Document 139-1 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 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. Industry standard footprint.
