Shielded Power Inductors – SER1590
AEC

Designed for high current, low voltage power supply
applications, the SER1590 Series offers unmatchedelectrical performance in an extremely robust package.

Q200 +85°C

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.		 Inductance2

1. When ordering, please specify termination and packaging codes:
SER1590-152MLD

Termination: L = RoHS compliant tin-silver-copper over copper.
Special order: S = non-RoHS tin-lead (63/37).
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (250 parts per full reel). Quantities less than full
reel available: in tape (not machine ready) or withleader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from B to D.
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 andCoilcraft SMD-D test fixture.
5. DC current at 25°C that causes the specified inductance drop from its
value without current. Click for temperature derating information.
6. Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum
ratings. Click for temperature derating information . When Irms is greaterthan Isat, Isat is the more critical specification, and Irms is shown in graytype. See Temperature Rise vs Current curve on next page.
7. Electrical specifications at 25°C.
