1. Please specify
termination
and
packaging
codes:
MSS5131-394MLC
Termination: L
= RoHS compliant gold over nickel over
phos bronze
Special order:
T
= RoHS tin-silver-copper (95.5/4/0.5)
or
S
= non-RoHS tin-lead (63/37).
Packaging: C= 7″ machine-ready reel
EIA-481
embossed plastic tape (600 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 (2500 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 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.
