1. Inductance measured at 500 kHz, 0.1 Vrms,
0 Adc on an Agilent/HP 4284A LCR meter or
equivalent.
2. DCR measured on a Keithley 580 micro-
ohmmeter or equivalent.
3. SRF measured using an Agilent/HP 8753D
network analyzer and a Coilcraft SMD-D
test fixture.
4. DC current at which the inductance drops
the specified amount from its value without
current.
5. Current that causes a the specified
temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount
Components” before soldering.
• Perfect for high current, low voltage power supply applications
• Extremely low DCR; Current handling to >100 Amps
• Higher inductance values than other SER series – up to 33 µH
Core material Ferrite
Core and winding loss See www.coilcraft.com/coreloss
Terminations RoHS compliant tin-silver over copper. Other
terminations available at additional cost.

Caution:
This series is not intended for use
in high vibration or mechanical
shock environments. We advise
using additional means of secur-
ing the part to the circuit board to
ensure its adhesion. Consider our
SER2900 series, which offers
nearly identical electrical charac-
teristics and incorporates a third
mount pad for better stability and
board adhesion.
