Notes from Tables:
1. The above transformers have been tested and approved by Pulses IC partners and are cited 3. To determine if the transformer is suitable for your application, it is necessary to ensure
in the appropriate datasheet or evaluation board documentation at these companies. To that the te mperature rise of the component (ambient plus temperature rise) does not
determine which IC and IC companies are matched with the above transformers, please exceed its operating temperature. To determine the approximate temperature rise of the
refer to the IC cross reference on the Pulse web page. See the Spyglass transformer matrix transformer, refer to the graphs below.
on the next page for other winding configurations that can be made available. 4. Add suffix T to the part number for Tape & Reel package (i.e. PA0168T).
2. The listed transformers are designed to meet basic insulation (1.4mm creepage and
clearance with 1500Vdc isolation). Lower cost transformers with operational insulation
(1500Vdc isolation with no creepage and clearance spacings) are available. Please contact
Pulse Power Applications Engineering for details.
