Fixed Inductors: PM42S-120 Application Field and Working Principle

Inductors are used for a variety of applications, from providing electrical energy storage and signal shaping to filtering and coupling. The Fixed Inductor PM42S-120 is a popular breed of inductor, as its small form factor and high inductance make it suitable for a range of applications. In this article, we will take a look at the application field and working principle of PM42S-120 and discuss how it can be best utilized for accurate performance.

What is Fixed Inductor PM42S-120?

The Fixed Inductor PM42S-120 is a surface mount choke coil whose primary purpose is to prevent the flow of alternating current to a single direction. It measures just 2.55mm x 2.55mm with an inductance value of 120uH ± 20%, allowing it to be easily incorporated in projects and circuits with limited space. In addition, its high frequency range of 0.1MHz to 1GHz makes it well suited for a range of applications.

Application Field of PM42S-120

The PM42S-120 is used in a wide variety of applications. It is commonly used in converter circuits like switch mode power supplies, providing isolation between input and output terminals as well as locking the current. Its performance in filter circuits is also notable, as it can be effectively used to reduce noise in high frequency applications. The PM42S-120 is also commonly used in oscillator circuits for supplying current in required active circuits, as well as in RF systems to reduce signal interference.

Working Principle of PM42S-120

The working principle of the PM42S-120 is based on Lenz’s law. Lenz’s law states that an induced current is produced in a conductor when it is exposed to a changing magnetic field. The PM42S-120 is an inductor, and it uses this principle to prevent the flow of current in one direction.When an alternating current is applied to the PM42S-120, a magnetic field is created around the inductor. This magnetic field causes an electric field to be generated in the opposite direction of the applied current, blocking the current in a single direction and ensuring that it can’t escape in the other direction. This helps to prevent current surge and makes power conversion more efficient.

Conclusion

The PM42S-120 is a versatile fixed inductor that has a wide range of applications due to its small form factor and high inductance value. Its ability to block alternating current in one direction makes it a popular choice for circuits, and its simple working principle based on Lenz’s law is easy to understand. In conclusion, the PM42S-120 is a useful inductor component that can be utilized to rapidly boost the efficiency of complex circuits.
