SMT Power Inductors–DT3316 Series
These magnetically shielded inductors are designed for
a wide variety of applications, including board mounted
DC-DC converters, miniature power supplies and volt-
age multiplying circuits. They function equally well in
filter and smoothing circuit applications.
The Coilcraft DT Series represents the ultimate in cost-
effective miniature power inductors. They are constructed
of materials specially developed for surface mount ap-
plications to ensure the best possible reliability and ease
of use and handling.

1. Inductance tested at 0.1 Vrms, 100 kHz, 0 Adc.
2. Measured at the rated current. Refer to L vs Current curves for more detail.
3. Average maximum allowable current. DT Series inductors are designed for current spikes as high as 2 × the current rating.
4. Operating temperature range –40°C to +85°C.
5. Electrical specifications at 25°C.
