1. When ordering, please specify
termination
and
packaging
codes:
MSS7341T-104MLD
Termination: L
= RoHS compliant matte tin over nickel over phos bronze.
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.
