1. When ordering, please specify termination and packaging codes:
MSS7348-105MEC
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: C = 7â³ 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 = 13â³ 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 a Coilcraft SMDâA
fixture in an Agilent/HP 4263B LCR meter.
3. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMDÂâD 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 âSoldering Surface Mount Componentsâ before soldering.
