They are specified in application note AND8161/D along with Coilcraft’s DS3316P-103 and DS3316P-102 shielded inductors. Refer to the separate data sheet for additional information about the DS3316 Series of inductors The C0972-AL features very low DCR, excellent leak- age inductance and 1500 V Isolation from the primary and auxiliary windings to the secondary. The B0754-AL is the output inductor and features four separate windings connected in parallel to minimize power losses and to limit temperature rise.
