Shielded Power InductorsMLC12xx/15xx
• Soft saturation makes them ideal for VRD/VRM applications • Special materials eliminate all thermal aging issues.
Core material Iron Core and winding loss See www.coilcraft.com/coreloss Terminations RoHS tin-silver over copper. Other terminations available at additional cost. Weight MLC12xx 1.91 – 3.04 g; MLC15xx 2.73 – 5.12 g 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. 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 PCB washing Tested to MIL-STD-202 Method 215 plus an additional aqueous wash.

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 plas.
