Notes
  1. When ordering, please specify termination and screening codes: e.g. ST251PHJ102MRZ.
  2. Inductance tested at 7.9 MHz, 0.1 Vrms using a Coilcraft SMD-F test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286 impedance analyzer.
  3. DCR measured on a micro-ohmmeter.
  4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
  5. DC current at 25°C that causes the specified inductance drop from its value without current. Click for temperature derating information.
  6. Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.     Click for temperature derating information.

Termination:

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

Screening:

  • Z = Unscreened
  • H = Group A screening per Coilcraft CP-SA-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.
