Notes
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.
