Design tips

Welcome to Design Tips! In past issues, we have discussed many aspects of EMC design, including inductance. In my opinion, inductance is the second most misunderstood thing within electrical engineering, and especially EMC. (The first most misunderstood thing is `ground´). In this issue, I´ll explore the idea of inductance beyond the normal discussion of the need for a loop of current before the term `inductance´ has any meaning. The loop area is still the most important determining factor for inductance, but there is a secondary factor that is often overlooked.
