Fixed inductors, commonly known as "chokes", are used to store energy in an electric field, to provide a current path with impedance or reactance, and in noise suppression circuits. In the power supply filter and rectifier output filter circuits, one kind of inductors, called "Common Mode Chokes", can be used to reduce the electromagnetic noise from the power line. The LQG15 series fixed inductors are one type of Common Mode Chokes used for EMI/EMC radiation control of AC power input and power output.

The LQG15WH1N2S02D is a Common Mode Choke from the LQG15 series that is characterized with a 25A rated current for saturation voltage. It is made of high performance ferrite cores and a high quality spool wire. It has a high winding ratio and adopts thick film processing. It is suitable for switching power supplies, frequency converters, inverter, PFC circuits, EMI filters, and other AC power supply equipment.

The primary working principle of the LQG15WH1N2S02D is that the inductor produces an opposition to the changes in current, so as to oppose the induced current that creates the electromagnetic field. Specifically, its inductance is proportional to the square of the current that passes through, and the opposition to changes in the current is proportional to the inductance. This opposition to changes in current reduces the energy that is radiated from the power line. Furthermore, the ferrite core is designed to increase the inductance of the choke and reduce the overall size and weight.

Overall, the LQG15WH1N2S02D is an excellent choice for applications that require energy or signal storage, current path resistance, or noise suppression. It is characterized with lower power loss, low temperature rise, and high saturation current capacity, making it ideal for power supply, frequency converters, and other AC supply power equipment.
