Fixed Inductors

Fixed inductors are electrical components used to store energy in an inductive circuit, modify AC waveforms, and adjust the resonance frequency of circuits. Fixed inductors are commonly used to filter noise in digital circuits, suppress differential mode commonmode interference signals, and reduce ringing in pulse circuits. The PM20-R33M fixed inductor is one such type of inductor which is designed to meet the industrial power electronics and automotive application demands.

Application Field

The PM20-R33M fixed inductor is developed with the highest rated current range and best saturation performance in the world. It is suitable for a wide range of industrial applications, including automotive, industrial power electronics, DC-DC converters, solar converters and various other applications. Primarily, they are used for high frequency noise filtering and power line electromagnetic interference suppression in digital applications, DC-DC converters, automotive alternators, and other electronics. This makes the PM20-R33M an ideal choice for motor control, automotive power electronics, lighting, and industrial power applications.

Working Principle

The PM20-R33M fixed inductor works by using electro-magnetic induction to store energy in its core. The inductor is composed of a ferromagnetic core wound by a wire coil, and when an AC current passes through the coil, it generates a magnetic flux in the core, thereby generating a magnetic field that stores energy in the inductor. This stored energy is used to create a counter voltage that weakens or reduces the amplitude of the AC waveform passing through it. The degree of counter voltage created in the inductor is determined by its inductance rating, which is how much energy the inductor can store. The PM20-R33M fixed inductor has a rated inductance of 33mH, which makes it suitable for digital circuits and other applications that require a low level of counter voltage.

The PM20-R33M fixed inductor also features a high saturation current rating of up to 20 amps, which is the highest saturation current rating of any inductor in the world. The high saturation current rating of the PM20-R33M means that it can handle high levels of electrical load without saturating or limiting the power flow, making it ideal for applications that require a relatively high amount of power.

In addition to its high saturation current rating, the PM20-R33M fixed inductor also features an excellent temperature stability rating, meaning that it can be used in high temperature environments without compromising performance. This makes it an ideal choice for applications in harsh industrial environments, such as motor control and automotive power electronics.

Finally, the PM20-R33M fixed inductor features a low stray inductance rating, which means that it minimizes the effects of other nearby inductors on its performance. This makes it an ideal choice for applications which require high levels of accuracy, such as automobile alternators and DC-DC converters.

In conclusion, the PM20-R33M fixed inductor is an ideal choice for applications requiring high levels of power and precision. It has the highest rated current range in the world, and excels in its ability to filter noise in digital circuits, suppress common mode interference, and reduce ringing in pulse circuits. It also features a high saturation current rating and excellent temperature stability, making it an ideal choice for applications in harsh industrial environments.
