| Document 348 Flyback Transformer This flyback transformer was developed specifically for ON Semiconductor's isolated 2 W Bias Supply using the NCP1030, and is specified in Application Note AND8119/D. It is ideal for 48 V telecom and 42 V automotive applications. It features interleaved primary and secondary windings to Inductance at 0 Adc2 10% (H) 120 Inductance at Ipk3 min (H) 102 for ON Semiconductor NCP1030 minimize leakage inductance. It is designed for 35-76 V input. Isolation is 500 Vrms between the primary and secondary windings and between windings and the core. To request free evaluation samples, contact Coilcraft or visit www.coilcraft.com. Leakage Inductance4 max (H) 0.95 Part number1 B0226-EL_ DCR max (Ohms) 0.655 (pins 1 - 4) 0.820 (pins 2 - 3) 0.248 (pins 7 - 8) 0.248 (pins 5 - 6) Turns ratio pri : sec (7-8) pri : sec (5-6) 1 : 0.36 1 : 0.36 Ipk3 (mA) 400 1. When ordering, specify a packaging code: B0226-ELD Packaging: D = 13 machine ready reel. EIA-481 embossed plastic tape (600 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 275 kHz, 0.5 Vrms. 3. Peak primary current drawn at minimum input voltage. 4. Leakage inductance is for the primary winding with the secondary windings shorted. 5. Operating temperature range -40C to +85C. 6. Electrical specifications at 25C. 1 Dot indicates pin 1 B0226-E CCIXXXX 0.400 max 10,16 0.063 1,60 0.079 2,00 0.475 max 12,07 0.235 max 5,97 0.004 / 0,10 1 2 Primary 35 V - 76 V 3 4 8 Sec 1 12 V, 167 mA 7 6 Sec 2 12 V, 3 mA 5 4 3 2 1 5 6 7 8 0.067 1,70 1 0.358 9,09 8 0.079 2,00 0.063 1,60 Recommended Land Pattern Weight: 0.96 g Terminations: Tin-silver over nickel over tin over phos bronze Tape and reel: 600/13 reel 24 mm tape width For packaging data see Tape and Reel Specifications section.
