V18073T Mn Zn Ferrite Magnetic Ring EMI Noise Suppression Core For Home Appliance Power Cord Anti Interference Filter

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: How do I choose a suitable ferrite magnetic ring for my project? A: You need to confirm key factors such as working frequency range, cable outer diameter for inner‑diameter matching, target impedance value and operating temperature. Share your cable specification and interference frequency with us, we can recommend the proper model and material grade.

Q2: Will ferrite magnetic ring become saturated under high current? A: Yes. Large DC current may trigger magnetic saturation and reduce filtering effect. If your working condition involves high current, please offer rated current parameter, we will recommend suitable size or material to avoid saturation risk.

Q3: What elements will influence the actual filtering performance of ferrite magnetic rings? A: Major influencing factors contain ferrite material permeability, working frequency, physical dimension of magnetic ring, number of wire turns through core and practical working temperature. Within limits, more wire turns through the hole can achieve higher impedance.

Q4: Can I get samples for performance verification? A: Evaluation samples are available. Customers only need to cover freight cost. Please inform us of exact model and sample quantity you require.

Q5: Can you provide customized magnetic rings with special dimension or material parameters? A: Custom service is acceptable. We can adjust outer diameter, inner diameter, height and ferrite material performance according to your drawings or technical requirements. Minimum order quantity will be required for customized products.
