Fixed Inductors

The MHQ0402PSA4N7JT000 is a type of fixed inductor. Fixed inductors are a kind of passive component, used in a variety of electronic and electrical circuits. They are generally used as filters or as part of a tuned circuit, to introduce inductance into the circuit. When current flows through the inductor, its windings create an electromagnetic field that induces a voltage in it.

Application Field

Fixed inductors are widely used in the field of electronic circuits. They can be used in pulse circuits to store energy, filter circuits to reduce noise, oscillator circuits to create waves, and decoupling circuits. In addition, they play an important role in power electronic applications, such as switching power supplies, boost and buck converters, and power inverters.

Working Principle

The working principle of a fixed inductor is quite straightforward. When a current flows through the inductor, the magnetic field of the laminations and windings induces a voltage on itself. The law of induction states that the induced voltage is proportional to the rate of change of the current, or the equivalent, the rate of change of the flux. Therefore, the generated voltage creates an opposing current which opposes the flow of the original current.

The opposition of current is directly proportional to the rate of change of the flux, and is inversely proportional to the inductance of the inductor. Thus, the greater the inductance of the inductor, the greater will be the opposition of the current and the higher will be the value of energy stored in the magnetic field.
