Classification and Application of Inductance
With the rapid development and commercialization of 5G, the demand for inductors is constantly increasing. From the perspective of application fields, mobile terminals are the largest application market for inductors. The proportion of the total global market size has reached 50.6%. The main application markets of inductors include automobiles, household appliances, military industry, communication equipment and computers.
In the next few years, with the acceleration of 5G construction, the demand of the mobile terminal and communication equipment market will become the main driving force for the development of the inductor market. At present, more inductors used in the market include NR chip inductor, Tcore integrated inductor and common mode inductor.
NR chip inductor
NR chip inductors are also called automated shielding inductors because they are made by fully automated machines. It’s features include the use of magnetic glue coating structure, which greatly reduces noise. Strong drop impact resistance and durable. Under the same size conditions, the rated current is 30% higher than traditional power inductors. Small size, space saving and power saving.
Application product range: LED lighting, multi-function mobile phones, flat-screen TVs, Blu-ray DVDs, set-top boxes, notebook computers, desktop computers, servers, graphics cards, portable devices, personal navigation systems, multimedia devices.
Tcore Integrally formed inductor
Integrally formed inductors also called molded inductors, include a base body and a winding body. The base system is made by embedding the winding body into metal magnetic powder and die-casting. The SMD pins are the leads of the winding body and are directly formed on the surface of the base, this utility model has higher inductance and smaller leakage inductance than traditional inductance. The inductance is designed with SMD structure, which will not damage the inductance when in use, but also can improve the production efficiency.
Application product range: power supplies, computers, electronic equipment, military, medical, aerospace and automotive industries.
Common mode choke
Common mode choke is often used in computer switching power supplies to filter common mode electromagnetic interference signals. In the board design, the common mode choke also plays the role of EMI filtering, used to suppress the electromagnetic wave generated by the high-speed signal line from radiating to the outside.
The applied product range includes USB 3.0, DVI, HDMI and Serial-ATA high-speed differential signal equipment and interfaces in IT and communication equipment.

As one of the core parts of new energy vehicles, the electric drive system has an important impact on the performance of new energy vehicles, and has important significance for the power, economy, comfort, safety, reliability, and durability of new energy vehicles. In addition, in terms of industry needs, low cost, miniaturization, and intelligence are the main trends. The electric drive system of an electric vehicle is mainly composed of four parts: drive motor, transmission, power converter and controller. The drive motor is the core of the electric drive system, and its performance and efficiency directly affect the performance of electric vehicles. The size and weight of the drive motor and transmission will also affect the overall efficiency of the vehicle. Power converters and controllers can help electric vehicles operate safely and reliably.
In the long term, the trend of flat wire motors is highly certain. In the first half of 2021, the penetration rate of flat wire motors among the top 15 vehicle models in terms of sales reached 28%, compared to just 14% in 2020. It is anticipated that by 2025, the proportion of flat wire motors in the drive systems of new energy vehicles will exceed 80%.
X-Pin motor technology allows for a reduction in the height of the linear segment at the end of the motor while maintaining a high slot fill factor. This results in a shorter overall motor length, saving copper wire usage and improving motor efficiency, thus achieving miniaturization.
In recent years, the market penetration of new energy passenger vehicles has continued to rise. Due to the high demand, existing cylindrical-wire motors have become insufficient in meeting the performance requirements of electric vehicle propulsion. Therefore, the substitution of flat-wire motors for cylindrical-wire motors is a highly certain trend for the future. Motor manufacturers are actively seeking high-capacity, high-quality production processes to meet market demands, with ongoing optimization and innovation in the manufacturing processes of flat-wire motor stators.
As is well known, the energy conversion efficiency of electric motors is around 90%, meaning that losses account for approximately 10%. Within the energy losses of a motor, copper loss, which is the heat generated by the current passing through the stator winding, constitutes about two-thirds of these losses.By adopting flat wire motors, the round wire windings are replaced with flat wire windings, increasing the amount of copper per unit area on the stator. This increases the copper fill factor to 20% to 30%, meaning more copper is packed into the stator slots. This effectively reduces winding resistance, and the lower the resistance of the winding, the higher the electrical efficiency. Consequently, it reduces copper losses.
