SMT Power Inductors - DH3316 Series
These power inductors feature a small footprint, magnetic
shielding and very high efficiency, making them ideal for
high performance DC-DC converter applications.
Like all Coilcraft surface mount power inductors, they are
designed with a flat top for reliable pick and place operations.
The terminations wrap around the end of the base, ensuring
a sound solder fillet and simplifying inspection.
Saturation current ratings up to 10 A and rms current ratings
as high as 6 A are available. Very low DC resistance keeps
power losses to a minimum.
In addition to the standard values shown here, DH3316
inductors in custom values are also available. For free
evaluation samples or to order, contact Coilcraft or visit

Packaging: D
= 13″ machine ready reel. EIA-481 embossed plastic
tape (1000 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 tested at 0.1 Vrms, 100 kHz, 0 Adc.
3. SRF measured using Agilent/HP 8753D network analyzer.
4. DC current at which the inductance drops 10% (typ) from its value
without current.
5. Average current for a 40°C rise above 25°C ambient.
6. Operating temperature range
−40°C
to +85°C
7. Electrical specifications at 25°C
