Shielded Power Inductors – MSS4020 Document 329 -1 1. When ordering, please specify termination and packaging codes: MSS4020-104MLD Termination: L = RoHS compliant matte tin over nickel over phos bronze. Special order: 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 (2000 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. Designer’s Kit C381 contains 3 each of all values. Core material Ferrite Core and winding loss See www.coilcraft.com/coreloss Terminations RoHS compliant matte tin over nickel over phos bronze. Other terminations available at additional cost. Weight: 81.0 – 87.8 mg Ambient temperature –40°C to +85°C with (40°C rise) Irms current. Maximum part temperature +125°C (ambient + temp rise). Derating. 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 2000/13″ reel; Plastic tape: 12 mm wide, 0.3 mm thick, 8 mm pocket spacing, 2.2 mm pocket depth PCB washing Tested to MIL-STD-202 Method 215 plus an additional aqueous wash.

Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter or equivalent. 3. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD -D test 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.
