Quality
Reliability
The Mean Time Between Failure (MTBF) of the PKJ 4000E
series DC/DC converter family is calculated to be greater than (>)
7.6 million hours at full output power and a PCB temperature
of +110°C using the Ericsson failure rate data 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 level of 90%. For more information please refer to
Design Note 002.
Quality Statement
The PKJ 4000E series DC/DC converters are designed and
manufactured in an industrial environment where quality
systems and methods like ISO 9000, 6σ (sigma), and SPC
are intensively in use to boost the continuous improvements
strategy. Infant mortality or early failures in the products
are screened out and they are subjected to 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
Warranty period and conditions are defined in Ericsson Power
Modules General Terms and Conditions of Sale.

Miscellaneous
The PKJ 4000E Series DC/DC converters are intended for
through hole mounting on a PCB. When wave soldering is
used max temperature on the pins are specified to 215°C for 10
seconds. Maximum preheat rate of 4°C/s is suggested. When
hand soldering is used a thermocouple needs to be mounted on
the DC/DC converter pins to verify that pin temperatures does
not exceed 215°C for longer time than 10 seconds with the used
soldering tools.
No-clean flux is recommended to avoid entrapment of cleaning
fluids in cavities inside of the DC/DC power module. The
residues may affect long time reliability and isolation voltage.
Compatibility with RoHS requirements
The products are compatible with the relevant clauses and
requirements of the RoHS directive 2002/95/EC and have a
maximum concentration value of 0.1% by weight in homogene-
ous materials for lead, mercury, hexavalent chromium, PBB and
PBDE and of 0.01% by weight in homogeneous materials for
cadmium.
Exemptions in the RoHS directive utilized in Ericsson Power
Modules products include:
- Lead in high melting temperature type solder (used to
solder the die in semiconductor packages)
- Lead in glass of electronics components and in electronic
ceramic parts (e.g. fill material in chip resistors)
- Lead as an alloying element in copper alloy containing up to
4% lead by weight (used in connection pins made of Brass)
