Fixed inductors are self-contained electronic devices, typically in the form of a coil of insulated wire wrapped around a magnetic core, that provide a precise amount of inductance.PA3199.321HL is a fixed inductor that can be used for many different applications.

Application Fields

PA3199.321HL is a low-profile, high frequency inductor with an inductance of 2.2uH and a current rating of 1A. These characteristics make it suitable for low frequency power supply designs, as well as high frequency switching regulator and DC-DC converter applications. It can also be used in conjunction with transformers for applications such as RF filters and EMI shielding.

Additionally, the PA3199.321HL is also suitable for use as a balun in balanced transformers, and as an output filter for various switching controllers. It can also be used in applications such as RF amplifiers, clock oscillators and charge pumps.

Because of its low profile design, the PA3199.321HL can be used in designs where board space is limited. Its leads can be easily soldered to a PCB, and its small size allows for better heat dissipation and a long life.

Working Principle

Fixed inductors are widely used in electronic circuits because of their unique function – storing and releasing energy in the form of an electromagnetic field. This field is generated when an alternating current (AC) flows through the inductor\'s winding, creating a surrounding magnetic field. This field then interacts with the current, resisting changes in current flow.

The magnitude of this resistance, known as inductance, is determined by the number of turns in the inductor\'s winding, the core material, and the overall size of the coil. The higher the inductance, the more energy is stored in the magnetic field.

The PA3199.321HL is a high frequency inductor, meaning it is specially designed to work with high frequency AC signals, such as those found in radio frequency (RF) applications. This means that it can store higher amounts of energy than a lower frequency inductor.

When used in a circuit, the PA3199.321HL provides a fixed amount of inductance that does not change, regardless of the frequency of the signal. This makes it ideal for use in an RF circuit, where the signal frequency must remain constant.

Fixed inductors have many applications in electronics, and the PA3199.321HL is one such component. Its low profile design, high frequency properties, and fixed inductance make it suitable for many different applications, from low frequency power supplies to RF amplifiers.
