Other terminations available at additional cost. Weight 0.30 g Ambient temperature –40°C to +125°C 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 250/7″ reel; 1000/13″ reel Plastic tape: 16 mm wide, 0.35 mm thick, 12 mm pocket spacing, 5.0 mm pocket depth PCB washing Only pure water or alcohol recommended Part number1 CJ5143-AL_ Inductance at 0 A2 ±10% (µH) 15.0 Inductance at Ipk3 min (µH) 13.5 Leakage inductance4 max (µH) 0.3 DCR max (Ohms) pri sec 1.0 25 1. When ordering, please specify termination and packaging codes: CJ5143-ALC Termination: L = RoHS compliant tin-silver (96.5/3.5) over copper. Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) over copper or S = non-RoHS tin-lead (63/37) over copper. Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic tape (250 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. Factory order only, not stocked (1000 parts per full reel). 2. Inductance measured at 100 kHz, 0.1 Vrms. 3. Peak primary current drawn at minimum input voltage. 4. Leakage inductance is for the primary winding with the secondary winding shorted. 5. Electrical specifications at 25°C.
