1. Please specify
termination
and
packaging
codes:
MSS1048-334KLC
Termination: L
= RoHS compliant matte tin over nickel
over copper.
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 (200 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 C instead.
D
= 13″ machine-ready reel. EIA-481
embossed plastic tape. Factory
order only, not stocked (800 parts
per full reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc
using an Agilent/HP 4263B LCR meter or equivalent.
3. SRF measured using an Agilent/HP 4192A impedance
analyzer or equivalent.
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.
