Fixed Inductors

Fixed inductors are passive two-terminal electrical components that store energy in a magnetic field when electric current moves through them. They have an electrical resistance that does not vary over time or with temperature. As a result, they are commonly used in power supplies, amplifiers, and other electronics. The 0402-11NK application field is applicable to circuits where auto-transformer control is needed, such as electric power supplies. With a coil size of 0402 and measured inductance of 11nH, this fixed inductor can be used as a noise filter, a charge pump, an RF cross-connect, or a low-current transformer with secondary windings, all of which are essential functions for supplying and regulating phantom power as well as allowing for switching capabilities in many electronic circuits.When electricity runs through the 0402-11NK inductor, it creates a magnetic field which stores energy and helps to regulate current and voltage. The following is an explanation of the basic working principle behind the 0402-11NK inductor:When current flows through a wire, a magnetic field is created around the inductor. By adjusting the number of turns in the coil, the amount of current that can flow through the inductor can be adjusted. If the magnetizing force is increased, more current will flow through the coil than if the magnetizing force was decreased. The induced voltage, or the voltage that is induced due to the changes in the magnetizing force, works to oppose the changes in the magnitude of the magnetic field. This principle is known as Lenz’s Law and dictates that the induced voltage always opposes the change in the magnetic field.In the 0402-11NK inductor, the induced voltage allows for current regulation throughout different levels of voltage. With the help of the 0402-11NK inductor, the current can be regulated by varying the voltage, helping to ensure stability in the circuit. The 0402-11NK is a highly reliable inductor with a tolerance of 5%, allowing for a higher degree of accuracy and stability. It also features a wide inductance range of 1nH to 500nH and a low DC resistance of 0.2Ω, showing its great capabilities as a noise filter. The 0402-11NK is also RoHS compliant and has a high thermal shock rating to ensure that it is able to withstand the most extreme conditions. In conclusion, the 0402-11NK fixed inductor is an essential component for any electronic device, providing optimal performance in terms of power regulation and protection. Its working principle is based on Lenz’s Law, which enables it to regulate current using induced voltages that work to oppose the changes in the magnetic field. With its reliable tolerance of 5% and a low DC resistance of 0.2Ω, the 0402-11NK inductor is an excellent choice for any electronic application.
