Fixed Inductors are electrical components widely used in various types of circuits. They are classified as components consisting of one or several coils, and as being passive components, their primary task is to store energy in the form of magnetic field. IMC1812EBR12M is one kind of fixed inductors. It can work in numerous applications, and its working principle aids to understand better how the component works and also helps designers decide how to pick from various options available.

The structure of IMC1812EBR12M is made of three main parts including core, dielectric and plated coil. The core is made of high permeability material, which is wrapped by many turns of copper wire. The innermost part of the coil is filled with a polarized dielectric. This dielectric also helps to reduce the reactive loss and increase the operating efficiency of the component. The outside of the coil is coated with a temperature stable nickel-plated overcoat. This layer helps to protect the coil and enhance the mechanical robustness.

IMC1812EBR12M can handle high current surges up to 1.8A with a maximum inductance drop of less than 0.5%. It provides a high frequency rate of up to 200 MHz, low power loss and minimal heat dissipation performance. It also has a high Q factor, which can be further improved by utilizing the “DC yoke” technology that extends the frequency range up to 5 GHz.

IMC1812EBR12M is a widely used component in various applications. It can be used in DC/DC converters, LCD backlighting, FPV/UAV and wearables. It is suitable for RFID and HFID applications, high speed data communication, cell phone transmission, and a variety of power management and energy saving components. IMC1812EBR12M is also a widely used component for EMI/EMC and ESD protection.

The operating principle of IMC1812EBR12M can be explained by the Faraday’s law of induction. As the flux linkage rate increases, an induced voltage is generated in the inductor in the opposite direction of the load current. The induced voltage and current are relative proportionate to the rate of change in the flux linkage, so when the load current is reduced, an induced voltage is generated in the inductor which opposes the change of the load current.

IMC1812EBR12M acts as a smoothing filter in a power line in order to reduce power noise. It is also used for reducing signal noise in signal transmission lines by reducing fluctuation in the signal. It is used to increase the load holding capability of DC/DC converters. The inductor also reduces the voltage overshoot and ringing/oscillation caused by the parasitic capacitance combined with the circuit wire.

IMC1812EBR12M is a high performance and cost-effective fixed inductor from IMC Company. It has numerous advantages in various applications, such as, high current rating, low profile, high frequency range up to 5 GHz, high Q factor, low power loss, and minimal heat dissipation. It can be used in numerous applications, such as DC/DC converters, RFID and HFID applications, and EMI/EMC/ESD protection. Its operating principle is based on Faraday’s law of induction, and it can be used to reduce power noise and signal noise.
