Core material Ferrite Core and winding loss See www.coilcraft.com/coreloss Terminations RoHS compliant gold over nickel over phos bronze. Other terminations available at additional cost. Weight: 0.61 – 0.67 g Ambient temperature –40°C to +85°C with Irms current, +85°C to +125°C with derated current 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 Packaging 1200/13″ reel; Plastic tape: 16 mm wide, 0.35 mm thick, 12 mm pocket spacing, 4.5 mm pocket depth PCB washing Only pure water or alcohol recommended 6.6 × 6.6 mm footprint; 4.1 mm high shielded inductors Low DCR and excellent current handling 1. Please specify termination and packaging codes: MSS7341-474MLD Termination: L = RoHS compliant gold 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 =1 3″ machine-ready reel. EIA-481 embossed plastic tape (1200 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/HP 8753D network analyzer and a Coilcraft SMD-D test 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.
