Notes
  1. Please specify tolerance, termination and screening codes: e.g. ST450PHF105KLZ.
  2. Inductance measured at 100 kHz, 0.1 Vrms, using Coilcraft SMD-A fixture in Agilent/HP 4263B impedance analyzer or equivalent.
  3. DCR measured on micro-ohmmeter and a Coilcraft CCF859 test fixture.
  4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft CCF1301 test fixture.
  5. DC current at which the inductance drops 10% (typ) from its value without current.

Tolerance:

  • J = 5%
  • K = 10%

Termination:

  • L = Silver-palladium-platinum-glass frit terminations.
  • S = Tin-lead (63/37). (Special order, added cost)

Screening:

  • Z = Unscreened
  • Y = Unscreened (SLDC Option A)
  • W = Unscreened (SLDC Option B)
  • H = Group A screening per Coilcraft CPSA-10001
  • 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.
