1 When ordering, please specify a packaging code: e.g. JA4220-ALC
  Termination: L = RoHS compliant tin-silver-copper over silver-platinum-glass frit.
Special order, added cost: S = non-RoHS tin-lead (63/37).
  Packaging: C = 7" machine ready reel.
EIA-481 embossed plastic tape (750 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" machine ready reel.
EIA-481 embossed plastic tape. Factory order only, not stocked (3000 parts per full reel).
2 Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4192 or equivalent.
3 DCR measured on a micro-ohmmeter at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Ambient temperature range: −40°C to +85°C
5 Storage temperature range: Component: −40°C to +85°C
Tape and reel packaging: −40°C to +80°C
6 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.
7 Electrical specifications at 25°C. Measurements are referenced to 50 Ohms.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
