Other terminations available at additional cost. Ambient temperature -40C to +125C with Irms current, +125C to +165C with derated current Storage temperature Component: -40C to +125C. Packaging: -40C to +80C Resistance to soldering heat Max three 40 second reflows at +260C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / 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 High Isat for high Isat applications Part number1 SER1412-301ME_ SER1412-501ME_ SER1412-681ME_ SER1412-102ME_ SER1412-152ME_ SER1412-202ME_ SER1412-362ME_ Inductance2 20% (H) 0.30 0.50 0.68 1.0 1.5 2.0 3.6 DCR typ3 (mOhms) 1.30 1.30 1.30 1.30 1.30 1.30 1.30 SRF DCR max3 typ4 (mOhms) (MHz) 1.43 154 1.43 122 1.43 100 1.43 78 1.43 62 1.43 50 1.43 35 10% drop 85.0 52.0 40.0 29.0 22.0 17.0 11.0 Isat (A)5 20% drop 85.0 54.5 41.0 31.5 24.0 19.0 12.1 30% drop 85.0 55.5 42.3 32.5 25.0 20.0 12.1 Irms (A)6 20C 40C rise rise 30 37 30 37 30 37 30 37 30 37 30 37 30 37 Height max (inches / mm) 0.498 / 12,66 0.498 / 12,66 0.498 / 12,66 0.498 / 12,66 0.498 / 12,66 0.498 / 12,66 0.498 / 12,66 Low DCR for high Irms applications Part number1 SER1408-301ME_ SER1408-501ME_ SER1408-681ME_ SER1408-102ME_ SER1410-152ME_ SER1410-202ME_ Inductance2 20% (H) 0.30 0.50 0.68 1.0 1.5 2.0 DCR typ3 (mOhms) 0.48 0.48 0.48 0.48 0.90 0.90 DCR max3 (mOhms) 0.55 0.55 0.55 0.55 0.99 0.99 SRF typ4 (MHz) 140 83 63 48 53 45 10% drop 38.0 25.5 20.0 11.2 17.0 12.0 Isat (A)5 20% drop 39.5 29.5 22.2 14.0 19.0 15.0 30% drop 40.5 30.5 22.8 15.5 20.5 16.0 Irms (A)6 20C 40C rise rise 38 42 38 42 38 42 38 42 33 39 33 39 Height max (inches / mm) 0.325 / 8,26 0.325 / 8,26 0.325 / 8,26 0.325 / 8,26 0.416 / 10,56 0.416 / 10,56 1. When ordering, please specify termination and packaging codes: SER1410-202MED Termination: E = 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. 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 measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4263B 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. DC current at which the inductance drops the specified amount from its value without current. 6. Current that causes the specified temperature rise from 25C ambient. 7. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
