AE312RBA Series

Molded Chip Inductors

The AE312RBA Series is not recommended for new designs, but existing customers will continue to be supported. As an alternative, we recommend the AR312RAA Series which is a drop-in replacement with improved electrical performance due to lower DCR.
Our AE312RBA Series features exceptional Q and high SRFs, DCR and current carrying characteristics.
  • Outstanding self-resonant frequency.
  • Passes NASA low outgassing (Outgassing meets ASTM E595).
  • Fits standard 0603 footprint.
  • Gold over nickel terminations. (Tin-lead (63/37) and tin-silvercopper are also available.)

Specifications

Electrical specifications at 25°C.

Part is not compliant with MIL-STD-981 Family 50, Class S due to wire gauge.

Notes
  1. When ordering, specify termination and screening codes: e.g. AE312RBAR39JAZ.
  2. Inductance measured using a Coilcraft SMD-A test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286A impedance analyzer or equivalent.
  3. Q measured at the same frequency as inductance using an Agilent/HP 4291A with an Agilent/HP 16197A test fixture or equivalents.
  4. SRF measured using an Agilent/HP 8753ES network analyzer and a Coilcraft CCF1232 test fixture.
  5. DCR measured on a Keithley 580 micro-ohmmeter and a Coilcraft CCF1010 test fixture.

Termination:

  • A = Gold over nickel over moly-mag.
  • C = Tin-lead (63/37) over gold over nickel over moly-mag.
  • F = Tin-silver-copper (95.5/4/0.5) over gold over nickel over moly-mag.

Screening:

  • Z = Unscreened
  • H = Coilcraft CP-SA-10001 Group A
  • 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
  • 5 = MIL-STD-981 (Family 50) Class S
  • F = ESCC3201 (F4 operational life performed at 90°C)
  • Screening performed to the document’s latest revision.
  • 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.
  • Country of origin restrictions available; prefix options G or F.
