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.
• Industry standard footprint.
• UL1446 Class B (130°C) Insulation System (UL File E83628)
• All plastic material UL94V-0.
