With the development of the electronics industry, electronic products have begun to show the development trend of “four modernizations”, namely miniaturization, integration, multi-function, and high-power. In order to comply with the popularization of electronic products, the electronics industry urgently needs an inductance product that is small in size, high in power, low in cost and suitable for integrated installation. One-piece inductors appear.

Advantages and disadvantages of integrated inductors
One-piece inductors, also called “alloy inductors” or “molded inductors”, include a base body and a winding body. The base system is formed by die-casting the winding body by embedding the winding body into the metal magnetic powder. There are two types of integrated inductors, DIP and SMD, and they are all die-casting, which require relatively high powder insulation treatment. At present, the mainstream materials on the market are alloy iron powder. Good material properties and special structural design make the inductor structure more stable, lower impedance, and better seismic performance, so it has a higher conversion efficiency.

Compared with traditional inductors, one-piece inductors also have the following advantages:
1. Magnetic shielding structure, closed magnetic circuit, strong anti-electromagnetic interference, ultra-low buzzing, and high-density installation.
2. Low-loss alloy powder die-casting, low impedance, no lead terminal, small parasitic capacitance.
3. One-piece structure, solid and firm, accurate thickness of the product, and anti-rust.
4. Small size and large current, it can still maintain excellent temperature rise current and saturation current characteristics under high frequency and high temperature environment.
5. Exquisite selection of materials, fine workmanship, and wide working frequency coverage (up to 5MHz or more).
shortcoming:
The workmanship is more complicated than traditional inductors and requires very sophisticated inductor production equipment and technology, so inductor production costs are relatively high.
However, in recent years, with the improvement of manufacturing technology and large-scale investment in production equipment, the price of integrated inductors has gradually become civilian.
