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-silvercopper (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.
