U core (iron core) is high flux core with low iron losses and large fill factor, which offers an economical core design with a nearly uniform cross-sectional area. The surfaces of U-shaped cores are treated with antirust material. We suggest the user to carefully store the untreated products to avoid moist and rain.
Applications: U cores are frequently used in output chokes, power input filters and transformers for switched-mode power supplies and HF florescent ballasts.
