Document 289 -1 Shielded Power Inductors – SER1590 Designed for high current, low voltage power supply applications, the SER1590 Series offers unmatched electrical performance in an extremely robust package. With their heavy flat wire windings, these inductors have exceptionally low DC resistance and offer saturation current ratings up to 50 Amps. Winding to core isolation is 300 Vrms.

When ordering, please specify termination and packaging codes: SER1590-102MLD 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 (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 D instead. 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/ HP 4284A LCR meter or equivalent. 3. DCR measured on a Keithley 580 micro-ohmmeter. 4. SRF measured using an Agilent/HP 8753D network analyzer and 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 a 40°C 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.
