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 25°C that causes the specified inductance drop from its
value without current. Click for temperature derating information.
5. Current that causes the specified temperature rise from 25°C ambient.
This information is for reference only and does not represent absolute
maximum ratings. Click for temperature derating information.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
