Fixed inductors are electrical components used to store energy in an electrical circuit. The inductors are made up of wire that is wound around a core that is usually made of iron, aluminum or ferrite. The inductor will have two electrodes, one each at each end of the coil. When current flows through the coil, the magnetic field created will generate an opposing current that is perpendicular to the original current. This opposition current creates a back electromotive force, which can be used to reduce voltage, increase current and adjust the phase of the circuit.
The 0819-40K application field and working principle are primarily used to filter signals by blocking specific frequencies. This is done by allowing some frequencies to pass while blocking others. Depending on the inductance of the 0819-40K, inductors of different values can be used in combination to reduce the overall insertion loss of the circuit. In addition, the inductors can also be used to reduce output offset voltage or to prevent overshoot.
The working principle of the 0819-40K inductors relies on Faraday\'s law of induction. When current flows through the inductor, it creates a varying magnetic field which in turn creates an opposing current that is perpendicular to the original current. This opposing current is also known as a back EMF or counter EMF. This EMF will oppose the change in current, providing an impedance that can filter out or block unwanted frequencies.
The 0819-40K inductors are suitable for power line filtering, control loops, and general signal filtering. They are commonly seen in RF amplifier circuits, telecoms, computer peripherals, switches and automotive electronics. The 0819-40K also has low noise performance with good power efficiency.
Because the 0819-40K inductors are non-polar, they are suitable for use in AC applications. They are also easy to work with as they have low DC resistance and high saturation current. Furthermore, they are self-healing and have a low temperature coefficient, so they are well suited for applications with high temperature environments.
The 0819-40K inductors are normally used in a variety of applications across many different industries. Some examples include power conversion, motor controls, voltage regulation, signal filtering, switching functionality and more. The inductors are available in a wide range of values, from 0.1 to 100mH, with saturation currents ranging from 0.3A to 5A, and rated voltages ranging from 5V to 50V.
