Binocular Cores

Binocular Cores

Ferrite binocular cores are wonderful for making many different ratios of voltage baluns/ununs and magnetic baluns for balanced loads. Typical ranges of ratios are 1:1 to 16:1. Our 9:1 beverage transformer uses the BLN-68-61 core featured below. Shown in the picture below is a 1:1 current balun made with a BLN-61-61.
