Windings have a 1:1 ratio and can be connected in series or parallel to create a wide range of inductance combinations. The secondary winding could be used as a feedback winding in switched mode power supplies. 49100C XYYWW 12.00 (0.472) 2 1 3 4 Recommended Footprint Details 1.00 (0.039) 5.00 (0.197) 8.00 (0.315) Max.
