1 When ordering, please specify termination and packaging codes: e.g. FA2659-ALC
  Termination: L = RoHS compliant tin-silver over tin over nickel over phos bronze
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Packaging: C = 7" reel, machine-ready 
EIA-481 embossed plastic tape (175 parts 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, not stocked (750 parts per full reel).
2 Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc
3 Leakage inductance measured at 100 kHz, 0.1 Vrms with secondary pins shorted.
4 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Based on Bsat of the core at 25°C and number of turns of the primary.
6 SRF measured with coils connected in series using an Agilent/HP 4192 or equivalent.
7 Ambient temperature range: −40°C to +125°C
8 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
9 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.
10 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.
