The role of the flat coil

In the future, the development trend of "light, thin, short, and small" downstream electronic products will definitely determine the miniaturization and development of upstream electronic components. The one-piece molded inductor realizes the miniaturization of the inductor. It is an upgraded product of the wound inductor. It is very suitable for the DC-DC (direct current to direct current) power management module (PMU) of thin and light intelligent mobile terminal products. The main applications include mobile phones, automobiles, aviation, communications, and other fields.

The flat coil is a characteristic shape coil that uses non-traditional flat enameled wire and needs special winding equipment to process. It is mainly used in low-voltage DC-DC communication power modules that require low height and high currents, such as notebook computers, high-current power solutions, and other fields. As we all know, compared with ordinary coils, flat coils have the characteristics of light weight, high efficiency, and low noise under high voltage under the same volume; frequency, to obtain a higher Q value (quality factor); from the quality point of view, due to the simpler structure, the performance is more stable and the product consistency is better; in addition, because the temperature difference between the inside and outside of the coil is small, the heat dissipation performance and magnetic Efficiency Compared with ordinary coils, better performance can be obtained.

Since domestic complete machine companies tend to pay more attention to cost, if they can use ordinary substitutes, they will not adopt expensive new products, even if the performance of new products is slightly better. Therefore, due to the consideration of production cost, users objectively hinder the entry efficiency of flat coils in the domestic market. At the same time, the characteristics of the flat coil make it especially suitable for use in DC-DC power supplies that require low voltage and high current while requiring a small size. The future development trend of consumer electronics (such as laptops, PDAs, etc.) is smaller size and stronger functions. Run faster, which puts forward strict requirements on the corresponding power supply.
