Fixed inductors are passive components which are used to store energy in the form of magnetic fields. The 73F394AF is an example of such a device, designed for use in low-current and low-voltage applications. This article seeks to discuss the 73F394AF’s application field and working principle.

Application Field

The 73F394AF fixed inductor is designed for low-current and low-voltage applications such as 12V DC switched mode power supplies (SMPS), personal computers, and telecommunications devices. It is not recommended for use with higher voltages. Its small size and low profile make it ideal for applications where space is limited. The 73F394AF has a low loss and high stability, allowing for reliable operation in demanding environments.

Working Principle

The 73F394AF fixed inductor operates on a simple principle. It consists of an electromagnetic coil of wire, with a ferrite core, that is connected to an electrical circuit. When an electric current passes through the coil, a magnetic field is generated in the ferrite core. This magnetic field stores energy, which is released when the electric current is interrupted. This energy is used to amplify and convert signals, as well as to stabilize the voltage of a circuit.

The 73F394AF can also be used as a choke, allowing alternating current (AC) signals to pass, while blocking the passage of direct current (DC) signals. This is done by increasing the inductance of the device and slowing the rate at which the current changes. The inductance of the 73F394AF can be adjusted by altering the number of turns of wire around the ferrite core, or by changing the core material.

In addition to its use in low-current and low-voltage applications, the 73F394AF can also be used to dampen electromagnetic interference in sensitive devices. The inductive nature of the components helps to absorb any stray electromagnetic radiation that could otherwise interfere with the operation of the device.

Conclusion

The 73F394AF fixed inductor is an ideal choice for applications that require a low-profile and low-power component. It is capable of storing and releasing energy and is highly stable and reliable in demanding environments. Its ability to act as a choke also makes it suitable for controlling signal levels and dampening electromagnetic interference. As such, the 73F394AF can be used in a variety of low-current and low-voltage applications.
