Notes
  1. When ordering, specify tolerance and testing codes: e.g. AT446RAT27NGSZ.
  2. Inductance measured at 250 MHz on an Agilent/HP 4286A or equivalent with a Coilcraft SMD-A test fixture and correlation.
  3. Q measured at 250 MHz on an Agilent/HP 4291A or equivalent with a 16193A test fixture or equivalent.
  4. SRF measured on an Agilent/HP 8753ES or equivalent with a Coilcraft CCF1268 test fixture.
  5. DCR measured on a Keithley 580 Micro-Ohmmeter or equivalent.

Tolerance:

  • G = 2%
  • J = 5%

Screening:

  • Z = Unscreened
  • H = Group A screening per Coilcraft CP-SA-10001
  • F = Screening per ESCC 3201
  • 1 = EEE-INST-002 (Family 3) Level 1
  • 2 = EEE-INST-002 (Family 3) Level 2
  • 3 = EEE-INST-002 (Family 3) Level 3
  • 4 = MIL-STD-981 (Family 50) Class B
