9220-15

Fixed inductors are passive components which are used to store energy in the form of a magnetic field. They are used in applications which require a constant current or output from a device. The induction coil is usually made with a wire wrapped around an iron core, with the bobbin providing the physical support. The inductors draw energy from the power supply and help shape the current waveform without a significant voltage dropback. They act as inductance elements and are often used in combination with resistors and capacitors for controlling current, voltage, and resistance in a circuit.

In the case of the 9220-15, the inductor is a fixed, air-core coil with an inductance of 9.22 mH (millihenries). The core-less coil consists of several turns of heavy copper wire, and the robust construction ensures low noise and high performance. The 9220-15 application field includes AC/DC switching power supply, LED lighting, home appliance, and high-frequency transformer. Due to its excellent high-frequency characteristics, the 9220-15 can also be applied in DC/DC converters, Preamplifier circuits, and LCD TVs.

The working principle of the 9220-15 fixed inductor is based on Faraday\'s law of induction, which states that when a conductor is moving through a magnetic field, an electric current is generated along the direction of the conductor. This means the inductor is constantly transferring energy from the power source to the load. As long as the voltage stays constant, the energy flow will remain constant and the device will be able to maintain the output levels. The electromagnetic flux around the inductor produces a magnetic field which offers further resistance to changes to the current, allowing the device to remain stable in the presence of constant power.

Another important property of the fixed inductor is its core-less design. This means that the inductance of the coil is primarily determined by its number of turns as opposed to its physical size. This allows it to be used in more compact designs, making it a popular choice for modern electronics. Also, the inductor is not affected by changes in temperature, humidity, or air pressure, meaning it can be reliably used in all sorts of applications, including those with severe environment changes.

In conclusion, the 9220-15 fixed inductor is a reliable and robust electronic component for various applications. Despite its relatively small size, the inductor has excellent performance characteristics and a wide application field. It works based on Faraday\'s law of induction, and its core-less design allows it to be used in cramped spaces without sacrificing any of its high-frequency characteristics. It is reliable in all sorts of environments and can provide a constant current for a variety of circuits.
