Notes
  1. When ordering, please specify termination and screening codes: e.g. ST220RAA34NJLZ.
  2. Inductance measured at 250 MHz using a Coilcraft SMD-F fixture in an Agilent/HP 4286 impedance analyzer with Coilcraft-provided correlation pieces.
  3. For Q min: Q measured at 250 MHz using an Agilent/HP 4291A with an Agilent/ HP 16197A test fixture or equivalents.
    For Q typ: Q measured using an Agilent/HP 4287A with an Agilent/HP 16193 test fixture.
  4. SRF measured using an Agilent/HP 8722ES network analyzer and a test fixture with a 0.017″ air gap.
  5. DCR measured on a micro-ohmmeter and a Coilcraft CCF858 test fixture.
  6. Current that causes a 30°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
