Picking Capacitors - Walter G. Jung and Richard Marsh

For high-current circuits, Rs can represent a significant power loss, and it is to represent losses, which can be described either by the term power factor (PF) or . The first circuit used is a simple low-pass (LP) filter, with the capacitor under test . a low DA, and the glass and mica dielectrics are good examples of this f
