HIGH FREQUENCY PLANAR
TRANSFORMERS
Spyglass Series (up to 140W)
Notes from Tables
1. The above transformers have been tested and approved by Pulse's IC
partners and are cited in the appropriate datasheet or evaluation board
documentation at these companies. To determine which IC and IC
companies are matched with the above transformers, please refer to
the IC cross reference on the Pulse web page. See the Spyglass
transfomer matrix on the next page for other winding configurations
that can be made available.
2. The listed transformers are designed to meet basic insulation (1.4mm
creepage and clearance with 1500Vdc isolation). Lower cost
transformers with operational insulation (1500Vdc isolation with no
creepage and clearance spacings) are available. Please contact Pulse
Power Applications Engineering for details.
3. To determine if the transformer is suitable for your application,
it is necessary to ensure that the temperature rise of the
component (ambieint plus temperature rise) does not exceed
its operating temperature. To determine the approximate temperature
rise of the transformer, refer to the graphs below.
4. Add suffix “T” to part number for Tape & Reel package (i.e. PA0168T).
5. RoHS compliant parts are being introduced. Please contact Pulse for
RoHS compliant part availability. If available, order part by adding the
suffix "NL" to the part number (i.e. PA0168 becomes PA0168NL and
PA0168T becomes PA0168NLT).
