Notes
  1. When ordering, please specify tolerance, termination and testing codes: e.g. CP312RAB822JLZ.
  2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/HP4286A 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 using an Agilent/HP 8753ES network analyzer or equivalent and a Coilcraft SMD-D test fixture.
  5. DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a Coilcraft CCF1010 test fixture.

Tolerance:

  • G = 2%
  • J = 5%

Termination:

  • L = Silver-palladium-platinum-glass frit.
  • T = Tin-silver-copper (95.5/4/0.5). (Special order, added cost)
  • S = Tin-lead (63/37). (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.
