  The AL value, or inductance factor, of 73 nH/N² represents the inductance produced per turn squared. This parameter is crucial for designers to calculate the required number of turns to achieve a specific inductance value for their application, ensuring precise control over the circuit’s magnetic properties.
• Permeability (µ): 60
  A permeability of 60 indicates the material’s ability to support the formation of a magnetic field within itself. This value is optimized for applications requiring a balance between high inductance and resistance to saturation under DC bias, making it suitable for a wide range of power conversion tasks.
• Effective Area Ae (cm²): 1.251
  The effective area is a calculated parameter representing the cross-sectional area of the core through which magnetic flux passes. An Ae of 1.251 cm² is used in inductance and saturation calculations, providing insight into the core’s energy handling capability.
• Effective Length le (cm): 12.730
  The effective length is the average length of the magnetic path within the core. At 12.730 cm, this value, along with Ae, is essential for accurate magnetic circuit design, particularly when determining the magnetizing force and flux density.
• Dimensions OD×ID×HT (mm): 50.80×31.80×13.50
  These dimensions specify the core’s physical size: Outer Diameter (OD) of 50.80 mm, Inner Diameter (ID) of 31.80 mm, and Height (HT) of 13.50 mm. These measurements are critical for mechanical fitment and ensuring the core fits within the allocated space in a design.
• Effective Volume Ve (cm³): 15.930
  The effective volume of 15.930 cm³ is another parameter used in core loss calculations and energy storage capacity assessments. A larger effective volume generally correlates with higher energy handling capability.
• Dimensions After Coating (mm): 51.69×30.94×14.35
  These dimensions (51.69 mm OD, 30.94 mm ID, 14.35 mm HT) account for the protective coating applied to the core. The coating provides electrical insulation, mechanical protection, and can slightly alter the overall dimensions, which is important for precise assembly and preventing short circuits.

Features and Benefits

• High Saturation Flux Density: The Nanodust material allows for a higher saturation flux density compared to traditional materials, enabling the core to handle higher currents without saturating, which is crucial for power applications.
