SMT Power Inductor - SER2000 Series
Designed for high current, low voltage power supply
applications, the SER2000 Series offers unmatched elec-
trical performance in extremely robust packages. This
series is available in six package heights, all sharing the
same footprint. Their flat wire windings provide excep-
tionally low DC resistance and saturation current ratings
as high as100 Amps.
The SER2009 has the lowest profile. Despite measuring
only 0.34 inches (8,64 mm) high, it handles current as
high as 75 Amps. The taller packages provide even
greater current handling capability.

SER2014-202MLD
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.
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.
Part numbers shown in bold type are included in Coilcraft Designer’s
Kit C374.
Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/
HP 4192A or equivalent.
DCR measured on a Keithley 580 micro-ohmmeter.
SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
DC current at which the inductance drops 10% (typ) from its value
without current.
Storage and operating temperature range
−40°C
to +85°C.
Electrical specifications at 25°C.
