VDR-14D681K3.5

Component

MOVVaristorSurge protectionRadial through-hole

VDR-14D681K3.5 is a 14 mm radial MOV varistor for surge suppression, rated for 420 VAC continuous operation and 4500 A for one 8/20 µs surge pulse.

Best for

  • AC input surge suppression
  • Power-line transient protection

Avoid if

  • The application requires a clamping voltage below 1120 V at the specified test current
  • The expected surge energy or current exceeds the datasheet limits

Check before use

  • Continuous operating voltage
  • 8/20 µs surge current and 10/1000 µs energy
  • PCB lead pitch and package clearance
  • Thermal protection and temperature derating
