Verified Soft Ferrite Core Supply for Industrial Power Electronics

Velinda Technology Company operates under the Velinda Magnetics brand, focusing on soft ferrite cores, magnetic materials and application-oriented sourcing support for global industrial customers.

We supply and support a wide range of soft magnetic products, including MnZn ferrite cores, NiZn ferrite cores, transformer ferrite cores, inductor ferrite cores, EMI suppression ferrite cores, EE ferrite cores, EI ferrite cores and RM ferrite cores.

Our products are widely used in power electronics, automotive electronics, EV charging systems, solar inverters, energy storage systems, data center power, industrial power supplies, wireless charging, EMI suppression and magnetic component manufacturing.

Our Positioning

Velinda Magnetics is not a low-price component trading website.

We focus on verified material sourcing, technical documentation support, project validation and stable industrial cooperation.

For professional buyers, ferrite core purchasing is not only about price. Material stability, core loss performance, dimensional consistency, documentation, batch reliability and long-term supply capability are often more important.

Our goal is to help industrial buyers reduce sourcing risk and improve project efficiency by providing reliable magnetic material supply and clear technical communication.

What We Supply

Our product range includes:

• Soft Ferrite Cores
• MnZn Ferrite Cores
• NiZn Ferrite Cores
• Ferrite Cores for Transformers
• Ferrite Cores for Inductors
• EMI Suppression Ferrite Cores
• EE Ferrite Cores
• EI Ferrite Cores
• RM Ferrite Cores
• Custom Magnetic Core Solutions

We support both standard product inquiries and project-based sourcing requirements based on drawings, part numbers, material specifications and application scenarios.

Material and Application Focus

Soft ferrite materials are widely used in high-frequency power conversion and electromagnetic control applications. Compared with many metallic magnetic materials, soft ferrites offer high electrical resistivity, which helps reduce eddy-current loss in high-frequency applications.

Velinda Magnetics focuses on materials and products used in:

• High-frequency transformers
• Switching power supplies
• DC-DC converters
• EV charging systems
• Solar inverter systems
• Energy storage converters
• Server and data center power systems
• Common mode chokes
• EMI filters
• Wireless charging modules
• NFC and RFID applications

Verified Sourcing Support

We work with qualified magnetic material supply resources and support customers with verified soft ferrite material sourcing for industrial projects.

For qualified projects, we can support material documentation, specification review, sample coordination and sourcing communication. When customers require specific material systems or cross-reference materials, we can help review available options based on application requirements.

Our sourcing support covers MnZn power ferrite materials, MnZn high-permeability ferrite materials and NiZn ferrite materials for different power, filtering and EMC applications.
