Fixed Inductors

Fixed inductors, also known as coils, are electronic components used to store energy and provide electromagnetic interference protection. They are commonly used in communications equipment, audio amplifiers, and various types of electrical equipment, and are an important part of most electronic circuits. A typical application of fixed inductors is the PT300-1200-VM inductor, which is a high-performance, ultra-precise inductor used in radio frequency and telecommunications systems.

Application field

The PT300-1200-VM inductor is designed for use in a variety of applications, including communications systems, digital signal processors, broadband and satellite communications systems, RF power amplifiers, and so on. It has the advantages of low DCR, wide operating temperature range, high current rating, high Q, and low insertion losses. The PT300-1200-VM is suitable for use in high-precision, low-noise circuits.

Working principle

The fixed inductor works according to the principles of Faraday\'s law of induction, which states that a constantly changing magnetic field will cause an electric current to be induced in any surrounding conductors. When the changing magnetic field passes through the inductor, it generates a magnetic field in the inductor in the opposite direction, thus storing energy and creating a back EMF. This back EMF opposes the changing magnetic field, thus reducing the amount of current that can pass through the inductor. In addition, the inductor can store energy in the form of a magnetic field, thus delaying the production of current. This means that the fixed inductor can be used to filter electromagnetic interference, by reducing any unwanted signals.

Conclusion

The PT300-1200-VM fixed inductor is a high-precision, low-noise inductor, suitable for use in a variety of applications, from radio frequency and telecommunications to power amplifiers. It is designed to work according to Faraday\'s law of induction, which states that a changing magnetic field induces electric current in surrounding conductors, storing energy and creating opposing back EMF. This allows the inductor to filter out electromagnetic interference and store energy, thus fulfilling its purpose in any circuit.
