Revised 12/05/02
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 H 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.
