Fixed inductors are one of the most commonly used components in electronic circuits. They are part of a variety of electronic devices and are used to store energy. The PM40-820K is a specialized type of fixed inductor designed for use in high powered applications. This article will provide an overview of the application field and working principle of the PM40-820K.

Application Field

The PM40-820K is a type of radial fixed inductor that is designed for use in high power DC/DC converters, board-level power supplies, and chargers. It is a high-power, low-cost inductor with a wide range of inductance values that can be used in a variety of applications. The PM40-820K\'s high power rating allows it to be used in applications that require a high current draw without the need for additional heatsinking.

The PM40-820K is ideal for high power DC/DC converters, step-down converters, and switched-mode power supplies. It can handle high peak currents without saturation, and its low profile package saves space in circuits. The PM40-820K is also well-suited for low-noise applications due to its low ESR values.

Working Principle

The working principle of the PM40-820K fixed inductor relies on Faraday\'s law of induction. This law states that a changing magnetic field will cause a voltage to be induced in a conductor that is positioned within the field. The coil of wire inside the PM40-820K is the conductor, and when a current passes through it, a magnetic field is generated. This magnetic field will induce a voltage that is proportional to the number of turns in the coil and the speed at which the current is changing. This induced voltage can then be used to power other circuits.

The PM40-820K is designed to be used in high-power applications and has a high saturation current rating. This means that it can handle large currents without becoming saturated. When the current is increased beyond the saturation point, the inductor will no longer be able to generate a voltage proportional to the current, and its inductance decreases drastically. This makes the PM40-820K ideal for applications that require high current or a high-power load.

Conclusion

The PM40-820K fixed inductor is a specialized type of radial inductor that is designed for use in high power applications such as DC/DC converters, board-level power supplies, and chargers. It is a high-power, low-cost component with a wide range of inductance values that can handle large peak currents without saturation. The PM40-820K operates on the basic principles of Faraday\'s law of induction, and it can be used to generate a voltage to power other circuits.
