When ordering, specify tolerance, termination and testing codes: ST312RAAR39JLZ 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-platinum-glass frit. T = Tin-silver-copper (95.5/4/0.5) over silver-platinum- glass frit. R = Tin over nickel over silver-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. Testing: Z = COTS H = Screening per Coilcraft CP-SA-10001

1. 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 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 and a Coilcraft CCF1232 test fixture. 5. DCR measured on a Keithley 580 micro-ohmmeter and a Coilcraft CCF1010 test fixture. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. Document ST195-2 Revised 11/06/12
