Hence, there is no need to use a large dc capacitor of several thousands of microfarads in sustaining a constant dc voltage, and only a small dc capacitor of several tens of microfarads is applied to act as a snubber and filter circuit.
The new Vishay Sprague SMD capacitor with capacitance values up to 2200 microfarads features a conductive polymer cathode technology that delivers low equivalent series resistance (ESR) values across a capacitance range from 47 microfarads to 2200 microfarads with a standard capacitance tolerance of plus/minus 20%.
Additional description of the Leary concept explains that the epoxy layers are "thin enough" to form a "large distributed capacitance" of at least 0.02 microfarads between the voltage plate and ground plates.
Figure 4, where epoxy layers (24), (26) are "thin enough" to establish "a large distributed capacitance" of at least 0.02 microfarads between the voltage plate (18) and ground plates (16), (20) (col.
