output power chokes C toroid styles document 139-1 specifications subject to change without notice. document 139-1 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 130c or higher. industry standard footprint. ul 1446 approved insulation system available. all plastic material ul94v-0. 1 1 1 schematic footprint l max w max 2 2 2 x y for mounting stability 4 4 24 0.120/0.180 3,05/4,57 h max dmt1 series current lead part inductance 1 rating dcr max h l w x y diameter number min (h) (a) (ohms) max max max 0.01/0,25 0.01/0,25 nom dmt1-180-1.5 180 1.5 0.29 1.1/27,9 1.3/33,0 0.7/17,8 0.80/20,3 0.40/10,2 0.054/1,37 dmt1-84-2.4 84 2.4 0.14 1.1/27,9 1.3/33,0 0.7/17,8 0.80/20,3 0.40/10,2 0.054/1,37 dmt1-43-3.8 43 3.8 0.07 1.1/27,9 1.3/33,0 0.7/17,8 0.80/20,3 0.40/10,2 0.054/1,37 dmt1-26-5.1 26 5.1 0.04 1.1/27,9 1.3/33,0 0.7/17,8 0.80/20,3 0.40/10,2 0.054/1,37 dmt1-16-6.7 16 6.7 0.02 1.1/27,9 1.3/33,0 0.7/17,8 0.80/20,3 0.40/10,2 0.054/1,37 dmt1-7-10 7 10.0 0.01 1.1/27,9 1.3/33,0 0.7/17,8 0.80/20,3 0.40/10,2 0.054/1,37 1. minimum inductance at rated current. tested at 15.75 khz, 10 gauss level. 2. operating temperature range ?40c to +85c. 3. electrical specifications at 25c.
