Fixed inductors are components that provide inductance in semiconductor circuits. The flow of current through the inductor produces a magnetic field that, in turn, creates voltage. This type of inductor usually contains a single loop of wire and can be found in a wide range of circuits. In this article, we’ll take a closer look at the PM43-390K-RC application field and working principle.

The PM43-390K-RC is a fixed inductor that is designed for a range of DC-DC converter applications. It has a high power handling capability, with a rated current of 39 amps and an operating temperature range of -40°C to +125°C. It has a self-resonant frequency of 3.2MHz and a high temperature stability of over 8% at 100°C.

The PM43-390K-RC is suitable for use in a wide range of circuits, such as the DC resistive switching of high power devices, DC-DC converter circuits, battery charge controllers, or switch-mode power supplies. It can also be used in high-efficiency solar inverters.

The PM43-390K-RC inductor works on the principle of Faraday’s law of induction. This law states that when a current-carrying conductor is placed in a changing magnetic field, a voltage will be induced in the conductor. This voltage is proportional to the rate of change of the magnetic flux, and is inversely proportional to the length of the conductor.

The PM43-390K-RC inductor consists of a single loop of wire, with a ferrite core. The conductor is wound around the core, creating a magnetic field around the wire. When a current is applied to the inductor, the magnetic field around the wire increases. This increased magnetic field induces a voltage in the coil, which is proportional to the rate of change of the magnetic field. This voltage can then be used in a circuit to perform various functions.

The PM43-390K-RC inductor is a reliable and efficient component for a wide range of applications. It offers high power handling, high temperature stability and a self-resonant frequency of 3.2MHz. It is designed to be used in DC-DC converters, battery charge controllers, and high efficiency solar inverters, and is suitable for operation in temperatures between -40°C to +125°C.
