Contributing Factors of EMI Filter Performance Passive electrical filter design consists of inductors and capacitors in various configurations, and possibly using resistors to discharge capacitors or dampen circuit resonance. In an ideal world, inductors increase impedance with higher frequency, and capacitors decrease impedance with higher frequency, while resistor values do not change. However, this is not the case in real applications. The limiting factors of real-world components has to be understood to recognize the limitations...

Medical Versus Regular EMI Filters damage sensitive equipment. However, although EMI filtering is in wide use, it isn 't uniform in structure or application. What might serve in one industry won 't necessarily in another. For example, the medical industry and equipment require approaches that can support and satisfy the literal life-or-death nature of the applications. From sensitive measurements of physiological phenomena such as EKGs and EEGs, to accurate delivery of medicines, including equipment like X-rays and MRIs that use...
