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 voltage multiplying circuits. They function equally well in
filter and smoothing circuit applications.
The Coilcraft DT Series represents the ultimate in costeffective miniature power inductors. They are constructed
of materials specially developed for surface mount applications to ensure the best possible reliability and ease
of use and handling.

1. Part number on reel label may have a B suffix to indicate that the reel is not machine ready.
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.
