Fixed inductors, such as the ELJ-PA220KF2, are basic, passive electronic components consisting of a coil of wire wound around an insulated core, and they are used in many different applications within a wide range of electronics. A fixed inductor is an inductor whose inductance does not change over time or with the application of an outside source. This type of inductance is different from the variable inductors used in power supplies, in which the inductance of the device can be varied by an external control such as a dial or knob.

The ELJ-PA220KF2 is a small, shielded surface-mount power inductor with a formed copper core. It is rated for 16 Vrms and can handle currents up to 680 mA. Its SMD design makes it suitable for use in printed circuit boards, and it will fit into small spaces without issue. The inductance is 220 µH, and the component is suitable for high-frequency flyback and boost converter applications.

The working principle of the ELJ-PA220KF2 is based on the use of a magnetic field. When a current flows through the wire, an electromagnetic field is generated and stored in the coil of the inductor. This field produces an opposing electric current when other electronic components or an external force are introduced into the circuit. This opposing current is what causes the inductance to remain the same even when the external forces change, and this is the basic principle behind the use of inductors in electronics.

The ELJ-PA220KF2 fixed inductor can be found used in a wide range of applications, such as DC-to-DC converters, wireless communication systems, signal conditioning circuits, power supplies, and power converters. Inductors are essential components in power electronic systems, and the ELJ-PA220KF2 is a suitable choice for these operations. In addition, the surface-mount design of this device makes it compatible with automated soldering processes, making it easy to integrate into almost any type of circuit.

The ELJ-PA220KF2 fixed inductor is designed to be reliable and efficient, and it offers excellent performance in a number of different applications. The rated 16 Vrms and 680 mA current make it suitable for use in most electronics, and its small, surface-mount design makes it easy to install. This fixed inductor is an essential component in many electronic circuits, and its reliable operation makes it a great choice for a variety of applications.
