1.When ordering, specify tolerance, termination and testing codes:
ST450RAA333JLZ
Tolerance: F = 1%â G = 2%â 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.
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
2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/
HP 4286 impedance analyzer or equivalent with Coilcraft-provided correla-
tion pieces.
3. Q measured at the same frequency as inductance using an Agilent/
HP 4291A with an Agilent/HP 16197 test fixture or equivalents.
4. SRF measured using an Agilent/HP 8753ES network analyzer or equiva-
lent and a Coilcraft SMD-D test fixture.
5. DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a
Coilcraft CCF859 test fixture.
6. Electrical specifications at 25°C.
