ADVANCE INFORMATION for pre-production products; subject to change without notice.
The device is designed to work with various kinds of capacitors such as ceramic and electrolytic capacitors. The device also requires AC mains capacitors such as a (safety-rated) class-X capacitor to be used for the cap-drop CS.
Use the minimum or better than the minimum recommended capacitor size, voltage rating, and dielectric material for all the device capacitors to ensure optimum performance. Regardless of the capacitor type selected, the effective capacitance varies with operating voltage and temperature, as a rule of thumb, expect the effective capacitance to decrease by as much as 50%.
