Input and Output Impedance
Both the source impedance of the power feeding and the load imped-
ance will interact with the impedance of the DC/DC power module.
It is most important to have the ratio between L and C as low as
possible, i.e. a low characteristic impedance, both at the input and
output, as the power modules have a low energy storage capability.
Use an electrolytic capacitor across the input or output if the source
or load inductance is larger than 10
H. Their equivalent series
resistance together with the capacitance acts as a lossless damping
filter. Suitable capacitor values are in the range 10–100
F.
Mounting information for PKZ 0001
The two holes on the ground pin are ovals for positioning of the pin
according to the PCB layout. The screws are delivered together with
the pin.

Reliability
Meantime between failure (MTBF) is calculated to >2.0 million hours
at full output power and a case temperature of +75°C (TA =+45°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 component
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, 6s
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
Ericsson Power Modules warrants to the original purchaser or end
user that the products conform to this Data Sheet and are free from
material and workmanship defects for a period of five (5) years from
the date of manufacture, provided the product is used within
specified conditions and not modified in any way. In case the product
is discontinued, claims will be accepted up to three (3) years from the
date of the discontinuation. For additional details on this limited
warranty we refer to Ericsson Power Modules "General Terms and
Conditions of Sales", or individual contract documents.
Limitation of Liability
Ericsson Power Modules does not make any other warranties,
expressed or implied including any warranty of merchantability
or fitness for a particular purpose (including, but not limited to,
use in life support applications, where malfunctions of product
can cause injury to a person's health or life).
