1. Product Overview

The V‑series ring‑shaped soft magnetic core is manufactured from high‑grade 1K107B soft magnetic alloy, tailored for high‑frequency EMI mitigation and common‑mode noise filtration. Boasting an exceptional initial permeability of 80000, alongside maximum permeability hitting 300000 and saturation magnetic flux density at 1250 mT, this component exhibits superior noise‑absorbing capacity and steady magnetic permeability at high‑frequency operation. Its Curie temperature stands at 570℃, with an extensive operating temperature span of ‑50℃ to 150℃, enabling steady magnetic performance amid frigid conditions, intense heat and drastic temperature swings. Thanks to high electrical resistivity and minimal eddy‑current loss, paired with precise dimensional accuracy and dependable lot‑to‑lot uniformity, this magnetic core can curb high‑frequency common‑mode disturbance within electronic circuitry, enhance signal integrity and cut down equipment noise. It assists end‑devices in satisfying EMC compliance standards.

2. Application Scope & Purpose

This toroidal magnetic ring finds broad deployment in common‑mode inductors, EMC filter assemblies and high‑frequency noise‑reduction circuits. Typical use cases cover switching power supplies, power adapters, industrial power supplies, household electric appliances, telecom power units, vehicle‑mounted electronics and smart control hardware. Its primary function is to dampen high‑frequency common‑mode electromagnetic interference on power and signal cables, filter out spurious noise generated during equipment operation, prevent signal distortion and device faults triggered by electromagnetic disturbance, boost the overall anti‑interference capacity of electronic hardware and improve the EMC certification success rate of finished products.
