Product Description

This high-performance EMI ferrite core is professionally engineered to suppress electromagnetic interference across diverse electronic devices and circuits. Adopting premium-grade materials and precise manufacturing techniques, this EMI choke core delivers superior noise reduction performance, effectively optimizing electromagnetic compatibility and stabilizing the operation of electronic equipment. Featuring robust structural design and consistent magnetic characteristics, it maintains reliable working performance even in complex and rigorous application environments, greatly improving circuit efficiency and operational stability.

Crafted from high-stability VN19 ferrite material, this core achieves a rated initial permeability of 1600. Such excellent magnetic permeability enables the component to rapidly absorb and dissipate high-frequency noise signals, effectively restraining stray electromagnetic interference within circuits. The VN19 material features outstanding thermal stability and electrical consistency, ensuring steady magnetic output despite frequent temperature changes and fluctuating electrical loads during long-term operation.

The core is designed with a remanence value of 360, representing stable residual magnetization capacity after external magnetic field removal. Moderate residual magnetism effectively sustains continuous noise suppression without causing magnetic saturation or signal distortion, guaranteeing pure and stable signal transmission.

With a coercivity rating of 30, this ferrite core features excellent demagnetization resistance. It can complete fast magnetization and demagnetization responses following electromagnetic field changes, ensuring efficient wide-spectrum EMI filtering and enhancing the overall operational reliability of terminal electronic products.

Equipped with a low relative temperature coefficient ranging from 1 to 3, the core possesses outstanding thermal stability. Its magnetic parameters will not drift significantly under variable temperature conditions, avoiding performance degradation in fluctuating working environments. This advantage makes it highly adaptable for automotive, industrial and consumer electronic scenarios with strict temperature requirements.

Featuring a practical sleeve structure, this ferrite EMI core supports flexible and convenient installation. It can be directly sleeved on various signal lines and power cables to block high-frequency noise transmission and prevent interference diffusion inside the system, effectively upgrading the electromagnetic compatibility of finished equipment.

To sum up, the VN19 ferrite core model V18017FS with 1600 initial permeability, 360 remanence, 30 coercivity and 1-3 temperature coefficient is a premium EMI suppression solution. With stable magnetism, strong temperature adaptability and easy assembly, it serves as an essential passive component for electronic engineers to optimize circuit performance and eliminate electromagnetic interference.
