Sponsored by ITG Electronics At higher frequencies the impedance of a common mode choke becomes an important factor to effectively suppress EMI noise. This paper will discuss common mode noise generators and how it can be suppressed by using a common mode choke; further discussing impedance improvements by using different winding techniques and wire shapes that enhance the … [Read more...]

Selecting the Proper EMI Filter Circuit For Military and Defense Applications
Introduction Insertion loss, the term used to express a filter’s ability to reduce or attenuate unwanted signals, has traditionally been measured in a 50 ohm source and 50 ohm load impedance condition, as standardized in MIL-STD-220. In this matched 50 ohm impedance condition, various types of filter circuit configurations, single capacitor, “L’s”, “PI’s”, and “T’s”, will … [Read more...]
