Fixed inductors refer to inductors that cannot be adjusted or trimmed. They are often used in RF circuits, VCOs, CFOs, oscillators and other circuits that require precise characteristics. It is important that the inductance value of the inductor remain stable throughout its lifetime. The PM628S-820-RC fixed inductor is a popular choice for use in a variety of applications. This article will discuss the application field and working principle of the PM628S-820-RC.

Application Field

The PM628S-820-RC is an axial-leaded, fixed inductor with an inductance value of 820nH. This inductor is designed for use in high frequency circuits, such as RF circuits and communication equipment. This includes but is not limited to VCOs, CFOs, SMT mixers, oscillators, high frequency converters, and RF amplifiers. It is also suitable for use in current decoupling and filter circuits.

Working Principle

The PM628S-820-RC works on the principle of electromagnetism, which states that a current flowing through a wire or conductor produces a magnetic field. The inductor itself consists of a coil of wire wound around a core. This coil creates an inductance, which is the tendency of an inductor to oppose a sudden change in current flow. When current is applied to the coil, a magnetic field is created, which in turn generates an electromotive force (EMF). This EMF is known as back EMF, and is responsible for generating a counter force in the inductor which opposes the current flow. This prevents any sudden changes in the current, allowing the circuit to remain stable.

Conclusion

The PM628S-820-RC fixed inductor is a popular choice for use in RF circuits and other high frequency applications. It is suitable for use in VCOs, CFOs, SMT mixers, oscillators, high frequency converters, and RF amplifiers. The inductor works on the principle of electromagnetism, with a coil of wire wrapped around a core which creates a back EMF which opposes any sudden changes in the current. This ensures that the inductance remains stable and that the circuit remains stabilized.
