Fixed inductors are components designed to maintain a constant inductance value when a secondary electric current is applied. This property makes it very useful in many electronic circuits, allowing for high-frequency resonant circuits or voltage-controlled capacitors. The LAL04NA391K is one such fixed inductor, which is widely used for various electronic applications.

The LAL04NA391K is an enclosed fixed inductor with an integral shield and high saturation current characteristic. It has a high-frequency impedance which is relatively low for a fixed inductor, with a self-resonant frequency of approximately 2.2MHz. This makes it ideal for applications such as radio frequency (RF) circuits, as it can effectively block unwanted frequencies and minimize the interference of signals in resonance circuits.

The LAL04NA391K also features an effective temperature coefficient of 1% – 4%, meaning it is better to maintain its inductance curve in temperature-sensitive applications. The maximum inductance value is 3300nH, with a maximum DC current rating of 2.8A. The total resistance of this inductor is just 11.5mOhms, which is very low.

As far as working principle is concerned, the inductor works on the principle of Faraday’s Law of Induction. This law states that when there is a change in current in a conductor, there is an induced electromotive force (EMF) which is proportional to the rate of change of the current. In other words, when a conductor is placed in a changing magnetic field, an EMF is induced in the circuit. In the LAL04NA391K, the magnetic field is produced by the current flowing through the windings, causing an EMF to be induced. This EMF is what causes the inductance properties of the inductor, allowing it to serve as an effective filter for unwanted frequencies or signals.

The LAL04NA391K is an important component for designing various electrical circuits. It is mainly used in automotive, automotive electronics, medical equipment, power supplies, power converters, microwave devices, and telecommunications applications. It is very reliable in these applications, thanks to its high-frequency impedance and low-temperature coefficient design.

In conclusion, the LAL04NA391K is an enclosed fixed inductor which works on the principle of Faraday’s Law of Induction. It is both reliable and efficient in temperature-sensitive applications and is widely used for various electronic applications such as automotive, medical, power supply, and telecommunications applications.
