Fixed Inductors

Fixed inductors, also known as choke coils, are theoretically passive elements that introduce inductance to block a continuous flow of direct current (DC) while allowing an alternating current (AC) to pass, while also providing a path of low resistance for the AC current. The main components of the fixed inductors are inductors, windings and a magnetic core. This type of inductor is most commonly used for signal filtering applications and as components in radio frequency (RF) circuits.

103-122K Application Field and Working Principle

The 103-122K inductors are specially designed for use in automotive applications such as power converters, speed controllers, filters, etc. These inductors are designed to meet the stringent requirements of the automotive industry, such as vibration, temperature capacity and stability. The inductors are also able to withstand high operating temperatures and are able to operate in harsh environments.

The working principle of the 103-122K inductors is based on Faraday’s Law. According to Faraday’s Law, an inductor will create an induced voltage when the rate of change of current changes. This induced voltage is equal to the rate of change of current multiplied by the inductance of the inductor.

When a voltage source is connected to an inductor, the current will initially increase in a linear manner according to Ohm’s Law. However, once the desired current is reached, the rate of change of current will slow down due to the induced voltage. This creates an induced current opposite in direction to the main current, resulting in a total current that is lower than the initial value. This decrease in current is known as inductance.

The 103-122K inductors are equipped with electromagnetic cores which act as a way to increase the inductance of the winding. The cores are usually made of ferrite or iron-based material. The way the core works is by having the magnetic field from the alternating current pass through it. This makes the core act like an electromagnet, which increases the induced voltage and thus the inductance of the winding.

The 103-122K inductors are designed with high reliability, efficiency, and EM compatibility, making them ideal for automotive, industrial, and other applications. They are able to operate at temperatures ranging from -40°C to +125°C, and are able to handle peak currents up to 40A, making them ideal for automotive applications.

The 103-122K inductors are available in various sizes and shapes and are designed for a variety of applications. These include filters, DC to DC converters, speed controllers, switching regulators, and other inductors.
