Key Features
Insulated Particle Surface
Each particle carries a high-resistivity coating to suppress eddy currents.
High Electrical Resistivity
Dramatically lowers AC losses in high-frequency environments.
Excellent Moldability
Supports high compaction forces while maintaining coating integrity.
Stable Magnetic Characteristics
Ideal for power inductors, molded cores, and 3D-magnetic-path structures.
Adjustable Particle Size
Multiple size options for balancing inductance, permeability, and mechanical strength.
High Mechanical Durability
Produces dense and robust cores ideal for vibration-heavy automotive environments.
Material Technology
Each iron particle is coated with a thin, uniform dielectric layer engineered to withstand high compaction pressures while maintaining electrical separation between grains. During pressing, the coating maintains integrity, ensuring excellent high-frequency magnetic behavior after heat treatment.
Particle sizes can be customized (typically 10–60 μm), providing designers flexibility for low-frequency energy storage cores or high-frequency power conversion systems such as onboard chargers, DC-DC converters, and high-efficiency electromobility components.
Benefits
- Reduced Eddy Current Loss: Enables high efficiency even in fast-switching power applications (SiC/GaN-based systems).
- Compact 3D Flux Paths: Allows magnetic circuits impossible with laminated steel or ferrite blocks.
- Lower Component Weight: High-density compaction enables smaller, lighter inductors and chokes.
- Thermal Stability: Suitable for electronics operating in 150–200°C environments.
- Low Audible Noise: Reduced magnetostriction compared to ferrites, ideal for EV applications.
Applications
- Molded inductors for compact electronics
- EV power supply systems (OBC, DC-DC)
- High-efficiency power chokes
- Magnetic components for SiC/GaN fast-switching circuits
- High-frequency transformers and energy storage inductors
- 3D magnetic path devices used in automotive, telecom, and industrial power
This insulated soft-magnetic powder is a key material enabling next-generation power electronics, high-frequency energy conversion, and compact, high-density magnetic designs.
Summary
NEWLIFE Insulated Soft Magnetic Powder is a specialized iron-based magnetic material engineered for applications requiring low eddy-current loss, high electrical resistivity, and stable magnetic behavior at medium-to-high frequencies. Compared with traditional soft-magnetic iron powders, this material includes a uniform insulating coating on each particle, significantly reducing inter-particle eddy currents and improving overall energy efficiency.
This insulation design makes the powder ideal for 3D-flux magnetic circuit structures, molded inductors, powder cores, and automotive power electronics where conventional laminated materials or ferrites fall short.
