PKF4910AR1A
Description
Manufacturer
Ericsson Microelectronics
Datasheet
• SMD and through-hole versions
• 78% efficiency
• 1,500 Vdc isolation voltage
• Switching frequency syncronization
• MTTF >10 million hours at +50°C case
• Low EMI
The MacroDens™ 9.9W PKF 4910A I true
component level on-board DC/DC power modules are
intended as distributed power sources in decentralized
– 48 and – 60V DC power systems. They are optimized
for an operational ambient temperature range in
compliance with present and future application needs,
including non temperature controlled environments.

8.0 mm (0.315 in.)
temperature
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.
