Notes
- When ordering, please specify tolerance, termination and screening codes: e.g. AR312RAG39NGPZ.
- 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.
- Q measured using an Agilent/HP 4291A with an Agilent/HP 16197A test fixture or equivalents.
- SRF measured using an Agilent/HP 8753ES network analyzer or equivalent and a Coilcraft CCF1232 test fixture.
- 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.
