SMT Power Inductors – DT1608 Series
The Coilcraft DT1608 Series represents the ultimate in
cost-effective, miniature power inductors. The DT 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 char-
acteristics, the DT1608 Series can be used as ultra high
L inductors at zero or low current.

1. Part number on reel label will have a suffix to indicate packaging: C = machine ready 7″ reel, B = partial reel, D = machine-ready 13″ 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 more detail.
4. Average maximum allowable current. DT Series inductors are designed for current spikes as high as 2 × the current rating.
5. Operating temperature range –40°C to +85°C.
6. Electrical specifications at 25°C.
