Fixed inductors are basic electronic components that are designed to provide inductance in a circuit. Fixed inductors have a variety of applications, such as in power supplies, amplifiers, and capacitors. One of the most popular fixed inductors is the PM42S-181. This article will discuss the application field and working principle of the PM42S-181.

The PM42S-181 is a surface mount, low profile, wide temperature range, fixed inductor designed for use in high frequency, high current applications. It is designed to provide inductance in radio frequency circuit designs, such as ones used in satellite communications, cellular phones, and other portable communication devices. It can also be used in automotive and military applications. The PM42S-181 is also suitable for DC- DC converters, automotive inverters, switched mode power supplies, and other power applications.

The working principle of the PM42S-181 involves the ability of the device to store energy in a magnetic field. When electric current is applied to the inductor, it creates a magnetic field in the core of the inductor which then attracts and stores energy. The stored energy in the magnetic field is then released back into the circuit when the current is cycled again. The amount of stored energy is determined by the amount of current that flows through the device, and the inductance of the inductor.

The PM42S-181 is made of a low-profile magnetically shielded ferrite core and a tin-plated copper winding. The copper winding is wound around the ferrite core and the device is then plated with an anti-corrosive material. The combination of the copper winding and ferrite core provides optimal inductance with minimized losses. Additionally, the tin-plated copper winding provides good solderability and stable inductance.

The PM42S-181 fixed inductor is a versatile device that can be used in a variety of high-frequency and high-current applications. Its low profile, wide temperature range, and magnetic shielding properties make it ideal for radio frequency circuit designs. Additionally, its copper winding and ferrite core make it suitable for DC-DC converters, automotive inverters, and power supplies. By understanding the applications and working principle of the PM42S-181, designers can ensure they are selecting the right fixed inductor for their project.
