Characteristics

  • Fast response time
  • Low leakage current
  • Low clamping voltage
  • Almost no energy consumption in stand-by mode
  • After a surge impulse the varistors works immediately in normal mode so there is no slip current
  • Excellent absorption
  • Operating temperature: –40 °C to +85 °C for the sizes 0402 to 0805 –40 °C to +125 °C for the sizes 1206 to 2220
  • Nickel barrier

Applications

  • Protection of power supply
  • Protection of bus systems and communication lines
  • Limiting of overvoltages
  • Surge protection in accordance with EN-61000-4-5 and ESD protection in accordance with EN-61000-4-2
