■ Combines the exceptionally high Q of an air core inductor
with the rugged construction of a ceramic body component.
■ Inductance values: 1.15 nH – 10.4 nH
■ Provides intermediate inductance values not available in
Coilcraft’s 0603, 0402 or 0906 product families

1. When ordering, please specify termination and testing codes:
ST319RAD10NJLZ
Termination: L = RoHS compliant silver-palladium-platinum glass frit.
Special order:
S = Tin-lead (63/37) over silver-palladium-platinum-glass
frit.
T = Tin-silver-copper (95.5/4/0.5) over silver-palladium-
platinum-glass frit.
R = Tin over nickel over silver-platinum-glass frit.
P = Tin-lead (63/37) over tin over nickel over silver-plati-
num-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 at 500 MHz using a Coilcraft SMD-A fixture in an
Agilent/HP 4286 impedance analyzer with Coilcraft-provided correlation
pieces.
3. Q measured at 500 MHz using an Agilent/HP 4291A with an Agilent/
HP 16193 test fixture.
4. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD­‑D test fixture.
5. DCR measured on a CambridgeTechnology micro-ohmmeter and a
Coilcraft CCF858 test fixture.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
