Product Introduction

The V18001A is a premium split snap-on NiZn ferrite magnetic ring independently developed by VIIP, adopting high-performance VN09 ferrite raw material. Equipped with a UL94-V2 flame-retardant outer casing, this magnetic ring features outstanding high-frequency impedance characteristics, reaching no less than 85Ω impedance at 25MHz and 175Ω at 100MHz, which can effectively attenuate high-frequency EMI and RFI electromagnetic noise on various cables. Benefiting from the innovative clip-on split structure, the product supports fast installation on finished wiring harnesses and cables without wire cutting or re-wiring, greatly facilitating post-production EMC optimization and rectification. All finished products are subjected to rigorous visual and performance testing to ensure stable and consistent batch quality, helping electronic manufacturers efficiently pass EMC compliance certification.

Application Scope

Home Smart Appliances: Widely applicable to power lines of air purifiers, inverter air conditioners, microwave ovens, smart refrigerators and various smart home electrical equipment that require electromagnetic interference suppression.

Consumer Electronic Devices: Perfect for anti-interference processing of data cables, audio signal lines, lighting connecting wires and internal harnesses of various small civilian electronic products.

Industrial Control Equipment: Suitable for EMC optimization of internal wiring of low-power control modules, miniature industrial electronic equipment and automation accessories that are susceptible to high-frequency electromagnetic interference.

Purpose

Effectively suppress high-frequency conducted electromagnetic interference transmitted along power and signal cables, reduce mutual EMI and RFI interference between adjacent electronic equipment in the same circuit.

Stabilize the operating state of internal circuit systems, prevent abnormal phenomena such as chip misjudgment, program crash and accidental device restart caused by electromagnetic noise.

Optimize the overall electromagnetic compatibility performance of finished products, reduce EMC test failure rates, and greatly shorten the certification rectification cycle and R&D iteration cost for manufacturers.

FAQ

Q2: Is it necessary to wind the cable multiple times through the magnetic ring? A2: Multiple turns will significantly increase low-to-medium frequency impedance and enhance noise suppression capability. If the product has serious EMC interference or insufficient single-ring effect, winding 2–3 turns is recommended; for conventional interference suppression, a single penetration meets standard requirements.

Q3: Are clip-on ferrite cores reusable after disassembly? A3: VIIP split ferrite magnetic rings feature a flexible snap structure. They can be disassembled and reinstalled multiple times without damage to the shell or magnetic core, supporting repeated testing, sample modification and mass production replacement for manufacturers.

Q4: What temperature range can the V18001A ferrite core adapt to? A4: Adopting high-quality VN09 ferrite material, the product has a Curie temperature above 130℃, with stable physical and electrical properties in conventional equipment operating temperature environments. It can adapt to long-term continuous operation of household and industrial electronic equipment.

Q5: Why do certified finished products still need to add ferrite cores after mass production? A5: Laboratory single-machine testing has a clean electromagnetic environment, while actual household and engineering environments have complex superimposed interference from the power grid and surrounding equipment. Adding ferrite cores can further improve anti-interference redundancy and ensure stable EMC indicators in actual application scenarios.
