Parasitics & Capacitor Selection, Part 4A: Dissipation Factor

Dissipation factor (DF) and Tan δ — that is the Q. This month, we'll look at DF and lay the groundwork for next month's blog about Q. When discussing power losses through a capacitor, DF and Tan δ are ...

Parasitics & Capacitor Selection, Part 4B: Dissipation Factor

Since capacitance bridges measure capacitance using a small AC signal voltage, it is possible to measure DF simultaneously. So, when capacitors are 100% tested, both capacitance and DF are measured at ...
