Product Details

1mH 60A Large Toroidal Inductor Coil High Current 1 Winding Double Magnetic Ring

1.Product Description

This **1mH 60A Customized Large Toroidal Inductor Coil** is designed for high-current applications, featuring a **double magnetic ring structure** for enhanced efficiency and thermal stability. With a **single-winding (1-turn) design**, it minimizes DC resistance (DCR) while supporting **continuous 60A current** and **1mH inductance**, making it ideal for **power converters, inverters, EV charging systems, and industrial motor drives**. The **toroidal shape reduces EMI**, and its **high-temperature-resistant construction** ensures reliable performance in demanding environments. Customizable core materials (e.g., ferrite or powdered iron) allow optimization for low-loss or high-saturation applications.


1. * * High current and high load * * - Supports * * 60A continuous current * *, suitable for high-power conversion, inverters, and industrial drive systems.


2. * * Double magnetic ring structure * * - optimizes magnetic circuit distribution, reduces eddy current losses, improves efficiency and temperature rise performance.


3. * * 1mH high inductance stable output * * - maintains inductance consistency over a wide frequency range and suppresses current ripple.


4. * * Single winding low resistance design * * - reduces direct current resistance (DCR), lowers heat generation, and improves energy efficiency.


5. Ring shaped magnetic core with low EMI - The enclosed magnetic circuit structure effectively suppresses electromagnetic interference and is suitable for high-density power supply systems.


Suitable for harsh scenarios such as new energy, electric vehicles, industrial power supplies, etc., supporting customized magnetic core materials (such as iron silicon aluminum, nanocrystals, etc.).
