Fixed inductors, also known as fixed chokes, are passive electronic components that create a magnetic field with a single loop of wire wrapped around a core material. They are composed of two terminals which feed a current through the coil. This creates a constant magnetic flux in the coil, which in turn creates a constant magnetic field.

The 0819-40H is a type of fixed inductor that is designed for a wide variety of applications. Its copper clad steel construction makes it incredibly durable, making it ideal for high-reliability applications such as test and measurement equipment, medical instruments, and space applications.

The 0819-40H has an inductance range of 0.05 to 10.0 millihenries (mH) with a maximum DC current rating of 1.5 amp. It also has a high-Q rating of up to 50 at 10 kilohertz (kHz). This makes it ideal for filters, impedance matching, and tank circuits.

The working principle of the 0819-40H fixed inductor is based on Faraday\'s law of induction. According to this law, when a current is passed through a coil of wire, it produces an opposing current in the coil\'s secondary winding. This secondary current generates a magnetic field, which will oppose the primary current and will create a voltage across the coil\'s terminals.

As the current passing through the coil increases, the magnetic field in the secondary winding increases, thus resulting in a greater opposing voltage in the coil\'s terminals. This opposing voltage is what is known as inductance, and it provides effective filtering for AC and DC circuits.

In addition to being used as components in AC and DC circuits, the 0819-40H fixed inductor can also be used in a variety of applications from power supply filtering to antenna matching networks. It is also useful in the construction of RF antennas, transformers, and sensing circuits.

The 0819-40H fixed inductor is a popular choice amongst electronics engineers and hobbyists due to its durable construction and reliable performance. It provides effective filtering, impedance matching, and tank circuits in a wide range of applications and is a great choice for high-reliability applications.
