Shielded Power Inductors – DT1608C
The Coilcraft DT1608 Series is magnetically shielded
and the materials used provide natural heat sinking. This
allows these parts to be used at relatively high currents.
Even at 150% of rated current, the temperature rise is
less than 15°C.
Because of their “swinging” inductance vs current characteristics, the DT1608 Series can be used as ultra high
L inductors at zero or low current.
For new designs, consider the LPS4018 as an alternative
to this series. The LPS4018 series is more cost effective, features a smaller footprint, lower profile and better
current handling. We will continue to manufacture and
support the DT1608C indefinitely.

1. When ordering, please specify termination and packaging codes:
DT1608C-106MLC
Termination:L=RoHS compliant gold over nickel over moly-manganese.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
Packaging:C
=7″ machine-ready reel. EIA-481 embossed plastic
tape (750 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 C instead.
D
=13″ machine-ready reel. EIA-481 embossed plastic
tape (2500 parts per full reel).

2. Inductance tested at 0.1 Vrms, 100 kHz, 0 Adc.
3. Measured at the rated current. Refer to L vs Current curves for details.
4. Average maximum allowable current. DT Series inductors are designed
for current spikes as high as twice the current rating.
5.Ambient temperature range: –40°C to +85°C
6.Storage temperature range: Component: –40°C to +85°C
Tape and reel packaging: –45°C to +80°C
7.Resistance to soldering heat: Three reflows at >217°C for 90 seconds
(+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room
temperature between.
8. Electrical specifications at 25°C.
See Color Coding section for part marking information.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
