B0226-EL Flyback Transformer
for ON Semiconductor NCP1030

  • Developed specifically for use with On Semiconductor NCP1030 power converter
  • Interleaved primary and secondary windings for low leakage inductance
  • Designed for 35 V to 76 V input
  • Ideal for 48 V telecom and 42 V automotive applications
  • Isolation (hipot) 1500 Vrms, one minute between the primary and secondary windings
  • RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations.

1 When ordering, please specify packaging code: e.g. B0226-ELD
Packaging: D = 13" reel, machine-ready 
EIA-481 embossed plastic tape (600 parts per full reel).
B = Less than full reel
In tape, 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 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Isolation measured from pins 1,2,3,4 to pins 5,6,7,8 and from all pins to the core for one minute.
5 Ambient temperature range: −40°C to +85°C
6 Maximum part temperature: +125°C (ambient + temp rise)
7 Storage temperature range: Component: −40°C to +85°C
Tape and reel packaging: −40°C to +80°C
8 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
9 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info
