High Voltage Ceramic Capacitors for Line Powered LEDs
By: Dave Johnson
line powered DC supplies for LEDs wired in long series strings use a series
connected capacitor to limit the current drawn from the power line. Typically,
these capacitors are Mylar or polyester film devices. However, I think that
much smaller ceramic type capacitors might also work. Below is a photo showing
a pair of capacitors each with the same 0.47uF 250v rating. Clearly the
ceramic device is much smaller.
