An inductor is a passive electrical component that stores energy in its magnetic field. Fixed inductors are self-contained components, not susceptible to external forces. The most common type is the PM1008-3R3K-RC, an axial leaded fixed inductor with a cobbled winding that is suitable for both high- and low-frequency use.

The PM1008-3R3K-RC is a ceramic core inductor with a rated current of 3A and an inductance of 3.3μH. Its total wire length is 1 mm, its wire diameter is 0.2 mm, and it has a maximum sustained current of 4A. It is a polarity sensitive component, meaning it must be correctly oriented in the circuit for proper operation.

The PM1008-3R3K-RC is mainly used in power supplies, audio amplifiers, and radio-frequency (RF) circuits. It is often used in power supply circuits to reduce ripple noise, audio circuits to improve sound quality, and in RF circuits such as filters for oscillators and amplifiers.

The working principle of the PM1008-3R3K-RC is based on the law of induction, which states that a current flowing through a wire creates a circular magnetic field around the wire. When an alternating current (AC) is passed through the PM1008-3R3K-RC, it creates a changing magnetic field, which induces a voltage across the inductor’s windings, which is equal and opposite to the applied voltage. This voltage opposes the applied voltage and is responsible for the inductor’s inductive reactance.

The PM1008-3R3K-RC is capable of a wide range of inductances, and this makes it suitable for a variety of purposes. The inductor’s inductive reactance limits the current in the circuit, and this can be used to regulate the power supply, reduce ripple noise, or create filters for AC signals. The inductor’s value can also be changed by adding or removing turns of wire, which is possible because of the cobbled winding.

The PM1008-3R3K-RC is a low cost, efficient, and reliable fixed inductor that is used in many applications. Its small size and high efficiency make it an attractive option for many different circuit types. The PM1008-3R3K-RC is an excellent choice when a small footprint and high-frequency performance are desired.
