EMI/RFI Filters (LC, RC Networks) are filters that are engineered to reduce the risk of Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). Filters typically consist of two or more networks, such as LC, RC, and CC networks, and are designed to suppress unwanted signals from existing electronic circuits and devices. The PSM1-101M-10T2 is one such EMI/RFI filter, developed by Molex for use in applications such as medical devices, automotive electronics, office machines, communication systems, and industrial devices. This particular filter is capable of passing up to 10 amps of current and operates between 10kHz and 1GHz. This article will discuss the application field and working principle of the PSM1-101M-10T2 EMI/RFI filter.

Application Field :

The PSM1-101M-10T2 EMI/RFI filter can be used in numerous industrial and consumer applications that require the reduction or elimination of electromagnetic interference and radio frequency interference. Its compact size and light weight make it ideal for applications where space and weight are factors such as automotive applications. In medical applications, the filter is used to reduce interference caused by X-rays, ultrasound, and other medical equipment. It is also used in office machines, communication systems, and industrial equipment.

Working Principle :

The working principle of the PSM1-101M-10T2 EMI/RFI filter is based on the concept of impedance matching. Impedance matching is the process by which the output of one device is made to match the input of another device, so that maximum signal transfer can be achieved. When an LC or RC network is placed between two circuits, it creates an impedance mismatch that reduces the amount of interference that can reach the receiving circuit. This type of filter is also designed to pass signals within its frequency range while attenuating signals above or below that range. This ensures that only the desired signals are allowed to pass through the filter.

In addition to providing impedance matching, the PSM1-101M-10T2 filter also employs capacitors, inductors, and resistors in order to attenuate signals outside its operational frequency range. When a signal is introduced to the filter, the capacitors and inductors allow desired signals to pass frequencies while blocking signals outside of their bandwidth, while the resistors dissipate the energy of any unwanted signals.

In summary, the PSM1-101M-10T2 EMI/RFI filter is designed for applications that require the reduction or elimination of electromagnetic interference and radio frequency interference. Its working principle is based on the concept of impedance matching in order to provide the desired level of signal attenuation and rejection. The filter utilizes capacitors, inductors, and resistors to block signals outside of its operational frequency range in order to ensure that only the desired signals are allowed to pass through the filter.
