HIGH FREQUENCY PLANAR

TRANSFORMERS

Prism Series (up to 250W)

P604.A (7/04)

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.
