Selection of Nanocrystalline Common-Mode Inductors

Nanocrystalline common-mode inductors for OBC, 800V EV drivetrains and industrial power supplies require careful material grade selection beyond initial permeability, proper winding techniques to acco

A Complete Guide to Current Sensor Core Selection: Magnetic Material Holds th...

Struggling with sensor accuracy drift or waveform distortion? The root cause often lies not in the circuit, but in the magnetic core material. This guide breaks down six主流 core materials—from ferrite

Resistivity (ρ) – The Eddy Current Killer and Selection Bible for Magnetic Cores

Resistivity (ρ) is the "eddy current killer" for magnetic cores, directly determining high-frequency loss and temperature rise. This article compares ρ across silicon steel, nanocrystalline, ferrites,

In-depth Analysis of Magnetic Field Heat Treatment Process for Common-mode Co...

I. First, Understand: Why Magnetic Field Heat Treatment Is Mandatory for Common-mode Cores With the widespread adoption of new energy photovoltaic systems, energy storage inverters, vehicle-to-grid (V

Forms of Amorphous & Nanocrystalline Soft Magnetic Materials

Amorphous and nanocrystalline soft magnetic materials exist in three key forms. Ribbons (the most mature) are ideal for transformer cores. Powders (fast-growing) suit powder cores and EMI filters. Bul

What is soft magnetic material ?

Soft magnetic materials refer to a category of magnetic materials with coercive force lower than 1000 A/m, featuring low coercivity and high magnetic permeability. Their core characteristics include e

Curie Temperature (Tc) – Core Parameter of Soft Magnetic Materials

Curie Temperature Table of Soft Magnetic Materials In the design of electronic devices such as transformers, sensors and instrument transformers, we often encounter a common problem: the performance o

What is Initial Permeability

1. Definition Initial permeability (symbol: μᵢ; relative initial permeability μᵣᵢ in engineering use) refers to the magnetic conductivity of magnetic materials when they start to be magnetized f

Application of Common Mode Choke Core Materials: Nanocrystalline vs Ferrite

What is a Common Mode Choke? 1. Professional Definition A common mode choke, also known as a common mode inductor, is a passive magnetic component that suppresses electromagnetic interference (EMI) bi
