Fixed inductors are electrical components in which the inductance value of a coil remains constant regardless of changes in current, frequency, or temperature. They are used in all types of electronic circuits, from high power transmitters to low-noise digital receivers, and have a variety of applications. The SDR2207-470K is one example of a fixed inductor which is commonly used in modern circuit designs.

The SDR2207-470K is an axial leaded inductor with a high-quality ferrite core and an aluminized steel base. It has an inductance of 470µH (microhenry), and a resistance of 500 mΩ max (milliohms). The device has a current rating of 2.3A and an operating temperature range of -40°C to +85°C. It is capable of withstanding a voltage of up to 40V.

The SDR2207-470K has an axial construction which allows it to fit neatly into any circuit without needing extra space. The ferrite core helps to produce a higher value of inductance. The aluminized steel base supports the core and provides a good electrical pathway. The SDR2207-470K has a good frequency response, making it suitable for high-frequency applications. It also has a very low profile and is small enough to be integrated into more complex circuits with minimal effort.

The primary application of the SDR2207-470K is in DC/DC converters, which are used to convert the input voltage of a power source to a lower voltage that can be used by a device. The inductor helps to stabilize the circuit and reduce output voltage ripple. It can also be used as a filter, as it can block the passage of high-frequency signals while allowing the lower-frequency signals to pass. It is also used in switch mode power supplies, where it helps to provide a smooth flow of current, reducing the amount of heat dissipated and increasing the efficiency of the circuit.

The working principle of the SDR2207-470K is based on Faraday’s law of induction. When a current is passed through the inductor, a magnetic field is created that opposes the current flowing through it. This produces a voltage across the inductor which is proportional to the rate of change of current. The inductor helps to limit the rate of change in the current, thus producing a filter effect. The inductor also helps to reduce output ripple and stabilize the circuit.

In conclusion, the SDR2207-470K is an axial leaded fixed inductor with a ferrite core and aluminized steel base. It has a high-quality inductance of 470µH, a resistance of 500 mΩ max, and a current rating of 2.3A. Its primary application is in DC/DC converters and switch mode power supplies, but it can also be used as a filter. The working principle of the SDR2207-470K is based on Faraday’s law of induction, which enables the inductor to reduce output ripple and stabilize the circuit.
