According to the search results, the inductor product line of Maijie Microelectronics (Maijie Technology) covers multiple technical directions and application scenarios, and its series division is mainly based on dimensions such as process structure, material characteristics, application fields, and performance parameters. The following is a comprehensive classification and characteristic analysis of its inductor series:
1、 Classified by process structure
Integrated power inductor
Technical features: Using metal soft magnetic materials (such as alloy magnetic powder or nanocrystalline magnetic powder) and low-temperature co firing technology (LTCC), it has the advantages of small size, high current carrying capacity (supporting high current), strong resistance to electromagnetic interference, low impedance, and stable temperature rise. For example, its patented technology improves heat dissipation performance and high-frequency response through multi turn flat wire winding and magnetic core bracket design.
Application scenarios: Widely used in the fields of smartphones (such as over 50% of Samsung AI phones), AI servers (such as Nvidia GB200, each requiring 300 chips), automotive electronics, etc. Among manufacturers in Chinese Mainland, the number of shipments is the first, and the market recognition is high.
Wound power inductor
Subdivision types: including traditional winding and side welding winding. The latter optimizes the magnetic core structure and flat wire winding process by welding the coil leads to the side of the magnetic core, reducing height restrictions and lowering direct current resistance (DCR), increasing saturation current (Isat) and temperature rise current (Irms).
Advantages: The flat wire winding technology makes the wiring denser and the cross-sectional area of copper wire larger, suitable for high-temperature stability requirements in micro devices (such as smartphones) and industrial control fields.
Stacked chip inductor
Process and Performance: Based on LTCC technology, high bandwidth characteristics (suitable for 5G communication base stations and mobile phone terminals) are achieved through high-precision printing and low-temperature sintering processes, while low high-frequency loss supports fast signal processing.
Market positioning: Occupying a technological advantage in 5G high-frequency scenarios and leading the domestic market share.
2、 Classified by material
Ferrite inductor: Made of NiZn ferrite material with excellent magnetic properties, suitable for high-frequency applications such as communication base stations.
Aluminum alloy inductor: Strong heat dissipation performance, suitable for high-power demand scenarios (such as electric vehicle charging stations).
Polymer inductance: Lightweight and flexible design, suitable for portable devices such as smartwatches.
Metal soft magnetic material inductance: mainly composed of integrated inductors, with a saturation magnetic flux density more than twice that of ferrite, capable of withstanding high currents and having a smaller volume.
3、 Classified by application field
Consumer Electronics Series
Mainly using integrated inductors, it meets the miniaturization and high-performance needs of devices such as smartphones and tablets, with a single phone usage of about 20 pieces.
New Energy and Automotive Electronics Series
High current inductors (such as patented wound inductors) are used in photovoltaic inverters and car chargers to enhance system safety and charging efficiency.
Communication equipment series
Stacked LTCC inductors are used in 5G base stations and RF front-end modules, with significant high-frequency characteristics.
Industrial Control Series
Due to its outstanding high-temperature stability and surge resistance, wound inductors are suitable for scenarios such as power converters and servo motor drives.
