Design Kit WE-VD Disk Varistors

Order Code 820999

Characteristics

  • Fast response time
  • Low leakage current
  • Low clamping voltage
  • Wide range of voltages available
  • Almost no energy consumption in stand-by mode
  • After a surge impulse the varistor works immediately in normal mode so there is no slip current
  • Excellent absorption at surge impulses
  • Operating temperature:–40 ºC to +85 ºC for types up to 95 VRMS–40 ºC to +125 ºC for types from 115 VRMS
  • Response time < 25 ns
  • UL1449 3rd File E332875
  • 14mm HighSurge and all 20mm Types greater or equal to 50Vrms are certified for use in Type 2 SPD applications (a few parts are still in progress)
  • CSA File 224856
  • VDE File 40016986 and 40016998 incl. IEC60950-1 Annex Q

Applications

  • 12–48 VDC distribution
  • 110–400 V power supply
  • Leakage of voltage peaks
  • Surge protection in accordance with EN 61000-4-5
