PSM1-471P-02T2 application field and working principle

EMI/RFI Filter application:The EMI/RFI filters are used in the systems of electronics devices, such as in computers, telecommunications systems and industrial applications, in order to reduce and/or eliminate electromagnetic interference (EMI) and radio frequency interference (RFI). These filters are generally installed at the input/output (I/O) port or line connected to the device in order to protect the electronic circuitry or components of the system from the harmful interference emanating from external sources.

The EMI/RFI filter comes in two types of designs: a resonant filter and an inductance-capacitance (LC) filter. The LC filter also includes the use of resistors. The basic design of the resonant filter is an arrangement of a single resonance network which acts as a low pass filter. This means that the filter passes the signals at low frequencies, and blocks the signals at higher frequencies, thus inhibiting the passage of EMI/RFI.

The LC filter contains two main components, namely inductors and capacitors, and two additional components, resistors. The inductors store energy in the form of magnetic fields, while the capacitors store energy in the form of electric fields. The resistors act as dampers to reduce the impedance of the LC filter, enabling it to be used in a wider range of applications.

The working principle:The working principle of an EMI/RFI filter is based on the fact that the electric and magnetic fields need to be managed in order to reduce the unwanted interference. The LC filter works by creating an electric field that interacts with the fields created by the unwanted radiation. The electric field absorbs the unwanted radiation, which is then dissipated as a form of heat, thus reducing the level of interference that is passed through the filter.

The resonant filter works by creating a resonance network which acts as a low pass filter, thus helping to eliminate the high frequency signals from passing through. This technique works by using a stepped frequency response characteristic, where the signal passes through the filter at lower frequencies, but is blocked at higher frequencies. This type of filter is ideal for systems that require both low and high frequency signals to pass through without interference.

The EMI/RFI filter is mainly used in areas that need to prevent interference from entering or leaving a system. For example, in order to ensure the reliable operation of communication systems, EMI/RFI filters are commonly employed in equipment and power lines in order to protect the system from interference. In addition, the EMI/RFI filter can also be used in order to reduce the amount of interference caused by electromagnetic radiation created by electronic components.

In conclusion, the PSM1-471P-02T2 EMI/RFI filter is widely used in a variety of applications in order to reduce or eliminate the interference caused by electromagnetic radiation. The filter works by creating an electric field that interacts with the fields created by the unwanted radiation, while the resonant filter creates a low pass filter that helps to eliminate the high frequency signals. Both of these techniques are beneficial in helping to ensure reliable operation of electronic systems and equipment, and thus are essential components for any properly designed system.
