KAM080-060A Nanodust Toroid Core 20.30×12.70×6.35 60µ

KAM080-060A is a high-performance Nanodust Toroid Core manufactured by KDM, a reputable name in passive components. This magnetic core is a crucial element in various electronic circuits, designed to efficiently store and transfer magnetic energy. Its toroidal shape, characterized by a donut-like form, provides a closed magnetic path, which significantly reduces electromagnetic interference (EMI) and leakage flux, leading to improved circuit efficiency and reduced losses. The core’s primary function is to concentrate magnetic flux, enhancing the inductance of windings placed around it, making it indispensable in applications requiring stable and efficient magnetic properties, such as inductors, transformers, and chokes.

Key Specifications

This Nanodust Toroid Core boasts several critical specifications that define its performance and suitability for specific applications:

Series: Nanodust – This indicates the specific product line, highlighting the advanced Nanodust material technology used, known for its superior magnetic properties and high saturation flux density, making it ideal for high-frequency and high-power applications.

Weight (g): 1.140 – The relatively low weight of 1.140 grams makes this component suitable for weight-sensitive applications while still providing robust magnetic performance.

Core Material: Nanodust – The use of Nanodust material is a key differentiator. Nanodust cores are composite materials consisting of fine magnetic particles dispersed in a non-magnetic binder, offering a unique combination of high permeability, low core losses at high frequencies, and excellent DC bias characteristics, which are critical for power conversion and filtering applications.

Mounting Type: Through Hole – This specifies that the core is designed for through-hole mounting, a common and reliable method for securing components to a printed circuit board (PCB), ensuring mechanical stability and robust electrical connections.

Component Type: Magnetic Core (Toroid) – Clearly identifies the component as a toroidal magnetic core, emphasizing its specific geometry and primary function in magnetic circuits.

AL Value (nH/N²): 32 – The AL value, or inductance factor, represents the inductance in nanohenries per square of turns. An AL value of 32 nH/N² is a critical parameter for designers, allowing them to precisely calculate the required number of turns to achieve a desired inductance for their specific inductor or transformer design.

Permeability (µ): 60 – Permeability is a measure of how easily a material can be magnetized. A permeability of 60 indicates that the Nanodust material can effectively concentrate magnetic flux, contributing to higher inductance values and efficient energy storage within the core.

Effective Area Ae (cm²): 0.226 – The effective cross-sectional area of the core is crucial for determining the magnetic flux density and energy storage capability. An Ae of 0.226 cm² is used in calculations for voltage and current handling capacities.

Effective Length le (cm): 5.090 – The effective magnetic path length is another vital parameter for magnetic circuit design, influencing the reluctance and overall magnetic performance of the core.

Dimensions OD×ID×HT (mm): 20.30×12.70×6.35 – These are the precise outer diameter (OD), inner diameter (ID), and height (HT) of the core in millimeters. These dimensions are essential for mechanical fit, PCB layout, and winding calculations, ensuring the core fits within the designated space and can accommodate the required wire gauge for windings.

Effective Volume Ve (cm³): 1.150 – The effective volume of the core is directly related to its energy storage capacity and is a key factor in thermal management and power handling capabilities.

Dimensions After Coating (mm): 21.10×12.07×7.11 – These dimensions provide the final size of the core after any protective coating has been applied, which is important for final assembly and clearance considerations.

Features and Benefits
