Fixed inductors, such as the ELJ-SA390KF, are passive components in electronic circuits. They are generally used as components in an electrical circuit that stores energy by forming an inductive loop. Inductors oppose any change in current and can be used to filter or reduce high frequency signals. This article will discuss the application field and working principle of ELJ-SA390KF fixed inductors.

ELJ-SA390KF fixed inductor is a single-layer core with a coil diameter of two millimeters. The inductance value of this type of inductor is approximately 390nH at 3MHz DC resistance of 11Ω or less, and its rated current range is 0.1A-0.2A. The inductance value of ELJ-SA390KF fixed inductor is very stable, and its self-heating loss is very small. This type of inductor can withstand a high temperature of 125°C and meets the AEC-Q200 qualification standards.

The application field of ELJ-SA390KF fixed inductor is very wide. It can be used in various electronic circuits to adjust the working frequency, improve accuracy, filter noise, suppress high frequency interference signals, overcome dynamic impedance and reduce mutual interference. It is particularly suitable for high frequency circuits such as communications, automobiles, home consumer electronics, and network communication products, and is very popular in the industry.

The working principle of ELJ-SA390KF fixed inductor is based on the basic principle of electromagnetic induction. When a current is applied to the metal loop of the inductor, a magnetic field will be generated. This magnetic field is capable of inducing electromotive force in the metal loop. Thus, electric current passes through the inductor and energy is stored in the metal loop. The energy stored in this metal loop is called inductance, which is denoted by the symbol \'L\'. The higher the inductance, the greater the amount of energy stored and the stronger the resistance to current change.

In addition, the loading capacity of the ELJ-SA390KF fixed inductor is also excellent. The most common loading capacity metric is the “Q” factor. The higher the Q factor, the higher the loading capacity. ELJ-SA390KF fixed inductors are equipped with excellent Q factors, making them able to withstand large currents and voltage peaks, and excellent load performance.

To sum up, the ELJ-SA390KF fixed inductor is a widely used and efficient passive component in various electronic circuits. It has a wide application field, excellent working principle, stable inductance and excellent quality and loading capacity, and is particularly suitable for high frequency circuits such as automobiles and communications.
