Designer’s Kit C375 contains 3 each of all values Core material Ferrite Core and winding loss See www.coilcraft.com/coreloss Terminations RoHS compliant silver-palladium-platinum-glass frit. Other terminations available at additional cost. Weight 28.0 – 31.3 mg Ambient temperature –40°C to +85°C with Irms current, +85°C to +110°C with derated current Storage temperature Component: –40°C to +110°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 1000/7″ reel; 3500/13″ reel Plastic tape: 12 mm wide, 0.23 mm thick, 8 mm pocket spacing, 1.37 mm pocket depth Recommended pick and place nozzle OD: 3.3 mm; ID: ≤1.65 mm PCB washing Tested with pure water or alcohol only. For other solvents, see Doc787_PCB_Washing.pdf.
1. When ordering, please specify termination and packaging codes:
LPO3310-473MLC Termination: L = RoHS compliant silver-palladium-platinum-glass frit
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 (1000 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 C instead. D = 13″ machine-ready reel. EIA-481 embossed plastic tape (3500 parts per full reel). 2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4192A. 3. DCR measured on a micro-ohmmeter. 4. SRF measured using Agilent/HP 8753ES or equivalent. 5. DC current at which the inductance drops 10% (typ) from its value without current. 6. Current that causes a 25°C temperature rise from 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
