1. Specify
termination
and
packaging
codes:
MSS7341-224MLD
Termination: L
= RoHS compliant matte tin
over nickel over phos bronze
(current production) 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: D
= 13″ machine-ready reel.
EIA-481 embossed plastic
tape (1200 parts 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 D instead.
2. Inductance measured at 100 kHz, 0.1 Vrms,
0 Adc using a Coilcraft SMD-A fixture in an
Agilent/HP 4263B LCR meter.
3. SRF measured using an Agilent/HP 8753D
network analyzer and a Coilcraft SMD-D test
fixture.
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.
