1. Packaging: D = 13″ machine-ready reel; EIA-481 embossed plastic
tape (ZA9423-33N, 500 parts per full reel;
ZA9423-66N, 450 parts per full reel).
Quantities less than full reel available: in tape (notmachine ready) or with leader and trailer ($25 charge).
2. Inductance measured at 1.0 MHz, 0.1 Vrms, 0 A using an Agilent/HPHP4291A impedance analyzer with an Agilent/HP 16193A test fixture orequivalents.
3. Q measured at the specified frequency using an Agilent/HP 4291A
impedance analyzer or equivalent.
