Fixed inductors are electronic components whose inductance value doesn’t change with a change in current. They are primarily used to filter or trap rf signals, filter out noise, regulate voltage stability to minimize rf interference, and provide support to device timing in certain circuits. Fixed inductors come in a wide range of sizes, shapes, and tolerance levels, from tiny chip inductors with near-zero tolerances to large coil inductors.

The LQH6PPN220M43L is a fixed inductor designed by Murata. This component is an SMD ferrit core type power inductor with a rated current of 4.3A. The inductance is fixed at 22uH +/- 20% with a DC resistance of 0.082ohm. It is designed for use in a wide variety of applications, such as DC-DC switching power supplies, parallel circuits, and EMI filters.

The working principle of the LQH6PPN220M43L is simple. When a current passes through the inductor, a magnetic field is generated around the inductor. The magnetic field increases proportionally with the current and as a result, a voltage is induced in the inductor in the form of counter electromotive force. This phenomenon is known as inductance. This counter electromotive force opposes the original current, causing the current to slow down as it passes through the inductor.

The LQH6PPN220M43L is well-suited for high-current circuits which require a high degree of noise suppression. Its high inductance value makes it ideal for circuits operating at high frequencies and with high-current loads. The low DC resistance also helps reduce ripple voltage and minimize power loss. The component is also widely used in DC-DC switching power supplies, for filtering, and in devices with stability requirements.

In short, the LQH6PPN220M43L is a fixed inductor used for a variety of applications such as noise suppression, filtering, and voltage stabilization. Its working principle is based on the principle of inductance, where a current passing through the inductor induces a voltage in the form of counter electromotive force. This component is well-suited for high-current circuits with noise suppression requirements and is widely used in DC-DC switching power supplies, for filtering, and in devices with stability requirements.
