0805 CHIP INDUCTORS
Chip Inductors for Critical Applications
ST336RAD
These inductors provide exceptional Q values, even at
high frequencies. They have a ceramic body and wire
wound construction to provide the highest SRFs, tight
inductance tolerance and batch consistency.
Part number
1
This robust version of Coilcraft’s standard 0805HQ series
features high temperature materials that allow operation
in ambient temperatures up to 155°C.

1. When ordering, specify
tolerance, termination
and
testing
codes:
ST336RAD51NGLZ
Tolerance:
F
= 1%
G
= 2%
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.
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
equivalent and a Coilcraft SMD-D test fixture.
5. DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a
Coilcraft CCF858 test fixture.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
