720 W Planar Transformer

Document 1217

Document 1217 Revised 07/14/15

1. Inductance is measured at 300 kHz, 1.0 Vrms, 0 Adc.

2. Leakage inductance is for the primary, measured with the secondary

shorted

3. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
