Designed for high current, low voltage power supply ap-
plications, the SER1590 Series offers unmatched electri-
cal 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:
SER1590-102M
LD
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 10% (typ) from its value
without current.
6. Current that causes a 40°C temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Designer’s Kit C366 contains 4 of each value
