MOVVaristor20D20 VACThrough-holeSurge protection

VDR-20D330K is a radial disk MOV rated for 20 VAC or 26 VDC continuous operation, with 29.7-36.3 V varistor voltage and 65 V maximum clamping voltage.

Best for

  • Transient protection on low-voltage power lines
  • Through-hole surge suppression designs

Avoid if

  • The continuous voltage exceeds 20 VAC or 26 VDC
  • The application produces repeated heat or surge energy above the rated limits

Check before use

  • Maximum clamping voltage at the actual surge current
  • Surge waveform, pulse count, and energy
  • Thermal derating above 125°C
