Vishay introduces a new series of axial cemented wirewound resistors that are the industry’s first to offer a customized high voltage surge withstanding capability up to 12 kV.

  • Designed to limit in-rush currents during high voltage surges.
  • Non flammable cement coatings provide increased safety in overload conditions.
  • Maximum allowed surge handling capacity depends on the resistor model and ohmic value.

Features

  • High-voltage surge withstand capability up to 12 kV as per IEC 61000-4-5 (1.2 μs/50 μs)
  • Non-flammable cement coatings and high-grade ceramic core
  • Power rating from 1 W to 6 W at an ambient temperature of 40 ºC and 0.9 W to 5.4 W at 70 ºC
  • Resistance from 0.15 Ω to 10 kΩ – with other values available on request
  • Resistance tolerances of ± 5 % and ± 10 %
  • Temperature coefficient (TCR) of ± 200 ppm/K (± 400 ppm/K for resistance values below 1 Ω)
  • RoHS-compliant
  • Comply with Vishay Green standards

Applications

  • Power supplies
    • Electronic meters
    • industrial and home appliances
    • electronic ballasts
