Crossover Design Tips

  • Capacitor voltage/power ratings: Typically, 50-volt capacitors can handle up to 70 RMS Watts, 100v can handle 200w and 250v up to 500w.
      
  • Inductors gauge/power ratings: In inductors, the gauge of the wire used determines power handling.  Common values are:  20 gauge = 180 watts, 18ga = 250 to 300w, 16ga = 500w and 14ga = 800w.
