When ordering, specify termination and packaging codes: SPT20L-112MLD 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. Body size 1: 750 per full reel. Body sizes 2–3: 350 per full reel. Body size 4: 300 per full reel. Body sizes 5–6: 250 per full reel. Body sizes 7–8: 200 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 tested at 100 kHz, 0.1 Vrms on Agilent/ HP 4192A. 3. Inductance with Isat current applied tested at 100 kHz, 0.1 Vrms on Agilent/HP 4284A. 4. SRF measured on Agilent/HP 8753ES network analyzer. 5. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. 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. Ambient temperature –40°C to +85°C Maximum part temperature: The part temperature should not exceed +85°C (ambient + self-heating). Prolonged operation above +85°C may result in a permanent increase in core loss and part failure due to thermal aging of the core material. Storage temperature Component: –40°C to +85°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 PCB washing Only pure water or alcohol recommended Toroid winding eliminates stray electromagnetic emissions Two versions: Standard, current ratings up to 8 Amps; High current, with ratings up to 13.9 Amp
