Fixed inductors can be used as passive filters, chokes, impedance matching devices, and others. The LAL03VB221K is a surface-mount, molded type inductor with low DC resistance, low core loss, and wide frequency range. It is supplied in an 18-pin moulded package with a size of 0.5mm x 2mm x 1.6mm.

Application Field

The LAL03VB221K is ideal for use in a wide range of wireless communication equipment, including telephone base stations, cellular systems, mobile equipment, and other control systems. It can also be used in other audio signal applications, such as amplifier circuits and switchmode power supplies.

The LAL03VB221K is also suitable for use in TV broadcasting receivers as well as other noise suppression circuits. It can also be used in other power supplies, such as ac-dc converters and SMPS. Furthermore, it is used for differential amplifiers, as well as for high voltage and current generators.

Working Principle

The LAL03VB221K is an inductor that works on the principle of self-inductance. This means that when a current is applied to a conductor, an electromotive force (EMF) is induced, which opposes the change in current and induces self-inductance. The self-inductance of an inductor depends on the shape and size of the coil, as well as the magnetic circuit design. Because of this, different shapes and sizes of inductors will have different values of inductance.

The LAL03VB221K is an inductor with a low DC resistance and low core loss, and it operates in a wide frequency range. The lower the inductance value, the higher the current through it, and vice versa. This makes the LAL03VB221K a useful tool for controlling current in a circuit or for impedance matching. The inductor also works as an energy storage device, storing energy in its magnetic field when a current is applied.

The LAL03VB221K is an important component for specific applications in the electronics industry. It is typically used for high frequency signal filtering and impedance matching and is suitable for use in high speed circuits for improved signal integrity. It can also be used to suppress EMI/RFI interference, improve signal transmission, and reduce circuit losses.
