Notes
  1. When ordering, specify tolerance, termination and screening codes: e.g. ST450RAA333JRZ.
  2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/ HP 4286 impedance analyzer or equivalent with Coilcraft-provided correlation pieces.
  3. Q measured at the same frequency as inductance using an Agilent/ HP 4291A with an Agilent/HP 16193 test fixture or equivalents.
  4. SRF measured using an Agilent/HP 8753ES network analyzer or equivalent and a Coilcraft SMD-D test fixture.
  5. DCR measured on a micro-ohmmeter.

Tolerance:

  • G = 2%
  • J = 5%

Termination:

  • R = Matte tin over nickel over silver-platinum glass frit
  • L = Silver-palladium-platinum glass frit.
  • P = Tin-lead (63/37) over tin over nickel over silver-platinum-glass frit.
  • Q= Tin-silver-copper (95.5/4/0.5) over tin over nickel over silver-platinum-glass frit.
  • S = Tin-lead (63/37) over silver-platinum-glass frit.
  • T = Tin-silver-copper (95.5/4/0.5) over silver-platinum glass frit.

Screening:
