Base pad: RoHS compliant gold over nickel over phos bronze. Other terminations available at additional cost. Weight SER2915L – 28.5 g; SER2915H – 29.7 g; SER2918H – 35.7 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 25 pieces per tray PCB washing Only pure water or alcohol recommended  Same electrical specifications as Coilcraft’s SER2800  Extremely low DCR; Current handling to >100 Amps  Third mounting pad for greater stability and board adhesion 1. When ordering, specify termination code: SER2915-333KL 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). 2. Inductance measured at 500 kHz, 0.1 Vrms,

0 Adc on an Agilent/HP 4284A LCR meter or

equivalent. 3. DCR measured on a Keithley 580 micro- ohmmeter or equivalent. 4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. 5. Peak dc current at which the inductance drops the specified amount from its value without current. When Isat rating is less than Irms, Isat is the more critical specification. 6. Current that causes the specified temperature rise from 25°C ambient. When Irms is greater than Isat, Isat is the more critical specification, and Irms is shown in gray type. See Temperature Rise vs Current curve on next page. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
