EN/LZT 146 57 R1A Ericsson Microelectronics AB, March 2001
Quality
Reliability
Meantime to fail (MTTF) is calculated to >10 million hours at
full output power and a case temperature of +50°C
(TA = +40°C), using the Ericsson failure rate data system.
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
level of 90%. For more information see Design Note 002.
Quality Statement
The products are designed and manufactured in an industrial
environment where quality systems and methods like ISO 9000,
6
s and SPC, are intensively in use to boost the continuous
improvements strategy. Infant mortality or early failures in the
products are screened out by a burn-in procedure and an ATE-
based final test. Conservative design rules, design reviews and
product qualifications, plus the high competence of an engaged
work force, contribute to the high quality of our products.
Warranty
