Fixed Inductors

A fixed inductor is an electronic device which contains components used to convert electric energy into a magnetic field. This device also has the capability to change the amplitude or phase of an AC signal. The PM20-R012M is an example of a fixed inductor.

Application Field of PM20-R012M

The PM20-R012M fixed inductor is mainly used for broadband communications such as FTTH, FTTB, and CATV systems. It has the capability to provide a flat phase and high impedance characteristics in the frequency range of 20 kHz to 3GHz. This makes it suitable for high-frequency high-return splitters, passive RF attenuators, and RF filters.

Working Principle of PM20-R012M

The working principle of the PM20-R012M involves creating a magnetic field when an alternating electric current passes through the inductor. This is done by creating an electromagnetic field which consists of a magnetic field and a electric field. The magnetic field induces a flux of electric field lines which when combined with the current creates a voltage across the winding. This voltage then induces a current in the opposite direction to the original. This is known as an alternating current, or AC, signal.

The PM20-R012M fixed inductor is designed to provide a flat phase and high impedance characteristics in the frequency range of 20kHz to 3GHz. It does this by creating a magnetic field within the device which is strong enough to induce a voltage across the winding. This voltage is then used to control the flow of the current in the opposite direction to the original. This results in a high level of impedance in the frequency range which is achieved by the strong magnetic field. The magnitude of the signal is also determined by the strength of the magnetic field.

Conclusion

The PM20-R012M fixed inductor is a versatile, high impedance device suitable for broadband communication systems. The device is able to provide a flat response and high impedance characteristics in the frequency range of 20kHz to 3GHz. This makes it extremely useful for applications such as high-frequency splitter attenuators and RF filters. The working principle of this fixed inductor involves creating a strong magnetic field which is used to induce a voltage across the winding which is then used to control the flow of current.
