Reliability
According to MIL-HDBK-217F the calculated MTBF
value at 100% load (from PKV 5211 PI) at the following
ambient temperatures will be approx.:
Tamb Hours
0 °C
2.7 million
10 °C
1.5 million
25 °C
650 000
40 °C
276 000
60 °C
88 000
75 °C
37 000
At 80–100% load the case temperature will be approx.
15–20 °C higher than the ambient temperature.

Miscellaneous
The PKV Series DC/DC Converters are intended for through
hole mounting in a PCB. When wave soldering is used, the
temperature on the pins is specified to maximum 260 °C
for maximum 10 seconds. Maximum preheat rate of 4 °C/s
and temperature of max 150 °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.
A no-clean (NC) 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.
Soldering Information
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 homoge-
neous 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)
When powering loads with significant dynamic current
requirements, the voltage regulation at the point of load
can be improved by addition of decoupling capacitors at
the load. The most effective technique is to locate low ESR
ceramic and electrolytic capacitors as close to the load
as possible, using several parallel capacitors to lower the
effective ESR. The ceramic capacitors will handle high-
frequency dynamic load changes while the electrolytic
capacitors are used to handle low frequency dynamic
load changes. Ceramic capacitors will also reduce any
high frequency noise at the load. It is equally important to
use low resistance and low inductance PCB layouts and
cabling.
External decoupling capacitors will become part of the
control loop of the DC/DC converter and may affect the
stability margins. As a “rule of thumb”, 100 F/A of output
current can be added without any additional analysis. The
ESR of the capacitors is a very important parameter. Power
Modules guarantee stable operation with a verified ESR
value of >10W across the output connections.
