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.

1. 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.
