UYF CORES
Introduce UYF cores
UYF core is one of Mn-Zn ferrite core, has round leg, which allows easy winding, also of strip conductors.
Because of the high voltages involved, the round shape helps to prevent corona effect. U-type cores are used
for power, pulse and high-voltage transformers, and UYF cores are special cores, similarly possess of the same
use. UYF core, with the U-Shape core's thickness C (sometimes also including U core height 2 x B) as its
distinction, consists of 10~18 series, some gets two round cylinder surfaces, some only gets one. The series of
UYF cores are abundance, including UYF16, UYF15, UYF17, UYF18, UYF14, UYF13, UYF12, UYF11.5, UYF10,
UYF9.8, UYF9.6, UYF11.5, UYF14.5, UYF14.7,etc. The same type of UYF16, UYF15, UYF17, and others also has
different specifications, please find the details in the follow tables.
Features UYF cores:
1. High Saturation Magnetic Flux Density (Bs)
2. Low Core Loss
Application of UYF cores:
1. Transformer for Power Supply
2. Fly Back Transformer for TV set And Monitor
3. FBT and kinds of transformers
