1. When ordering, please specify
packaging
code:
JA4220-ALC
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 V, 0 Adc on an Agilent/HP 4192
or equivalent.
3. DCR measured on a micro-ohmmeter.
4. Electrical specifications at 25°C. Measurements are referenced to 50 Ohms.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
