Fixed inductors are crucial components in electronic circuits. The ELC-3FN2R2N is one type of fixed inductor. It is a 3-layer construction inductor that is surface-mountable in addition to having a flat top and bottom. It has an operating temperature range of -55℃ to +125℃ with an impedance range of 3.5MH to 16.8MH at 100KHz.

Flowchips\' ELC-3FN2R2N inductors have applications in various fields. Common uses range from power protection, LED lighting, home appliances, medical equipment and industrial automation, to automotive, military, aerospace and communications. It is widely used in demagnetizing circuits, high-frequency telecommunications, and impedance matching networks. It is also used for ripple protection of power supplies, audio amplifiers, and converters, and for the power supply of ICs.

The ELC-3FN2R2N inductors consist of three layers: the external visible layer, the external copper-clad layer, and the internal layer. The external visible layer consists of a tinned metal alloy lamination body that forms the outer covering. It is thermally stable to withstand temperatures ranging from -55℃ to +125℃. On the other hand, the external copper-clad layer is bonded to the external visible layer with a special non-corrosive adhesive that ensures the tightness of the coil. The internal layer is a multi-layer composite conductor with a low-permittivity dielectric in between the coils that helps reduce high-frequency losses.

ELC-3FN2R2N inductors use a combined series-parallel resonance circuit to reduce or eliminate the effect of the capacitance and inductance of the coil. This means that the inductor is able to store a much larger current than it would if it were just a single-layer inductor. Additionally, the series-parallel resonance circuit also improves the inductor’s frequency response. In fact, the ELC-3FN2R2N has a maximum DCR of 55mΩ and a self-resonance frequency of 400MHz stably regardless of temperature.

The ELC-3FN2R2N has a frequency dependent inductance. This is because the inductance of the inductor is dependent on the frequency of the current running through it. As the frequency goes up, the inductance goes down. This means that at higher frequencies, the inductance of the ELC-3FN2R2N is lower than it would be at lower frequencies. This allows for a wider range of applications as it can be used in higher frequency circuits.

The ELC-3FN2R2N is a surface mount fixed inductor that has a wide range of uses. It has a 3-layer construction that gives it an operating temperature range of -55℃ to +125℃, and it uses a combined series-parallel resonance circuit to reduce or eliminate the effect of the capacitance and inductance of the coil. Additionally, the ELC-3FN2R2N has a frequency dependent inductance which makes it suitable for higher frequency circuits. Overall, the ELC-3FN2R2N is a reliable and versatile fixed inductor that can be used in a wide range of applications.
