Component

MOVvaristor14 VAC18 VDC43 V clamp7.5 mm pitchRoHS

VDR-14D220K is a radial zinc-oxide MOV intended for low-voltage surge suppression. It supports 14 VAC or 18 VDC continuous operation and clamps to 43 V maximum at a 10 A 8/20 µs surge.

Best for

  • Low-voltage DC rails up to 18 VDC
  • Low-voltage AC circuits up to 14 VAC
  • Transient suppression with 7.5 mm lead spacing

Avoid if

  • Continuous voltage exceeds 14 VAC or 18 VDC
  • Required surge energy or pulse repetition exceeds the datasheet ratings
  • A tightly controlled clamp voltage below 43 V at 10 A is required

Check before use

  • Continuous AC/DC voltage and tolerances
  • Surge waveform, peak current, energy, and repetition rate
  • Fuse coordination and safe failure requirements
  • Radial mounting clearance and 7.5 mm lead spacing
