Output Power Chokes – Toroid Styles
The DMT power inductors are designed primarily for
use as output chokes in switching power supplies. The
toroid core design offers the highest inductance values
in the smallest part size, while minimizing external
magnetic fields.
Inductance values range from 7 µH to over 1.4 mH with
current ratings as high as 12 Amps.
These parts are ideal for any application requiring a
high DC current bias. They are well suited for use in
switch-mode power supplies and can be used as ripple
filters and differential mode EMI filters.
• All insulating materials 130°C or higher.
• Industry standard footprint.
• UL 1446 approved Insulation System available.
• All plastic material UL94V-0.
