Fixed inductors are electronic components that store electrical energy in their magnetic fields. They come in a variety of categories and sizes, and they serve different functions in electronic circuits. One of the most common types of fixed inductors is the PM7032S-4R7M. This inductor is often used in DC-DC converters, high frequency switching power supplies, amplifiers, and digital logic circuits.

Application Field

PM7032S-4R7M inductors are mainly applied in high frequency switching power supply circuits in various electronic products. These inductors have low DC resistance and high saturation current, which makes them ideal for use in high frequency switching power supplies and DC-DC conversion circuits. In addition, they are also widely used in amplifiers, digital logic circuits, and various applications of high-speed logic systems due to their low-cost and high efficiency.

Working Principle

PM7032S-4R7M inductors work on the principle of inductance, which is the phenomenon that occurs when an electric current flows through a wire. When an alternating current passes through the induction wire, a reverse current is induced, creating a magnetic field. This field interacts with the magnetic field of the coil, which then causes a voltage to be generated in the opposite direction. This voltage is then used as an inductive voltage to drive various electronic components.

The PM7032S-4R7M is a high frequency switching electronic component. This means that the inductors ability to generate voltage changes rapidly with a change in the frequency of the alternating current that passes through it. As the frequency of the current increases, the voltage generated by the inductor increases, which increases its overall efficiency. The inductors ability to generate high voltage at high frequency makes it an ideal choice for high-frequency switching applications.

In addition to its ability to generate high voltage at high frequency, the PM7032S-4R7M also has high saturation current. The saturation current is the maximum current that can flow through the inductor without its magnetic field being disturbed. A higher saturation current results in greater efficiency, and this inductor can easily handle currents up to 7A.

The PM7032S-4R7M also offers excellent temperature characteristics. It is designed to operate in a temperature range of -30° to +125°C, making it suitable for most applications. In addition, this inductor has an insulation resistance of 100MΩ, which ensures that electrical signals remain undisturbed even when operating in extreme temperature environments.
