Fixed inductors are electronic components that store energy in a magnetic field when the component is energized by an electric current. The 4445R-17J is a common type of fixed inductor. It is an AC/DC fixed inductor, with an inductance rating of 0.4 uH. The 4445R-17J is commonly used in applications such as RF signal filtering, power supply filtering, and switching power supply circuits. It has a maximum operating temperature of 85 degrees Celsius and a rated insulation voltage of 200VAC.

Application Field

The 4445R-17J is most commonly used in RF signal filtering, power supply filtering, and switching power supply circuits. It is also used in audio frequency circuits and in digital circuits. It is also used in motor control applications, such as electric power steering systems.

Working Principle

The 4445R-17J is a fixed inductor. It works by storing energy in a magnetic field when current flows through it. This magnetic field dissipates when the current stops flowing. This creates a "fly-back" effect that reduces the amplitude of the AC voltage passing through the inductor. This preserves the sine wave shape of an AC signal, and helps to regulate the current. In power supply applications, this helps to ensure correct and stable voltage levels.

The 4445R-17J also acts as a filter in audio frequency circuits, reducing spurious signals and noise. In digital circuits, it helps to prevent interference between different signals. When used in motor control applications, it helps to regulate the current in the circuit, ensuring that there is not too much or too little current flowing.

The 4445R-17J is a common and reliable type of fixed inductor, and it is used in a variety of different applications. It is capable of handling a wide range of voltages and currents, and it is designed to operate reliably in environments with temperatures up to 85 degrees Celsius. It is a popular choice for many different types of electronic circuits.
