PKJ 4216N PIT Datasheet
Reliability
The PKJ 4216N PIT DC/DC converters are intended for
through hole mounting on a PCB. When wave soldering is
used max temperature on the pins are specied 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 ux is recommended to avoid entrapment of
cleaning uids in cavities inside of the DC/DC power module.
The residues may affect long time reliability and isolation
voltage.

Design for Environment (DfE)
The PKJ 4216N PIT DC/DC converters are designed to full
the wanted functionality with minimum environmental impact.
The PKJ 4216N PIT DC/DC converters are RoHS complaint,
meaning that the content of hazardous substances are below
the following levels:
Lead (Pb):
1000 ppm by weight
Mercury (Hg):
1000 ppm by weight
Cadmium (Cd):
100 ppm by weight
Hexa Valent Chromium (Cr6+):
1000 ppm by weight
PBB & PBDE:
1000 ppm by weight
The low weight high efciency converters are shipped in a
recyclable package.
The Mean Time Between Failure (MTBF) of the PKJ 4216N
PIT series DC/DC converter is calculated at full output power
and an operating ambient temperature (TA) of +40°C. Different
methods could be used to calculate the predicted MTBF and
failure rate which may give different results. Ericsson Power
Modules currently uses two different methods, Ericsson
failure rate data system DependTool and Telcordia SR332.
Predicted MTBF for the PKJ 4216N PIT products is:
3 million hours according to DependTool.
1.9 million hours according to Telcordia SR332, issue 1,
Black box techique.
The Ericsson failure rate data system is based on field
tracking data. The data corresponds to actual failure rates
of components used in Information Technology and Telecom
(IT&T) equipment in temperature controlled environments (TA
= -5...+65°C). Telcordia SR332 is a commonly used standard
method intended for reliability calculations in IT&T equipment.
The parts count procedure used in this method was originally
modeled on the methods from MIL-HDBK-217F, Reliability
Predictions of Electronic Equipment. It assumes that no
reliability data is available on the actual units and devices for
which the predictions are to be made, i.e. all predictions are
based on generic reliability parameters.
