The new current limiter —- limiting capacitor
A few days ago, We are talking about LED indicator light, some one mentioned that capacitor limiting .i think this is good idea for reducing energy loses. it is low power that resister limiting .

In general , the indicator led of patch board adopt 1/4w 220k resister to limiting current . the electricity consumption of resister as 0.2W, it looks small. if the indicator led work long hour, for example: which also consumes 1.75 kilowatt hours a year.

in the moment, we think that implementation of capacitor to limiting current for led indicator. because the capacitor is reactive energy device in alternating current .
