Document 657 -1 SMT PFC Boost Inductor For ON Semiconductor NCP1606 PFC Controller • Designed to operate in 100 Watt applications. • Referenced as LBOOST in application note AND8282/D. • Auxiliary winding provides zero current detection (ZCD) information and can also supply power to the NCP1606. • 500 Vrms winding to winding and winding to core isolation Core material Ferrite Terminations RoHS compliant tin-silver over tin over nickel over phos bronze. Other terminations available at additional cost. Weight 27 g Ambient temperature –40°C to +85°C with Irms current, +85°C to +125°C with derated current Storage temperature Component: –40°C to +125°C. Packaging: –40°C to +80°C Resistance to soldering heat Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 85% relative humidity) Failures in Time (FIT) / Mean Time Between Failures (MTBF) 38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332 Packaging 24 parts per tray PCB washing Only pure water or alcohol recommended Part number GA2972-AL Inductance1 ±10% (µH) 330 DCR max (Ohms) pri aux 0.30 0.35 SRF2 (MHz) Turns ratio pri : aux 1.2 8:1 1. Inductance measured at 100 kHz, 1.1 Vrms, 0 Adc using an Agilent/ HP 4263B impedance analyzer or equivalent. 2. SRF tested on an Agilent/HP 4192A. 3. DC current at which the inductance drops the specified amount from its value without current. 4. Current that causes the specified temperature rise from 25°C ambient. 5. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
