AE312RBAR39
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.

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