Notes: 1. Inductance is measured with both primary windings connected in series (2 to 5, with 3 and 4 shorted). 2. Leakage inductance is measured on wind-
ing (2-5) with (3,4) and (7, 8, 9, 10, 11) shorted. 3.
To order RoHS compliant part, add the suffix “NL” to the part number
(i.e. PA0801 becomes PA0801 NL).

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. To determine if the transformer is suitable for your application,
it is necessary to ensure that the temperature rise of the
component (ambient plus temperature rise) does not exceed
its operating temperature. To determine the approximate
temperature rise of the transformer, refer to the graphs below.

PA08XX Transformer Winding Configuration Matrix
The following is a matrix of the winding configurations that are
possible with the Pulse PA08XX Planar Transformer Platform.
The package is typically capable of handling between 80-140W of
power depending on the application, ambient conditions and
available cooling. Once a configuration is selected, the formulae
and charts can be used to determine the approximate power
dissipation and temperature rise of the component in a given
application.
NOTES:
1. The primary inductance for any configuration can be calculated as:
Primary Inductance (µH MIN) = 2.4 * (Primary_Turns)
2
2. The above base part numbers (PA08XX) are available from stock.
3. It is possible to add a small gap to the transformer. Gapped transformers are non-standard and can be made available upon
request, but are not typically available from stock. To request a gapped version of the transformer, add a suffix 'G' to the base
number (ie: PA0801Gor PA0801.004Getc.). The nominal inductance with the a gap can be calculated as:
Primary Inductance (µH nominal) = 0.69 * (Primary Turns)
2
4. It is possible to add a primary side aux. winding to any of the above configurations as shown in the schematics. Transformers with
primary side aux. windings are non-standard and can be made available upon request, but are not typically available from stock.
The primary aux. winding can be between 2 and 16 turns. To add a primary aux. winding to a given base, use the extension .0XX.
For example, to add a 4T aux. winding to the base part number PA0801, use the part number PA0801.004. To add a 16T aux.
winding, use the part number PA0801.016.
5. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the complete part number (i.e. PA0801 becomes
PA0801Tfor no AUX - PA0801.009 becomes PA0801T.009Tfor 9T AUX). Pulse complies to industry standard tape and reel
specification EIA481.
