Leakage Currents in the Right Perspective

featured-side
Trade-off between best attenuation effectiveness and minimum leakage current. Network filters (EMC filters) are often regarded as a Blackbox and, justifiably, the user doesn’t concern himself with its inner workings. However, for the effective use of filters, it is advantageous to have some background knowledge. The...
