• Heavy gauge wire and self-leaded terminations for low DCR
• Saturation current ratings as high as 33.4 A
Core material Ferrite Core and winding loss See www.coilcraft.com/coreloss Terminations RoHS compliant tin-silver over copper. Other terminations available at additional cost. Weight 5.8 – 7.6 g (2.8 –12 µH); 5.7 – 7.0 g (15 –1400 µH) 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 175 per 13″ reel 2.8 –12 µH parts Plastic tape: 44 mm wide, 0.5 mm thick, 24 mm pocket spacing, 12.8 mm pocket depth 15 –1400 µH parts Plastic tape: 32 mm wide, 0.4 mm thick, 24 mm pocket spacing, 12.1 mm pocket depth PCB washing Only pure water or alcohol recommended
1. When ordering, please specify termination and packaging codes:
DO5040H-104MLD Termination: L = RoHS compliant 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: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (175 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. 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using Coilcraft SMD-A fixture in Agilent/HP 4284A impedance analyzer. 3. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD-D test fixture. 4. DC current at which the inductance drops 10% (typ) from its value without current. 5. Current that causes a 40°C temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
