B722 Series Varistors

EPCOS' B722 series of varistors with increased operating temperature ratings

Image of EPCOS' B722 Series of VaristorsEPCOS' metal oxide disk varistors by TDK are approved for increased operating temperature of 105°C (previously 85°C). The B722 series of varistors have been recertified in accordance with UL 1449, 4th Edition, and IEC 61051. Raising the permissible operating temperature to 105°C also changes the climate category from 40/85/56 to 40/105/56. The flammability of the epoxy enclosure complies with UL 94 V-0.

Features Applications
  • Increased permissible operating temperature of 105°C
  • Wide range of rated voltages from 11 VRMS to 1100 VRMS
  • High surge current capability of up to 20 kA (8/20 µs)
  • Recertified in accordance with UL 1449, 4th Edition, and IEC 61051
  • Power supplies and converters for industrial electronics applications
  • Household appliances
  • Telecommunication devices
