AR312RAG Series

Outgassing Compliant Chip Inductors

Coilcraft AR312RAG Series offers higher Q and lower DCR than other 0603 inductors.
  • Highest SRF values – as high as 16 GHz.
  • High temperature materials allow operation in ambient temperatures up to 155°C.
  • Passes NASA low outgassing specifications.
  • Standard tin-lead (Sn-Pb) terminations ensures the best possible board adhesion. Note: Nickel barrier termination (tin-lead over tin over nickel over silver-platinum-glass frit, termination code P) is recommended for hand soldering applications.
  • Tin-lead (63/37) over tin over nickel over silver-platinum-glass frit terminations. Other terminations are also available.

Notes
  1. When ordering, please specify tolerance, termination and screening codes: e.g. AR312RAG39NGPZ.
  2. Inductance measured at specified test frequency using a Coilcraft SMD-A test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286A impedance analyzer or equivalent.
  3. Q measured using an Agilent/HP 4291A with an Agilent/HP 16197A test fixture or equivalents.
  4. SRF measured using an Agilent/HP 8753ES network analyzer or equivalent and a Coilcraft CCF1232 test fixture.
  5. DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a Coilcraft CCF1010 test fixture.

Tolerance:

  • G= 2%
  • J = 5%

Termination:

For hand soldering applications, the nickel barrier termination (tin-lead over tin over nickel over silver-platinum-glass frit, termination code P) is recommended. Exposed gold or tin in the terminations migrates into the solder.
  • P = Tin-lead (63/37) over tin over nickel over silverplatinum-glass frit.
  • C = Tin-lead (63/37) over gold over nickel over moly-mag.
  • S = Tin-lead (63/37) over leach-resistant silver-platinumglass frit.
  • A = Gold over nickel over moly-mag.
  • L = Silver-palladium-platinum-glass frit.

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.
