PKM 4000E PI Datasheet
Reliability
The Mean Time Between Failure (MTBF) of the PKM4000E
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 andv 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 PKM4000E Series products is:
7 .0 million hours according to DependTool .
1 .6 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 .equipment . For more

Delivery Package Information
Compatibility with RoHS requirements
Soldering Information
PKM 4000E series standard delivery packages are 100 or 20
pcs boxes (One box contains 5 or 1 full tray(s)
and 1 empty hold down tray) .
Tray Specification
Material:
Polystyrene (PS)
Max surface resistance:
10 MOhm/sq
Color:
Capacity:
20 pcs/tray
Loaded tray stacking pitch:
16 .2 mm (0 .64 In)
Weight:
133 g
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 homogeneous 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)
The PKM4000E Series DC/DC converters are intended for
through hole mounting on a PCB . When wave soldering
is used max temperature on the pins is specified to
260°C for 10 seconds . Maximum preheat rate of 4°C/s
and temperature of max 130°C is suggested . When hand
soldering, care should be taken to avoid direct contact
between the hot soldering iron tip and the pins for more
than a few seconds in order to prevent overheating .
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 .
