PFC Boost Inductor
for ON Semiconductor NCP1606

  • Developed for ON Semiconductor NCP1606 PFC controller.
  • Designed to operate in 100 Watt applications.
  • Auxiliary winding provides Zero Current Detection (ZCD) information.
  • Referenced as LBOOSTin application note AND8282/D.
  • Also see JA4224-AL for NCP1607 and NCP1608.
  • 1000 Vrms isolation winding to winding and from each winding to the core.

1 Inductance measured at 100 kHz, 0.1 V, 0 Adc using an Agilent/HP 4263B impedance analyzer or equivalent.
2 DCR measured on Cambridge Technology micro-ohmmeter. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
3 Leakage inductance is for the primary and measured with pins 4 and 8 shorted.
4 Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
5 Ambient temperature range: −40°C to +85°C with Irms current
6 Storage temperature range: Component: −40°C to +85°C
Packaging trays: −40°C to +80°C
7 Maximum part temperature: +125°C (Ambient + temperature rise)
8 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
