1 When ordering, please specify packaging code: e.g. CV9052-ALC
Packaging: C = 7" machine ready reel.
EIA-481 embossed plastic tape (500 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 C instead.
D= 13" reel, machine-ready 
EIA-481 embossed plastic tape. Factory order only (1200 parts per full reel).
2 Inductance tested between pins 1 and 3 at 100 kHz, 0.05 Vrms, 0 Adc
3 Leakage inductance is for the primary, measured at 100 kHz, 0.05 Vrms, 0 Adc with the secondary windings shorted.
4 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Ambient temperature range: −40°C to +85°C
6 Storage temperature range: Component: −40°C to +105°C
Tape and reel packaging: −40°C to +80°C
7 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.
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
