DC Choke Reactors

MSI DC Choke Reactor
This type of inductor is used on the output of a rectifier to filter or “choke” any high frequency AC component superimposed on the DC.  The impedance of an inductor increases with frequency, allowing the low frequency DC to pass while blocking the higher frequency AC signals.


  • Copper or aluminum windings
  • Single coil or dual coil construction
  • Quiet operation
