Notes
  1. When ordering, specify tolerance, termination and testing codes: e.g. ST336RAG821JRZ.
  2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/ HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
  3. Tolerances in bold are stocked for immediate shipment.
  4. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture.
  5. SRF measured using an Agilent/HP 8720D network analyzer and a Coilcraft SMD -D test fixture.
  6. DCR measured on a Cambridge Technology micro-ohmmeter and a Coilcraft CCF858 test fixture.
  7. Current that causes a 15°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Tolerance:

  • G = 2%
  • J = 5%

Termination:

  • R = Matte tin over nickel over silver-platinum-glass frit.
  • Q = Tin-silver-copper (95.5/4/0.5) over tin. (Special order, added cost)
  • P = non-RoHS tin-lead (63/37) over tin. (Special order, added cost)

Testing:

  • Z = Unscreened
  • H = Group A screening per Coilcraft CP-SA-10001
All screening performed to the document’s latest revision.
Custom screening also available.
