Notes
- When ordering, specify tolerance, termination and screening codes: e.g. ST235RAG22NGRZ.
- Inductance measured at 250 MHz using a Coilcraft SMD-F fixture in an Agilent/HP 4286 impedance analyzer with Coilcraft-provided correlation pieces.
- Q typ measured using an Agilent/HP 4287A with an Agilent/HP 16197 test fixture.
- SRF measured using an Agilent/HP 8753ES network analyzer or equivalent and a Coilcraft CCF1232 test fixture.
- DCR measured on a micro-ohmmeter and a Coilcraft CCF1010 test fixture.
Tolerance:
- G = 2%
- J = 5%
Termination:
- R = Matte tin over nickel over silver-platinum glass frit.
- A = Gold over nickel over moly-mag.
- L = Silver-palladium-platinum glass frit.
- P = Tin-lead (63/37) over tin over nickel over silver-platinum-glass frit.
- Q= Tin-silver-copper (95.5/4/0.5) over tin over nickel over silver-platinum-glass frit.
