Fixed inductors, also known as chokes, are electronic components that store energy in the form of electric or magnetic fields. The purpose of a fixed inductor is to block or resist alternating electric currents, allowing only DC current to flow in certain directions. In this context, PD75R-473K is an example of a fixed inductor.

The PD75R-473K fixed inductor is a low-inductance, non-polarized device designed for AC line-filtering applications in computers, monitors, and other systems that require high-frequency filtering. It is a surface-mount device (SMD) with three pins, and the inductance of the device is rated at 75 mH at 1 kHz. The operating frequency of the device is from DC up to 1 MHz. It has a maximum DC current rating of 33 mA and a maximum operating temperature of 125 °C.

The PD75R-473K operates on the principle of inductance. When a current passes through an inductor, it creates a magnetic flux. This flux can then be used to store energy in the form of a magnetic field. When this flux is disrupted, the energy stored in the magnetic field is released and this is what produces the current that is known as inductance.

The use of this device is to reduce noise and interference generated from unwanted signals caused by AC line-filtering in PCs, monitors, and other systems. It helps reduce the noise generated by high-frequency switching devices and also reduces the radiated emissions from these devices. It can also reduce crosstalk and transmission loss caused by capacitive line noise. This makes it an effective tool in improving power efficiency in electronics.

The applications of the PD75R-473K fixed inductor include power supply filtering, switching power supply circuits, audio amplifiers, AC to DC converters, and signal line filtering. This device is also frequently used in power supply noise suppression, power line interference rejection, and surge protection in computer systems, home entertainment systems, and other sensitive electronic devices.

In summary, the PD75R-473K is a very useful fixed inductor component that is designed specifically for AC line-filtering applications. Its low-inductance rating, wide operating frequency range, and high-temperature rating make it suitable for a variety of applications. Its ability to reduce noise and interference makes it an important component in ensuring power efficiency in computers and other electronic devices.
