The electrical industry is continuously evolving due to the advanced technology and development of several electronic devices. Fixed inductors are one such component. As the name implies, the inductors used in these devices are fixed, meaning they do not move mechanically. In most cases, these components are also referred to as chokes or coils. They are composed of an inductive coil and a ferromagnetic core, with the help of which they are able to store energy. The PM1608S-472M is an example of a fixed inductor.PM1608S-472M is a surface mounted fixed inductor which measures 12.3 mm x 8.2 mm in size. It is manufactured by Walsin Technology Corp, and features an inductance of 470uH. This inductor has a rated current of 450mA, and can operate within a temperature range of -40⁰C to 85⁰C.Fixed inductors such as the PM1608S-472M have a wide range of applications. They are used mainly in DC/DC converters, inverters, switching power supplies, solid-state switches, motor control circuits, signal circuits, coupling circuits and medical circles. They are also used extensively in the consumer electronics industry, such as in laptops, cell phones, MP3 players and other portable electronics.The working principle behind the PM1608S-472M is the development of a magnetic field when a current passes through an inductive coil. This process is known as the generation of mutual inductance. This mutual inductance which is created in the component results in the development of a flux density which is bounded by the inductance limitations of the coil material. Under the presence of an increasing flux density, the coils will reach their magnetic saturation and thus generate a unidirectional current in the coil. This current flow will become the current source to the circuit, preventing any disturbances or step changes from other external sources.In conclusion, the PM1608S-472M is a surface mounted fixed inductor which is widely used in various electronic circuits. The component consists of an inductive coil along with a ferromagnetic core, which helps it in storing energy. It is mainly used in DC/DC converters, inverters, switching power supplies, solid-state switches and signal circuits. The working principle of the component lies in the generation of mutual inductance which results in the development of a unidirectional current in the component.
