Document 920 -1 Shielded Power Inductors – MLC75xx • • • • Soft saturation makes them ideal for VRD/VRM applications Special materials eliminate all thermal aging issues. AEC-Q200 Grade 3 (−40°C to +85°C) Saturation current up to 59 Amps Core material Iron Weight 0.60 – 0.80 g Environmental RoHS compliant, halogen free Terminations RoHS tin-silver over copper. Other terminations available at additional cost. Ambient temperature –40°C to +85°C with Irms current Maximum part temperature +125°C (ambient + temperature rise) 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 PCB washing Tested to MIL-STD-202 Method 215 plus an additional aqueous wash.

When ordering, please specify termination and packaging codes: MLC7540-222MEC Termination: E = RoHS 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.
