Quality
Reliability
TheMeanTimeBetweenFailure(MTBF)ofthePKJ4000E
series DC/DC converter family is calculated to be greater
than (>) 7.6 million hours at full output power and a PCB
temperatureof+110°CusingtheEricssonfailureratedata
system (TILDA/Preditool). The Ericsson failure rate data
system is based on field failure rates and is continuously
updated. The data corresponds to actual failure rates of
components used in Information Technology and Telecom
equipment in temperature controlled environments (TA=
-5...+65°C). The data is considered to have a confidence
levelof90%.FormoreinformationpleaserefertoDesign
