Fixed inductors are electrical components that are designed to produce inductance, the property of a circuit to resist changes in current producing a corresponding voltage. In their most basic form, they consist of a simple coil of material placed around a ferrous nucleus. Different types of inductors are available based on techniques used to produce them and their specific design. One type of such inductor is PM3316S-3R3M-RC.

The PM3316S-3R3M-RC is a surface mount inductor made with a ferrite core. It features a low resistance of 1.24 ohms with a rated current of 0.50A. It is housed in a compact package and is made with a copper-clad aluminium base material. Its inductance is 3.3uH and tolerance is ±20%. PM3316S-3R3M-RC has a self-shielded construction and is ideal for high frequency applications. It is RoHS compliant and offers good thermal performance.

Applications of PM3316S-3R3M-RC include but not limited to DC-DC converters, switching power supplies, LED drivers, power supplies, DC filtering circuits, and communication products. It can be used for high frequency switching circuits like power inverters and controllers. It is also used as an emitter follower for pre-medical linear operations.

The working principle of the PM3316S-3R3M-RC is the same as for any other inductor. Whenever a current flows through the inductor it produces a magnetic field. This magnetic field in turn induces back EMF (electromotive force) in the coil. As the current increases the magnetic field become stronger and the back EMF also increases in turn. This back EMF opposes the applied voltage and acts to reduce the current.

The magnetic field is sustained in the coil for as long as the current is applied across the inductor. The magnitude of the back EMF is dependent on the current applied and the inductance of the coil. The inductance of a coil is determined by the number of turns of the winding, the material used for the core, and the geometric shape of the inductor.

The PM3316S-3R3M-RC inductor features a low resistance and high inductance ratio. This allows it to be used in a wide variety of applications requiring high frequency and low-resistance inductors. The compact design of the inductor also makes it perfect for incorporation into small form-factor applications. The self-shielded design ensures that the inductor will not emit any unwanted EMI. In addition, the inductor is RoHS compliant, making it very attractive for use in a wide range of consumer and industrial applications.
