Fixed inductors are electrical components that, as their name suggests, are fixed in size and shape. They are used to store energy in a magnetic field and pass this energy to other components in a circuit. The HKQ04020N7C-T is a type of fixed inductor that is commonly used in power electronics applications.

The HKQ04020N7C-T is a ceramic core inductor with a high power inductance of 0.47 uH. It is characterized by low DC resistance, low magnetic saturation, and high power inductance. The product is rated for working voltage of up to 5V and can handle current up to 20A. The core material of the inductor is ferrite, which is one of the most common core material used in inductors due to its low cost and excellent electrical characteristics.

The primary application fields for the HKQ04020N7C-T fixed inductor include power supplies for high-end computing applications, power supplies for embedded machine control systems, and power amplifiers. In addition, it can also be used as an input inductor in a buck converter. In these applications, the fixed inductor is used to provide a stable current source.

The working principle of the HKQ04020N7C-T fixed inductor is as follows: the inductor stores energy in its magnetic field, which is generated by the current passing through its coil. When the current flow changes, the magnetic field changes with it, creating a voltage drop across the inductor. This voltage can be used to maintain the current in the circuit or to increase the current flow.

In addition, the HKQ04020N7C-T can also be used as an active filter element. In active filter applications, the inductor is used to regulate the amplitude of the desired signal, thereby eliminating unwanted frequencies. The inductor also reduces the transient voltage spikes that can cause damage to sensitive electronic components.

Overall, the HKQ04020N7C-T fixed inductor is an excellent choice for use in power electronic applications. It provides high power inductance, low DC resistance, low magnetic saturation, and a high working voltage. With its ability to maintain current stability and active filter capability, the HKQ04020N7C-T is an invaluable component for power electronics applications.
