When ordering, specify tolerance, termination and testing codes: ST573RAS501JLZ Tolerance: G = 2% J = 5% Termination: L = RoHS compliant tin-silver (96.5/3.5) over copper. Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) over copper or S = non-RoHS tin-lead (63/37) over copper. Testing: Z = COTS H = Screening per Coilcraft CP-SA-10001 2. Inductance measured at specified test frequency, 0.1 Vrms, 0 A using an Agilent/HP 4287A LCR meter with the Coilcraft CCF1197A test fixture. 3. Q measured at specified test frequency, using an Agilent/HP 4291A impedance analyzer. 4. SRF measured using an Agilent/HP 8753 network analyzer and Coil- craft CCF1200 test fixture. 5. Current that causes a 20°C temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
