U Cores

U Cores

U Cores are used for higher power operation when there are fewer spaces or unusual form factors. They have long legs which is why they offer the advantage of low leakage inductance and promote superior voltage isolation. The cores are available in different sizes such as UU1928, UU2036, UU2840, UU3544, UU3562, UU5756, and UU5972. Common applications for U cores include power transformers.
