PA3288.221HL

Fixed inductors are the most commonly used type of inductors and some of the most commonly used models are the PA3288.221HL. This article will discuss the application field and working principle of these common fixed inductors.

Fixed inductors are used for many applications and are commonly found in filters, power converters, and oscillators. They are used in many electronic circuits that process and control alternating current signals. In addition to being used in electronics, they can also be found in various forms of home appliances, medical devices, and other automated systems.

The PA3288.221HL is one of the most commonly used fixed inductors. It has an inductance of 8.2 ohms and is made up of a single-layer coil. This inductor has a diameter of 12.2 millimeters and a height of 21.4 millimeters. It has an operating frequency up to 4.2MHz and a maximum current of 3A. It is made of copper-coated iron and has an external terminal configuration. It also has a maximum power rating of 75W.

The working principle of fixed inductors can be explained by their inductance. It is this inductance that governs the relationship between the voltage and current passing through a coil. When there is no voltage passing through the coil, the associated current is also zero. When a voltage is applied, the output current is proportional to the induced voltage. This means that a low-inductance coil will have a low output voltage even if a high input voltage is applied. The opposite is true for high-inductance coils.

The PA3288.221HL is a fixed inductor that is highly efficient and reliable. Its maximum current rating ensures that it can handle large load currents without overheating. Its external terminal configuration allows for easy installation and maintenance. Furthermore, its copper-coated iron construction makes it resistant to oxidation and other environmental hazards. By understanding the application field and working principle of the PA3288.221HL, you can better understand how to use this inductor in various circuits.
