IntroductionFixed inductors are one type of component used in many electronic devices. The terms fixed inductor and inductor coil are often used interchangeably, but they are not the same thing. An inductor coil is a type of component used to allow electric current to flow using magnetic principles. The 9220-02 is a type of fixed inductor, which has application fields and working principles that are of interest to those designing and using modern electronic devices.Application FieldsThe application fields of the 9220-02 fixed inductor range from low-frequency filter circuits to high-power switching circuits. In low-frequency filter circuits, the 9220-02 is capable of constructing low impedances for DC and AC signals, making it great for applications that require a great deal of low-frequency signal filtering, such as communications devices, medical equipment, and power conditioning circuits. In switching circuits, the 9220-02 is used to construct high-current magnetic fields, making it great for applications that involve repetitive energizing operations. This makes it a great fit for use in motor control, switching power supply, electric vehicles, and other higher-power operations. Working PrinciplesThe 9220-02 fixed inductor works on the principles of an inductor coil, allowing electric current to flow with the help of an induced magnetic field. When electric current passes through the 9220-02 inductor coil, a strong magnetic field is formed around the coil, causing opposing voltages that push against the electric current within it. This push back of the magnetic forces against the electric current causes a slowing of the electric current, which can be used for a variety of purposes. The magnetic field also allows power to be stored within the inductor, allowing the electric current to be discharged when the magnetic field no longer keeps it contained. This makes the 9220-02 fixed inductor a great part for use in battery-operated devices as well, as it can be recharged much more quickly than a traditional battery. ConclusionThe 9220-02 fixed inductor is a great component for use in many modern electronic devices due to its range of application fields and its working principles. In low-frequency filter circuit applications, it allows high-impedance DC and AC filtering. In switching circuits, it allows for the construction of high-current magnetic fields. It also allows for a great deal of power to be stored within it, making it great for use in many battery-operated devices as well.
