Fixed inductors, or also known as inductors or chokes, are passive two-terminal electrical components used to store energy in a magnetic field. The IM04EB3R3K type of fixed inductors, in particular, is a high-frequency inductor which is designed to reduce EMI when used in high-frequency switching power supplies.

IM04EB3R3K inductors are designed to optimise the performance of high-frequency switching power supplies in various applications such as notebook computers, portable gaming systems, and digital TVs. IM04EB3R3K inductors have a wide range of inductance values which enables it to achieve higher switching speeds. The core material is made of nitride-treated ferrite, making them suitable for high frequency applications and gives them excellent heat dissipation.

The main purpose of an IM04EB3R3K inductor is to reduce EMI levels in the frequency range of 30MHz to 1MHz, and to do this efficiently, it must fit a range of circumstances, specifically the circuit specifications, the ambient environment of the circuit, and the electrical-magnetic fields which may interfere with the signal. In high-frequency switching power supplies, the IM04EB3R3K inductor works by decreasing the peak harmonic current in the power supply circuit. This is achieved by using a mu-metal core to absorb the magnetic field.

The working principle of the IM04EB3R3K inductor is based on Faraday\'s Law of Induction. When current flows through a conductor, a magnetic field is formed around it. When this magnetism passes through the IM04EB3R3K component, a constant voltage drop is applied to the current, called back-EMF (electromotive force). This is why the inductor is also referred to as an EMI filter. The back-EMF converts the energy in the current back into energy, thus reducing the peak harmonic current. This also helps to improve the efficiency of the power supply.

The IM04EB3R3K inductor is the ideal choice for high-frequency applications as it is designed to withstand high temperatures, is extremely durable, and has low magnetic distortion. It is also highly efficient with minimal internal losses, allowing maximum current to pass through it. For these reasons, IM04EB3R3K inductors are used in a wide range of electronic circuits including notebook computers, gaming systems, and digital TVs.
