1. Inductance measured at 200 kHz, 1.0 Vrms, 0 Adc using an Agilent/HP 4263B
impedance analyzer or equivalent.
2. Peak primary current drawn at minimum input voltage.
3. DCR is with all windings connected in parallel.
4. Current that causes the specified temperature rise from 25°C ambient. This infor-
mation is for reference only and does not represent absolute maximum ratings
5. Electrical specifications at 25°C.
Refer to Doc 362 âSoldering Surface Mount Componentsâ before soldering.
