Fixed inductors are one group of electronic components whose function is to offer controlled inductance in electrical circuits. An example of a fixed inductor is the PM3316-102M. This inductor is commonly used in power supplies, line filters, and high frequency circuits.

A fixed inductor is a passive component that consists of a coil of wire wound on a core material, such as ferrite, powdered iron, copper, or air. The PM3316-102M has a ferrite core material that is wound with a copper wire. The inductance of the PM3316-102M is 102mH with an internal resistance of 0.45 Ohms. It also has a DC current rating of 2.53A and a Q factor of 50-100.

The purpose of the PM3316-102M is to reduce the amount of high frequency noise that is generated from variable voltage sources, such as the power feeds flowing into the PCB. The inductor works by creating an alternative path for the noise, which allows the power source to remain constant. This helps to reduce the chances of electrical interference and damaged components.

The PM3316-102M can be used in a variety of applications, such as AC-DC converters, switching regulators, and power supplies. When used in an AC-DC converter, the PM3316-102M can help reduce the amount of EMI (electromagnetic interference) that is generated. In a switch regulator, the PM3316-102M helps to reduce the amount of ripple and noise associated with the inputs. In power supplies, the PM3316-102M helps to filter out high frequency noise and keeps the current running through the circuit at a consistent level.

The working principle of the PM3316-102M is based on a basic law of physics, Faraday\'s law. Faraday\'s law states that an electric field produces a magnetic field, and a changing magnetic field can cause an electric field. This interaction between the electric and magnetic fields is what causes the inductor to reduce the amount of noise and ripple in a circuit.

When the PM3316-102M is placed in a circuit, the current flowing through it creates a strong magnetic field. This magnetic field creates an opposing current that opposes the original current and forces it to be uniform and consistent. This helps to reduce the noise and interference that is typically found in power sources.

The PM3316-102M is a versatile device that can be used in a variety of applications to reduce the amount of high frequency noise and interference caused by variable voltage sources. With its strong inductance and low internal resistance, the PM3316-102M is ideal for AC-DC converters, switching regulators, and power supplies.
