HIGH FREQUENCY PLANAR
TRANSFORMERS
Prism Series (up to 250W)
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. Other winding configurations are available.
Please contact Pulse Power Applications Engineering for more
information.
2. 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 tem-
perature rise of the transformer, refer to the graphs below.
