1. Please specify
termination
and
packaging
codes:
MSS6122-104MLC
Termination: L
= RoHS compliant matte tin over nickel
over phos bronze (current produc-
tion) or gold over nickel over phos
bronze (prior production)
Special order:
T
= RoHS tin-silver-copper
(95.5/4/0.5) over gold over nickel
over phos bronze or
S
= non-RoHS tin-lead (63/37) over
gold over nickel over phos bronze.
Packaging: C
=
7″ machine-ready reel
EIA-481
embossed plastic tape (500 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 4263B LCR meter or equivalent.
3. SRF measured using an Agilent/HP 4191A or equilvalent.
4. DC current at which the inductance drops the specified
amount from its value without current.
5. Current that causes the specified temperature rise
from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components”
before soldering.
