1. When ordering, specify
tolerance, termination
and
testing
codes:
ST235RAGR10GLZ
Tolerance: G
= 2%
J
= 5%
Termination: L
= RoHS compliant silver-palladium-platinum-glass frit.
Special order:
T
= RoHS tin-silver-copper (95.5/4/0.5) over silver-
palladium-platinum-glass frit
S
= non-RoHS tin-lead (63/37) over silver-palladium-
platinum-glass frit.
R
= Tin over nickel over silver-platinum-glass frit.
Q
= RoHS tin-silver-copper (95.5/4/0.5) over tin over
nickel over silver-platinum-glass frit.
P
= non-RoHS tin-lead (63/37) over tin over nickel over
silver-platinum-glass frit.
Testing:
Z
= COTS
H
= Group A screening per Coilcraft CP-SA-10001
2. Inductance measured at 250 MHz using a Coilcraft SMD-F fixture in
an Agilent/HP 4286A impedance analyzer or equivalent with Coilcraft-
provided correlation pieces.
3. Q measured 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
equivalent and a Coilcraft CCF1232 test fixture.
5. DCR measured on a Keithley 580 micro-ohmmeter and a Coilcraft
CCF1192 test fixture.
6. Electrical specifications at 25°C.
