Fixed Inductors

Fixed inductors are two-terminal passive components. They are commonly used in applications where storing and releasing energy is important, such as filtering, time delays, matching impedance, and signal processing. Fixed inductors take a variety of shapes and sizes depending on their application, but their basic components are the same.

The P3519-222K fixed inductor is a small size, low-profile, surface-mount device. It consists of a magnetic core, a coil winding, and a plastic external enclosure. The core is made of a ferromagnetic material, such as ferrite or iron. The coil winding is what produces the magnetic field and is composed of many insulated copper wires wound around the core in a regular pattern. The plastic external enclosure around the core and winding provides mechanical protection and insulation.

Application Field and Working Principle

The P3519-222K fixed inductor is mainly used in switching power supplies, mobile communication applications, and other consumer electronics. It performs the same basic function as any other fixed inductor — capturing and storing energy in its coil winding. When an electrical current passes through the coil winding, a magnetic field is created which stores the energy. When the current is reduced or removed, the magnetic field collapses and the stored energy is released.

This inductor can also be used to provide a source of harmonic and reactive power, which is important for a variety of consumer electronics applications. This type of inductor is also desirable for applications requiring a low-profile device, such as those used in smartphones. Due to its small size and low profile, the P3519-222K fixed inductor is ideal for use in high-density printed circuit boards.

The P3519-222K fixed inductor has a Z (inductance) value of 22uH and can handle currents up to 4.8A and voltages up to 9.0V. It also has a high Q (quality factor) and a DC resistance of 0.78ohm. Its size measures only 8.0mmx8.0mmx2.5mm, so it is highly recommended for applications in which the usage of space is a key factor.

In conclusion, the P3519-222K fixed inductor is a reliable and small size device that can be used in a wide range of applications. It is highly versatile and can handle large currents and voltages, as well as provide a source of harmonic and reactive power. Its small size and low profile make it an ideal choice for applications that require minimal use of space.
