BLH DC Link capacitors exceed the IEC Gold Standard for THB testing by surviving 1,500 hours at 85°C, 85% Relative Humidity with rated DC voltage applied. The industry’s toughest standard, IEC 60383 Class III-B, requires that the capacitors pass a 1,000 hour test at the same conditions. CDE’s tests also exceed the AEC-Q200 automotive humidity test which calls for 1,000 hours at 40°C, 93% RH. They are conducted with six times the moisture present in the humidity chamber compared with the AEC-Q200 tests.
