Fixed inductors, such as PM20S-180K, are passive devices that use an inductor to store energy in the form of a magnetic field. Inductors are often used in a variety of applications and serve a multitude of roles. The PM20S-180K is a type of inductor that is typically used in power supplies, high-frequency circuits, RF applications, and more. In this article, we will take a closer look at the PM20S-180K, its application field and working principle.

The PM20S-180K inductor is a surface mount device with an operating temperature range of -40°C to +85°C. It is available in a wide variety of sizes, including as small as 1.2mm x 1.2mm and as large as 3.2mm x 3.2mm. These devices are composed of an inductor core made of a ceramic material, two leads, and an optional external shield. The inductor core is composed of two concentric winding spools wrapped with copper wire. The outer spool is insulated with an insulating material. Furthermore, these inductors are capable of operating at frequencies up to 10MHz and capable of carrying currents up to 5A.

The PM20S-180K is relatively small and compact, allowing it to be used in a variety of applications. These inductors are typically used in buck, boost, and buck-boost converters because they can reduce noise and help prevent unwanted oscillations. Additionally, they can be used in noise suppression circuits. Due to their high operating frequencies and high current carrying capabilities, these inductors are also ideal for use in RF applications.

How do these inductors work? The principle behind these devices is based on Faraday\'s law of induction. This states that the induced electromotive force in an inductor is proportional to the rate of change of current. This means that when a current through an inductor is increasing or decreasing, an emf (electromotive force) is produced in the inductor due to changes in flux linked with the winding of the spool. This can be used to reduce noise or prevent unwanted oscillations.

The PM20S-180K inductor is a relatively small and versatile component that is widely used for a variety of applications. It has a maximum operating frequency of 10MHz and can carry current up to 5A. Furthermore, its small size makes it ideal for use in power supplies, high-frequency circuits, RF applications and more. This versatile device is based on Faraday\'s law of induction, which states that an EMF is produced in an inductor when the current through it is changing.
