DT1608 Series
The Coilcraft DT1608 Series represents the ultimate in
cost-effective, miniaturepowerinductors. TheDTSeriesis
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.
For free evaluation samples or to order, contact Coilcraft

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.
