Introduce of U core

High Flux cores are composed of compacted 50% nickel and 50% iron alloy powder. The base material is similar to the regular nickel iron lamination in tape wound cores. High Flux cores have higher energy storage capabilities, and higher saturation flux density. Their saturation flux density is around 15,000 gauss (1500 MT), about the same as iron powder cores. High Flux cores offer slightly lower core loss than Sendust. However, High Flux's core loss is quite a bit higher than MPP cores. High Flux cores are most commonly used in application where the DC bias current is high. However, it is not as readily available as MPP or Sendust, and are limited in their permeability choices or size selections. The U core has low iron losses and large fill factor, and 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.

Application of U core

U cores are frequently used in output chokes, power input filters and transformers for switched-mode power supplies and HF florescent ballasts.
