1. Inductance is measured at 150 kHz, 0.1 Vrms.
2. DCR is with the secondary windings connected in parallel.
3. Leakage inductance is for the three windings of the primary with the
secondary windings shorted.
4. Turns ratios are with the primary and secondary windings connected in
parallel.
5. DC current at which the inductance drops 10% (typical) from its value
without current.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
