The package is typically capable of handling between 150-250W 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.

The primary inductance for any configuration can be calculated as: non-standard and can be made available upon request, but are not typically available from Primary Inductance (µH MIN) = 3.4 * (Primary_Turns) 2 stock. To request a gapped version of the transformer, add a suffix “G” to the base number 2. The above base part numbers (PA09XXNL) are available from stock. (i.e. PA0901NLG). The nominal inductance with the a gap can be calculated as: 3. It is possible to add a small gap to the transformer. Gapped transformers are Primary Inductance (µH nominal) = 2.2 * (Primary Turns) 2 94 pulseelectronics.com SPM2007 (03/15) High Frequency Planar Transformers PA09XXNL 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. 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 95 pulseelectronics.com rise) does not exceed its operating temperature. To determine the approximate temperature rise of the transformer, refer to the graphs below. SPM2007 (03/15)
