Additionally, the LAL02VA221K features a gold-plated terminal contact including an integrated insulator.

Applications

Due to its well-rounded specifications, the LAL02VA221K can be used in a variety of power and signal conditioning applications. Some of the common usages include: DC to DC converters, voltage regulators, antenna switch circuits, and high-frequency filtering. In particular, the LAL02VA221K is highly suited for intermediate voltage AC/DC conversion, and applications that require choke choke-filter performance. Furthermore, the LAL02VA221K can be used in audio circuits and Power Over Ethernet (PoE) systems, as well as automotive audio systems.

Working Principle

The working principle of a fixed-inductor is fairly simple. When a current passes through the device, a magnetic field is created around the core, causing a voltage drop across the device. This voltage drop is proportional to the inductance value and current of the device. The greater the inductance, the greater the voltage drop. Therefore, the LAL02VA221K can be used to regulate or reduce the magnitude of the current passing through it. Additionally, the inductance value can be adjusted by changing the length of the wire winding, and the current limit can be adjusted by adding a core of magnetic material to the coil.

Conclusion

The LAL02VA221K is a very reliable and versatile fixed-inductor, designed for applications that require low-power inductance combined with superior performance. It is a great choice for applications such as DC to DC converters, voltage regulators, audio circuits, and automotive audio systems. Furthermore, its working principle is fairly simple, relying on a magnetic field being formed around the core, which results in a voltage drop when a current passes through it. With these properties, the LAL02VA221K is an ideal choice for a variety of power and signal conditioning applications.
