Fixed inductors, also known as inductors, are passive components that store energy in magnetic fields. One of the most popular fixed inductors is the PD75R-393K. It is a radial leaded, 75-ohm fixed inductor, capable of withstanding up to 1.5 A of current.

The PD75R-393K is commonly used in power supply and audio applications, such as filtering and decoupling. It can be used in both DC and AC circuits, and features a wide frequency response, making it perfect for both low and high-frequency applications.

The PD75R-393K\'s working principle is fairly simple. When a voltage is applied to the winding of the inductor, a magnetic field is created around it. This magnetic field is what stores the energy. As the magnetic field builds up, it reacts with the current in the circuit and creates a back EMF (electromotive force) which opposes the supplied voltage, thus creating a resistance. This causes the current to slow down, and the magnetic field around the inductor to build up even more. This creates a self-sustaining loop, where the energy stored in the magnetic field is transferred back into the circuitry, effectively filtering it.

The PD75R-393K has many features that make it highly versatile in a wide range of applications. It has a low self-resonance frequency, allowing for superior frequency response in low-frequency applications. It has excellent inductance performance, with minimal ringing. It also features a wide operating temperature range, making it suitable for use in high-temperature applications. Additionally, its radial-leaded construction makes it easy to mount and handle, and its robust construction ensures it can withstand shocks and vibrations, making it ideal for portable and industrial designs.

The PD75R-393K is a highly versatile and reliable inductor, making it perfect for a wide range of applications, from audio to power supply. Its wide frequency response, low self-resonance frequency, excellent inductance performance, and robust construction make it particularly suitable for industrial and automotive applications.
