Essentially, an EMI filter is an electrical device/circuit that will help mitigate the high-frequency electromagnetic noise present on the power lines as well as on signal lines (Fig. 3). EMI filters may be classified as low pass, high pass, bandpass, or band reject.

Electromagnetic interference (EMI) is mainly defined as the unintended harmonic energy that is generated by sharp changes in circuit voltage and current (dv/dt and di/dt). Primary sources include power conversion and logic circuits. This energy can propagate into and within equipment degrading the integrity of a signal or possibly damaging components, thus affecting the equipment’s overall functionality.

An MRI FACILITY EMI FILTERS is a device that is installed at the power entry point of equipment to reduce unintended harmonic energy below circuit operational levels, as well as to meet commercial and military international EMI standards. These standards are established and regulated by the FCC, EN/CE, and various Government/Military agencies. The main frequencies of concern governing power line conducted emissions are 10KHz to 10MHz for Military environments and 150KHz to 30MHz for commercial/industrial applications. From a design perspective, EMI Power Line Filters can consist of both passive and active components. However, due to their ability to filter over a broad frequency range, passive designs utilizing inductive and capacitive elements comprise the majority of EMI filter products in the market.
