1. 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 Coilcraft 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.
