About MOVs

  • MOV - Metal Oxide Varistor-a component used to suppress voltage transients.
  • MOV is what's inside a lot of small "surge supressors" in a sturcture having a multi-grain ceramic semiconductor.
  • It has a rather high resistance until the voltage gets over a threshold, at which time the resistance drops (but not to zero).
