The MacroDensÔ 3 –7 W PKF 4000 I series true com-
ponent level on-board DC/DC power modules are
intended as distributed power sources in decentralized
– 48 V and – 60 V DC power systems. Utilization of
thick film technology and a high degree of silicon
integration has made it possible to achieve a MTBF of
more than 4.9 million hours.
The high reliability and the very low height of these
DC/DC power modules makes them particularly
suited for Information Technology and Telecom
(IT&T) applications, with board spacing down to 15
mm or 0.6 in. The over-moulded rugged design
makes them also suitable for other demanding
industrial applications. They are optimized for free
convection cooling and have an operational ambient
temperature range in compliance with present and
future application needs, including non temperature
controlled environments. The mechanical design
offers the choice of surface mount or through-hole
versions, delivered in ready-to-use tubes, trays or tape
& reel package and compatibility with semi and fully
aqueous cleaning processes.
The PKF series is manufactured using highly auto-
mated manufacturing lines with a world-class quality
commitment and a five-year warranty.
Ericsson Microelectronics AB has been an ISO 9001
certified supplier since 1991.
