Shielded Power Inductors–MLC1770
• Soft saturation makes them ideal for VRD/VRM applications
• Special materials eliminate all thermal aging issues.
• Saturation current up to 64 Amps

1. When ordering, please specify termination and packaging codes:
MLC1770-282MEC
Termination: E = RoHS compliant tin-silver over copper
Special order, added cost: T = RoHS tin-silver-
copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Packaging: D = 13″ machine-ready reel. EIA‑481 embossed plastic
tape (400 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 measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft
SMD‑A fixture in an Agilent/HP 4263B LCR meter.
3. SRF measured using an Agilent/HP4291A impedance analyzer and an
Agilent/HP 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.
Core material Iron
Core and winding loss Go to core loss calculator
Environmental RoHS compliant, halogen free
Weight 7.8 – 8.0 g
Terminations RoHS compliant tin-silver (96.5/3.5) over copper. Other
terminations available at additional cost.
Ambient temperature –40°C to +85°C with Irms current
Maximum part temperature: The part may be operated without
damage as long its temperature (ambient + self-heating) does not
exceed +125°C.
Storage temperature Component: –40°C to +125°C.
Tape and reel packaging: –40°C to +80°C
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
Packaging 400 per 13″ reel Plastic tape: 24 mm wide, 0.4 mm thick,
24 mm pocket spacing, 7.0 mm pocket depth
PCB washing Tested to MIL-STD-202 Method 215 plus an additional
aqueous wash. See Doc787_PCB_Washing.pdf.
