Fixed inductors are special electronic components that are designed to store energy in the form of an inductor. The SDR2207-391KL is one example of such an inductor. It is a ceramic-filled, ferrite core type fixed inductor with an inductance of 220 uH and a rated current of 1.7 A.

The SDR2207-391KL is commonly used in a variety of applications such as switching power supplies, DC-DC power converters, and mains-operated power supplies. It is also used in resonant converters for air conditioning and television sets, as well as digital and analog converters used in consumer electronics systems. Additionally, it is often used as a filter inductor in frequency-doubling circuit designs.

The working principle behind the SDR2207-391KL is inductance, which is a form of energy storage. This type of inductor works by acting as a conductor when a current passes through it. When carrying a current, an inductor stores energy in the form of a magnetic field. When the current is removed, the magnetic field collapses and the energy is transferred from the inductor to the circuit.

The SDR2207-391KL is able to store more energy than a standard inductor because of its construction. It is composed of a ferrite core that is filled with a ceramic powder to give it greater inductance than a standard ferrite core. This greater inductance makes it perfect for applications where the current will be switched frequently, such as power supplies or converters.

The SDR2207-391KL is also highly flexible. Its frequency response characteristics can be adjusted by changing the core material or the shape of the magnetic field. This allows the inductor to be customized for specific applications. Additionally, the inductance of the SDR2207-391KL can be adjusted by changing the number of turns in the windings.

The SDR2207-391KL is a versatile and reliable fixed inductor that can be used in a wide variety of applications. Its ability to store more energy than a standard inductor makes it perfect for use in power supplies, converters, and frequency-doubling circuits. It is also highly adjustable, allowing it to be customized for specific applications. By understanding its working principle and applications, engineers can easily incorporate the SDR2207-391KL into their designs.
