D124C Series
FIXED INDUCTOR FOR SURFACE MOUNTING
DESCRIPTION
The D124C is a low profile fixed inductor for
use as a DC choke coil. It is recommended
for large current DC-DC converter
applications in consumer electronics
platforms. The low profile (4.3 mm typical)
makes it ideal for use in portable laptop
computers and flat panel displays.

Inductance is measured with a LCR meter 4284A (HP) or equivalent.
DC Resistance is measured with a digital multimeter TR6871 (Advantest) or equivalent.
Maximum allowable DC current is that which causes a 10% inductance reduction from the initial value, or coil temperature to rise by 40
o
C, whichever is
smaller. (Reference ambient temperature 20
