Notes
1. The purpose of the T609 data sheet is to serve as a
selection guide for Pulse products matched to
Siemens telecom transceiver chips. For complete
electrical, mechanical and safety information, request
the data sheet listed next to the part number. The data
sheets can be requested through any Pulse location
worldwide, authorized distributors, the WEB site or
through the “Quick-Facts” system. Please see the
back page for more information.
2. In this catalog, turns ratio is expressed as
“primary:secondary”. The term “CT” designates a cen-
ter tapped winding. The term “CS” designates a split
center tap winding. A center tapped winding can be
created by connecting two ends of a split center wind-
ing together on the printed circuit board. In ISDN S
applications, the primary winding is the line side trans-
former winding.
3. Standard packaging for the chokes and transformers
listed in this catalog is anti-static tubes. Optional anti-
static tray packaging can be ordered for the surface
mount SC and LA packages by adding an “R” suffix to
the part number, (ie: PE-65795R). Optional tape and
reel packaging can be ordered for surface mount
packages by adding a “T” suffix to the part number,
(ie: PE-65795T). See Table A for more information.
