1. Please specify
termination
and
packaging
codes:
MSS7331-104MLC
Termination: L
= RoHS compliant gold over
nickel over phos bronze
Special order:
T
= RoHS tin-silver-copper
(95.5/4/0.5) over tin over nickel
over phos bronze or
S
= non-RoHS tin-lead (63/37)
over tin over nickel over phos
bronze.
Packaging: C
=
7″ machine-ready reel
EIA-
481 embossed plastic tape (350
per full reel).
B
=
Less than full reel
In tape,
but not machine-ready. To have
a leader and trailer added
($25 charge), use code letter C
instead.
D
=
13″ machine-ready reel
EIA-
481 embossed plastic tape.
Factory order only, not stocked
(1500 per reel per full reel).
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using
an Agilent/HP 4284A LCR meter or equivalent.
3. For SRF >13 MHz, SRF measured using an Agilent/
HP 8753D network Analyzer or equivalent. For
SRF <13 MHz, SRF measured using an Agilent/
HP 4192A or equivalent.
4. DC current at 25°C that causes the specified
inductance drop from its value without current.
Click for temperature derating information.
5. Current that causes the specified temperature rise
from 25°C ambient. This information is for reference
only and does not represent absolute maximum
ratings.
Click for temperature derating information.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components”
before soldering.
