Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic tape (175 parts per full reel). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2. Inductance is for the primary, measured at 300 kHz, 0.7 Vrms. For the GA3568-DL inductance is per winding. 3. Peak primary current drawn at minimum input voltage. 4. DCR for the secondary is with the windings connected in parallel. For GA3568-DL DCR for the primary is with both windings connected in parallel. 5. Leakage inductance is for the primary windings with the secondary windings shorted. 6. Turns ratios are for the primary (windings connected in parallel for the GA3568-DL) and with the secondary windings connected in parallel. 7. Output of the secondary is with the windings connected in parallel. Bias winding output is 5 V, 20 mA. 8. Electrical specifications at 25C.
