1. Please specify termination and packaging codes:
MSS1038-105KLC
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 (250 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 (1000 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 8753D or equivalent.
4. DC current at which the inductance drops the speci-
fied 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.
