1. Please specify termination and packaging codes:
MSS1278T-105KLD
Termination: L = RoHS compliant matte tin 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: D = 13â³ machine-ready reel. EIA-481
embossed plastic tape (500 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 tested at 100 kHz, 0.1 Vrms, 0 Adc using
an Agilent/HP 4263B LCR meter or equivalent.
3. DCR measured on a micro-ohmmeter and a
Coilcraft CCF858 test fixture.
4. SRF measured using an Agilent/HP 8753D network
analyzer and a Coilcraft SMDÂâD test fixture.
5. DC current at which the inductance drops the
specified amount from its value without current.
6. Current that causes the specified temperature rise
from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 âSoldering Surface Mount
Componentsâ before soldering.
