1. When ordering, please specify termination and packaging codes:
2. Inductance measured at 250 kHz, 0.4 Vrms.
3. DCR for the primary is with the windings connected on parallel.
4. DC current at which inductance drops the specified amount from its value without current.
5. Current that causes the specified temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
