Fixed inductors, known as also coils or chokes, are passive electronic components used to store energy in the form of magnetic flux. They are found in virtually all types of electronic equipment from radios to televisions, computers, aviation electronics, music systems and communication devices. Fixed inductors are extremely important components in their own right since they contribute to a device’s functionality in many ways, from signal processing to controlling current levels.

The VLS4012ET-2R2M-CA is a surface mount, molded power inductor with a wide range of application fields. It has a compact, 0402 package which makes it ideal for space-restricted applications such as notebooks, tablets, smartphones and other mobile devices. It has a high current rating of 2.2A with an inductance of 1.2uH and a saturation current of 3.6A. It is capable of operating in temperatures up to +125°C.

Wondering how does a fixed inductor like the VLS4012ET-2R2M-CA work? It works on the principle of Faraday\'s law of induction. According to this law, when a conductor passing through a magnetic field, a current is induced in the conductor. This current is proportional to the rate of change of magnetic flux. The magnetic field induces a voltage in the conductor which is proportional to the rate of change of flux. This voltage can be used to generate a current in the same direction as the flux.

The VLS4012ET-2R2M-CA fixed inductor is mainly used for power supply line filtering, as a signal line noise filter, and for power line EMI suppression. It is most suitable for buck and boost switching regulators, synchronous rectification circuits, DC-DC converters, switch mode power supplies, consumer electronics etc. During the operation of a switching regulator, current flows through the inductor to the load and back to the regulator, and the inductor helps to reduce the noise and ripple on the output voltage.

The VLS4012ET-2R2M-CA inductor has a low DC resistance which helps to reduce conduction losses associated with the power circuit. The inductance and saturation current provide excellent performance when used in high-frequency applications and switching power systems. Furthermore, its molded case helps it to withstand high levels of vibration and shock, making it highly reliable and suitable for even demanding applications.

These features of the VLS4012ET-2R2M-CA fixed inductor make it suitable for a wide variety of applications including telecommunication equipment, ultrasonic productions, automotive, medical devices and home appliances. Its small size and high current rating make it ideal for high-power applications like electric vehicles, power conversion modules, and more. This makes the VLS4012ET-2R2M-CA one of the most powerful and reliable inductors on the market today.
