Notes
- When ordering, specify tolerance, termination and testing codes: e.g. ST413RADR10GLZ.
- Inductance measured at 50 MHz using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer or equivalent with Coilcraft-provided correlation pieces.
- Q measured using an Agilent/HP 4291A with an AgilentHP 16197A test fixture or equivalents.
- SRF measured using an Aglilent/HP 8753ES network analyzeror equivalent and a Coilcraft SMD-D test fixture.
- DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a Coilcraft CCF858 test fixture.
Tolerance:
- F = 1%
- G = 2%
- J = 5%
Termination:
- L = Silver-palladium-platinum glass frit.
- S = Tin-lead (63/37) over silver-platinum-glass frit. (Special order, added cost)
- T = Tin-silver-copper (95.5/4/0.5) over silver-platinumglass frit. (Special order, added cost)
Testing:
- Z = Unscreened
- H = Group A screening per Coilcraft CP-SA-10001
Custom screening also available.
