1. When ordering, please specify
termination
and
packaging
codes:
MLC1245-402MLC
Termination: L
= RoHS compliant tin-silver 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.
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.
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-A fixture in an Agilent/HP 4284A LCR meter.
3. SRF measured using an Agilent/HP4291A impedance analyzer and a Coilcraft 16193 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.
