DT1608C Series
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 tempera-
ture 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 new designs, consider the LPS4018 as an alter-
native 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.
