1. When ordering, specify tolerance, termination and testing codes:
ST312RAGR39GLZ
Tolerance:F=1% G = 2% J = 5%
Termination:L=RoHS compliant silver-palladium-platinum-glass frit.
Special order:
S=Tin-lead (63/37) over silver-palladium-platinumglass frit.
T=Tin-silver-copper (95.5/4/0.5) over silver-palladiumplatinum-glass frit.
Testing:Z=COTS
H=Screening per Coilcraft CP-SA-10001
2. Inductance measured at 250 MHz 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.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
