According to the search results, the inductor product line of Maijie Microelectronics (Maijie Technology) covers multiple technical directions and application scenarios, mainly divided into the following categories:
1、 Classified by process structure
Integrated power inductor
Features: Small size, high current carrying capacity (supporting high currents), strong resistance to electromagnetic interference, low impedance and stable temperature rise, especially suitable for high-frequency application scenarios. For example, its integrated inductor adopts low-temperature co firing technology (LTCC) and casting process, which improves the DC bias characteristics and current resistance.
Application: Widely used in high-frequency and high-power scenarios such as AI servers (e.g. Nvidia GB200 chips require 300 chips/block), smartphones (e.g. Samsung AI phones with over 50% adoption), and consumer electronics.
Market position: the first manufacturer in Chinese Mainland in terms of shipment volume, and the industry leader in technical specifications.
Wound power inductor
Features: Adopting flat wire winding technology, dense wire arrangement, larger cross-sectional area of copper wire, reducing direct current resistance (DCR) and improving current capacity. Among them, the side welding winding technology optimizes the magnetic core structure, reduces height restrictions, and is suitable for micro devices.
Classification: including traditional winding and side welding winding.
Stacked chip inductor
Features: Based on LTCC technology, low high-frequency loss, supports fast signal processing, suitable for high bandwidth requirements of 5G communication base stations and mobile terminals.
Process advantages: Adopting high-precision printing and stacking technology, the size is smaller and the thickness is thinner.
2、 Classified by material
Ferrite inductance: Excellent magnetic properties, suitable for high-frequency applications.
Aluminum alloy inductor: Strong heat dissipation performance, suitable for high-power scenarios.
Polymer inductors: lightweight and flexible, suitable for portable devices.
Metal soft magnetic material inductance (such as integrated inductor): The saturation magnetic flux density is more than twice that of ferrite, it can withstand high currents and has a smaller volume.
3、 Classified by application field
Consumer electronics: smartphones, tablets, etc., mainly using integrated inductors to meet the needs of miniaturization and high efficiency.
New energy and automotive electronics, such as photovoltaic inverters and car chargers, rely on high current inductors (such as patented designs) to enhance system safety.
Communication equipment: 5G base stations use stacked LTCC inductors with significant high-frequency characteristics.
Industrial control: Wire wound inductors are used for power converters and servo motor drives due to their outstanding high-temperature stability and surge resistance.
AI server: The integrated inductor has become the mainstream solution due to its high current resistance and stability, and the usage of a single AI server is twice that of traditional equipment.
4、 Other classification dimensions
Current level
Low current: used for small devices such as mobile phone chargers.
Medium current: Balancing performance and cost, suitable for medium power sources.
High current: used for electric vehicle charging stations and industrial equipment.
Packaging form
Surface mount (SMD): Automated production friendly, space saving.
Pin packaging: Traditional design, easy to manually solder.
