Fixed Inductors

An inductor is an electrical component that stores energy in a magnetic field. It accepts an alternating current and creates a magnetic field around it that opposes the flow of the current. This opposition causes the inductor to behave like a resistor, attenuating the current, and producing a voltage drop across the inductor, when the current is in a steady state. This property makes inductors useful in a variety of electronics applications, such as filters, and for smoothing out current flow in switching power supplies.The LQH2MCN100K02L is a fixed inductor that is primarily used in DC-DC converter applications. It can handle up to a maximum of 100 kHz, and has an inductance value of 10 nH. It also has a relatively low DCR at 18 mohms, and is rated to operate in a temperature range between -40 degree Celsius and +125 degree Celsius.The primary application of this part is as a power supply filter inductor in DC-DC converters, but it can also be used in motor control circuits, and as a switch for a power supply. For its size and weight, it has a relatively high current rating, up to 2.2 amps, withstanding a maximum surge of 10 amps for a few seconds.

Working Principle

The working principle of the LQH2MCN100K02L is based on electromagnetic induction, a phenomenon discovered by Michael Faraday in the 19th century. This is basically the production of electric current in a conductor when it is exposed to a varying magnetic field.In a typical application for this inductor, the current input to the device is in the form of an alternating current. This current causes a magnetic field to be created inside the inductor, which opposes the influx of current. The opposition of this magnetic field to the current flow causes a voltage drop, which acts as a filter to the DC-DC converter, preventing sudden surges in current from destabilizing the system.Due to its high saturation current rating, the LQH2MCN100K02L is particularly useful as a filter inductor for high-load applications. It is also very beneficial when used in low-load applications, where its high current rating allows for a tighter and more efficient regulation of current.

Conclusion

The LQH2MCN100K02L is a fixed inductor primarily used in DC-DC converter applications. It has a high current rating, up to 2.2A, withstanding a maximum surge of 10A for a few seconds, and a relatively low DCR at 18 mohms. Its working principle is based on electromagnetic induction, which results in voltage drop that acts as a filter to the DC-DC converter. Due to its high saturation current rating, the LQH2MCN100K02L is particularly useful as a filter inductor in high-load and low-load applications.
