Notes
  1. When ordering, specify tolerance, termination and testing codes: e.g. ST336RAA821GRZ.
  2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer or equivalent with Coilcraft-provided correlation pieces.
  3. Q measured using an Agilent/HP 4291A with an Agilent/HP 16197A test fixture or equivalents.
  4. SRF measured on an Agilent 8753ES or equivalent with a Coilcraft CCF1297 test fixture.
  5. DCR measured on a Keithley micro-ohmmeter or equivalent and a Coilcraft CCF858 test fixture.

Tolerance:

  • F = 1%
  • G = 2%
  • J = 5%

Termination:

  • R = Matte tin over nickel over silver-platinum glass frit

  • L = Silver-palladium-platinum glass frit. (Special order, added cost)
  • P = Tin-lead (63/37) over tin over nickel over silver-platinum-glass frit. (Special order, added cost)
  • Q = Tin-silver-copper (95.5/4/0.5) over tin over nickel over silver-platinum-glass frit. (Special order, added cost)
  • C = Tin-lead (63/37) over gold over nickel over moly-mag. (Special order, added cost)
  • F = Tin-silver-copper (95.5/4/0.5) over gold over nickel over moly-mag. (Special order, added cost)
  • S = Tin-lead (63/37) over silver-platinum-glass frit. (Special order, added cost)
  • T = Tin-silver-copper (95.5/4/0.5) over silver-platinum glass frit. (Special order, added cost

Testing:

  • Z = Unscreened
  • Y = Unscreened (SLDC Option A)
  • W = Unscreened (SLDC Option B)
  • H = Coilcraft CP-SA-10001 Group A
  • G = Coilcraft CP-SA-10001 Group A (SLDC Option A)
  • D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
    • All screening performed to the document’s latest revision.
    • Custom screening also available.
