SMT Power Inductors - DO3316HC Series
The DO3316HC series has been specially designed for
high current, low voltage DC-DC converter applications.
This simple, rugged design provides current ratings nor-
mally available only in much larger packages — up to
17 Arms for a 0.12 µH part! With its tinned self-leaded
construction, the DO3316HC achieves very low DCR
values and excellent solderability. In addition to the
standard parts shown, custom values are also available.
The DO3316HC series includes features such as tape and
reel packaging and a flat top for pick-and-place handling
that are standard in all Coilcraft SMT power products.
Coilcraft
Designer’s Kit C126
contains three samples each
of the standard parts shown. To order, contact Coilcraft or

Land Pattern
1. Part number on reel label may have a B suffix to indicate that the
reel is not machine ready.
2. Inductance tested at 100 kHz, 0.1 Vrms, 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.
See Qualification Standards section for environmental and test data.
