Varistors feature increased permissible operating temperature
TDK has presented leaded EPCOS metal oxide disk varistors, which have now been approved for an increased operating temperature of 105°C (previously 85°C). The reason for this is the recertification of the B722* series of varistors 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.
The monolithic EPCOS varistors are available with rated voltages of between 11VRMS and 1,100VRMS and, depending on type, can withstand surge currents of up to 20kA (8/20µs). To assist in the design process, PSpice libraries are available here.
Main applications:
- Power supplies and converters for industrial electronics applications, as well as household appliances and telecommunication devices.
