Fixed Inductors is used to increase the impedance in alternating current and low-frequency circuits. It can be divided into several types, such as choke, ferrite cores, adjustable inductors, etc. Among them, LD2-220-R is one kind of the products, which can be used in various applications.

The application field of LD2-220-Rcover power supplies, amplifiers, telecommunications, automotive electronics, and many other common electronic applications. It is widely used in various high-frequency circuits, such as those in consumer electronics, because of its excellent frequency characteristics. In addition, LD2-220-R also has the advantage of reducing the temperature rise of the device and improving efficiency.

The working principle of LD2-220-Ris based on Faraday’s Law of Electromagnetic Induction. It states that a current is induced in a coil when a variable magnetic field is present in the coil. This induced current produces a voltage in the coil, which can be utilized for various purposes. The magnetic field can be generated by a permanent magnet, an electromagnet, or an alternating current source. The current flow in the coil is proportional to the number of turns, so the inductance of the coil can be varied by increasing or decreasing the number of turns.

LD2-220-R is composed of high-quality magnetic steel core cores, which are wound into coils, and sealed in an epoxy resin shell. The indcutance of these products ranges from 0.2 to 2.2 uH and their internal resistance is generally between 0.1Ω and 1.5Ω. They can work in temperature ranges from -40°C to +120°C and offer excellent heat resistance and long life. They are easy to install and provide an highly reliable operation in the worse environmental conditions.

LD2-220-R can be used to adjust the voltage and current in a circuit, limit the peak current flow, increase the efficiency of a digital circuit, or isolate unwanted frequencies. They are generally integrated into circuits in regulated power supplies and audio amplifier circuits, and the exact type is determined by the specific requirements of the application.

In brief, LD2-220-R is a type of fixed inductor. It is widely used in consumer electronics and other electronic applications. Its working principle is based on Faraday’s Law of Electromagnetic Induction and its induction is related to the number of turns of the cores. It provides excellent stability and reliability, can work in extreme temperature ranges, and has a wide range of application field.
