1. When ordering, please specify termination and testing codes:
ST312RAM103JRZ
Termination:R=RoHS compliant matte tin over nickel over silverplatinum-glass frit.
Special order:
Q = RoHS tin-silver-copper (95.5/4/0.5) over tin over
nickel over silver-platinum-glass frit or
P = non-RoHS tin-lead (63/37) over tin over nickel over
silver-platinum-glass frit.
Testing:Z=COTS
H=Screening per Coilcraft CP-SA-10001
2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/
HP 4286A impedance analyzer or equivalent with Coilcraft-provided
correlation pieces.
3. Q measured at the same frequency as inductance 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 SMD-D 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.
