Fixed Inductors

An inductor is a passive electronic component consisting of conductive material (usually a coil of wire) wrapped around a core that can store energy in the form of a magnetic field. Fixed inductors are those whose inductance does not vary significantly with frequency or temperature changes. A typical fixed inductor is the MLG0402P4N1BT000. This device has a variety of applications and working principles.

Working Principle of MLG0402P4N1BT000

The MLG0402P4N1BT000 is based on Faraday\'s law of induction. This states that an electric current will produce a magnetic field around it. The inductor works by using this principle. The current passing through the coil will produce a magnetic field around it. This field will be in the opposite direction of the applied current. This opposition of the current produces a voltage in the inductor, which is proportional to the rate of change of the current.

The magnitude of this induced voltage can be estimated by the equation V = L (di/dt), where L is the inductance of the coil. The MLG0402P4N1BT000 has an inductance of 4nH, which means it will produce an induced voltage of 0.4V when the current is changing at a rate of 10 mA/µs.

The inductor also has two terminals, labeled A and K. When connecting the inductor to a circuit, current will flow from terminal A to terminal K. It is important to note that the terminal A should always be at a higher voltage than terminal K.

Conclusion

The MLG0402P4N1BT000 is a versatile fixed inductor used in a variety of applications and working principles. Thanks to its low-losses design and exceptional frequency performance, it is widely used in the production of RF antennas, DC-DC converters, power supplies, mobile devices, and automotive electronics. Further, it can be used to store energy in the form of a magnetic field and to induce a voltage in the opposite direction of the applied current. The MLG0402P4N1BT000 is an ideal device for applications that require an inductor with a fixed inductance.
