EMI/RFI filters are used to attenuate high frequency interference and protect technology-based equipment from malfunctions and hazards related to non-ideal power conditions. The PSM1-101M-02T0 is a radial lead power filter application from Murata that is designed to suppress interference and unwanted energy with a high degree of efficiency. This article will discuss the working principle and application field of the PSM1-101M-02T0.

The PSM1-101M-02T0 is a low-cost, open-frame radial lead power EMI/RFI filter with ferrite cores. The ferrite cores trap high frequency interference that enter the power line, reducing common mode and differential mode noise. The filter features two capacitors for noise suppression and two inductors for signal degradation. The capacitor-inductor combination acts as an LC network, providing excellent attenuation of unwanted signals within a given frequency range.

The PSM1-101M-02T0 filter provides low-pass filtering and is ideally suited for applications that require efficient power filtering. It is typically used in consumer electronics, telecommunications, industrial control systems, and automotive power supplies. The filter can effectively reduce power line noise, voltage sags, voltage surges, static electricity, and other interference and provides an extra layer of protection to sensitive electronic devices.

The working principle of the PSM1-101M-02T0 filter is based on the concept of series resonance. Series resonance occurs when two series-connected components have a combined reactance equal to zero. In the PSM1-101M-02T0 filter, the combined reactance of the two capacitors and the two inductors forms a parallel LC network. This LC network is tuned so that the desired frequency range is attenuated, allowing the power line to operate more efficiently.

The PSM1-101M-02T0 is a cost-effective and reliable solution for reducing power line interference. It is a popular choice for consumer electronics, telecommunications, industrial control systems, and automotive power supplies. The filter\'s LC network provides excellent attenuation of unwanted signals within the desired frequency range and helps protect sensitive electronic devices from power line noise and voltage surges.
