Notes:
(1) Tolerance code as suffix to Pa rt Number:
K = ± 10%, M = ± @ 20%
(2) Q and Inductance ar e measured by Q meter YHP–4342B
(3) The ra ted DC current is that which the inductance value
decreases 10% b y the a pplied DC current, measur ed at
1kHz b y univer sal bridge or equivalent.
(4) Self Resonant Fr equency is measured by Networ k Analyzer
3577A (hp), MS560J (Anr isto) or equivalent.
(5) DC Resistance is measur ed by Digital Multimeter TF6871,
(Adv antest) or equiv alent.
(6) Self Resonant Fr equency is for r eference only.
(7) Pa rts supplied Bulk or Tape and Reel.
