Capacitors are used to filter out all the components of variable voltage (from frequency switching power supply reducing the impact of the current pulses) . Capacitors partially offset the sharp glitches from the relay coils .
Capacitors hutumiwa kwa chujio nje vipengele vyote ya voltage variable (kutoka frequency byte umeme kupunguza madhara ya kunde sasa) . Capacitors nusu kukabiliana glitches mkali kutoka coils relay .
