Fixed Inductors play a significant role in virtually all types of electronic and electrical applications. They are especially important in circuits where high amounts of current need to be regulated, such as supplies to high power components, voltage regulators and amplifiers in audio and video systems. As such, they are critical components in circuits such as speakers, set-top boxes, and large industrial power systems. As one of the major suppliers in the market, the PM20-390K Inductor is one of the most reliable and widely used devices in its category.

The PM20-390K fixed inductor comes with a nominal inductance of 390 microhenries in a single-layer, 2 mm x 2 mm leaded package. It is manufactured using a process of thin-film deposition on a ceramic substrate and is designed to provide high current handling capability and excellent inductance stability with temperature. Its reliability is further enhanced by the use of a robust thermally stable design and a wide operating temperature range. The device can handle up to 3.3 amps of continuous current and maintains a tolerance of ±0.5%.

The PM20-390K is also a high frequency fixed inductor and can operate over a range of frequencies from 1 kHz to 1 MHz. It is particularly well suited for high speed switching applications, where quick response times are needed. Additionally, the device features low resistance and high Q-Factor (efficiency ratio) for high-quality inductor performance. It also has a low DC resistance which helps improve performance in a wide range of applications, from voltage regulation to audio/video systems.

The main working principle of a fixed inductor is based on the concept of inductance, which is the ability of a wire or coil to store electrical energy. This energy can be released quickly in the form of a current when a voltage is applied to the device. The inductor works by creating an alternating magnetic field that induces a current in the surrounding circuits. This current generates a counter-electromotive force, which is opposed to the applied voltage. As a result, the energy stored in the coil is able to regulate the current in the circuit.

The inductance of the PM20-390K fixed inductor can be adjusted by means of a capacative tapped hole. This allows for a range of applications, including voltage regulators, high frequency converters, and motor controllers. Additionally, its tight tolerance and excellent inductance stability in high-temperature applications make it ideal for use in high-power switching applications. The inductor also features a wide range of impedances and inductance coefficients, making it suitable for a variety of other applications.

The PM20-390K inductor is one of the most reliable and widely used inductors for a variety of applications. Its excellent current handling capability and wide operating frequency range make it suitable for a variety of different applications. Additionally, its robust design and high efficiency ratio make it an ideal choice for high-power switching and high speed data transfer applications. Its versatility and high-quality performance make it a great choice for a wide range of applications.
