  3. Q measured at specified test frequency, using an Agilent/HP 4291A impedance analyzer (or equivalent).
  4. For AT422RAS and AT466RAS: SRF measured using an Agilent/HP 8753ES network analyzer (or equivalent) and the CCF1248 Coilcraft test fixture.

    For AT522RAS and AT573RAS: SRF measured using an Agilent/HP 8753ES network analyzer (or equivalent) and the following Coilcraft test fixture: CCF1199 for AT522RAS 90 nH through 160 nH; and CCF1200 for all others.
  5. Current that causes a 20°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Tolerance:

  • 3 = EEE-INST-002 (Family 3) Level 3
  • 4 = MIL-STD-981 (Family 50) Class B
  • 5 = MIL-STD-981 (Family 50) Class S
    • Screening performed to the document’s latest revision.
    • Screening not available for parts with 2% tolerance.
    • Testing is performed using 155°C as max component temperature.
    • Lot qualification (Group B) available.
    • Testing T and U have been replaced with more detailed codes 4, 5, and 1, 2, 3, respectively. Codes T and U can still be used, if necessary. Custom testing also available.
