Varistors

MOVVaristorZnORadialThrough-holeTransient protection

VDR-20D180L is a radial 20 mm ZnO MOV for low-voltage transient suppression, rated at 11 VAC / 14 VDC continuous voltage.

Best for

  • Low-voltage AC or DC transient suppression
  • Radial through-hole protection circuits

Avoid if

  • The steady-state voltage exceeds the specified continuous-voltage rating
  • The application requires a documented lifecycle or availability commitment

Check before use

  • Actual operating voltage and tolerance
  • Surge current, energy and repetition rate
  • PCB lead spacing and available clearance
