Custom V18073T Ferrite Magnetic Ring High Resistivity Soft MnZn Ferrite Core For Cable Assembly EMC Compliance Application

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: Do ferrite magnetic rings need to pass any certification such as RoHS and REACH? A: Our standard ferrite magnetic rings comply with RoHS and REACH requirements. Relevant test reports can be provided upon customer request.

Q2: What is your normal lead‑time for standard ferrite magnetic ring orders? A: For standard in‑stock models, lead time is 3‑7 working days. For mass production orders without stock, production cycle is 15‑25 working days.

Q3: How should I install toroidal ferrite magnetic ring on cables? A: Pass the whole cable through the inner hole of toroidal core. Keep the magnetic ring close to noise source or equipment connector for optimal filtering result. Avoid placing it near heat source.

Q4: What is the storage requirement for ferrite magnetic rings? A: Store in dry and room‑temperature environment. Avoid heavy impact and dropping, ferrite material is brittle and easy to crack under mechanical shock.

Q5: What packaging do you use for ferrite magnetic rings? A: Standard packing is anti‑static plastic bag plus carton box. Special packing requirement can be arranged according to customer’s demand.
