V18073T Toroid Ferrite Magnetic Core Anti EMI Ferrite Ring For Power Adapter Charger Cable Electromagnetic Suppression

Product Brief

V18073T toroidal ferrite magnetic ring is produced from high‑performance VN02 Mn‑Zn soft ferrite material. It has initial permeability of 650±20%, saturation magnetic flux density up to 330 MT and Curie temperature above 110℃. Benefiting from high electrical resistivity over 10⁵ Ω·m and low relative loss factor at 0.1 MHz, it maintains stable magnetic performance under varying temperature conditions. This component delivers excellent high‑frequency EMI suppression to filter electromagnetic noise on cables and wire harnesses. Optimized for easy threading and mass assembly, it features reliable batch‑to‑batch consistency. Sample testing, bulk supply and customized parameters are available for diverse EMC filtering projects.

Product Description

V18073T ferrite magnetic ring is specially engineered for cable EMI noise elimination. Adopting VN02 manganese‑zinc ferrite, it keeps low loss at high‑frequency working status with limited heat generation during long‑time continuous operation. Its magnetic property will not deteriorate obviously under temperature fluctuation. The toroidal core absorbs high‑frequency interference effectively to improve conducted and radiated interference performance, assisting end products to meet EMC standards including EN55014 and GB9254.

With regular dimensional tolerance, the magnetic ring enables convenient cable threading for automated assembly lines. Strict quality inspection is carried out in every production procedure to secure stable magnetic characteristics of each batch. It can be directly matched with power cords and multi‑core wire harnesses. We serve customers from home appliance, power adapter and industrial control industries, supporting both sample evaluation and large‑volume orders.

Application Scope & Usage

Application Scope

‑ Household appliances: massage devices, beauty equipment, small kitchen appliances and consumer electronics ‑ Power supplies: switching power supply, power adapter and battery charger ‑ Cable and wire harness: power cords, signal cables and multi‑core assembled wires ‑ Industrial equipment: measuring instruments, automation devices and control wiring

Usage

It is mainly applied for EMI noise suppression of various cables. Installed on power lines or signal cables, the magnetic ring suppresses high‑frequency conducted interference and electromagnetic radiation. It strengthens the anti‑interference capacity of whole systems and prevents abnormal equipment operation caused by electromagnetic disturbance, helping finished goods pass domestic and international EMC certification tests.

General FAQ for Ferrite Magnetic Rings

Q1: Can I get free test samples of ferrite magnetic rings? A: We can offer free evaluation samples. Buyers need to cover the courier freight cost. Please tell us model number and sample quantity you need.

Q2: Can you customize special size ferrite magnetic rings according to my drawing? A: Custom service is supported. We can adjust outer diameter, inner diameter, height and shape. Custom order requires certain MOQ based on tooling condition.
