U, I, UR Cores U CORES U shape cores are ideal for higher power operation in tight spaces or unusual form factors. The long legs of a U core support low leakage inductance designs and facilitate superior voltage isolation. U/I combinations facilitate economical assembly. U cores are ideal for power transformer applications.
