UF&UI CORES
Features of UF core, UI core and UU core
UF core, UI core and UU core, these Soft ferrite shapes are available in lamination materials (for stacking),
powdered material (typically powdered iron), and ferrite materials. In laminated form, their features are similar
to that of the “C” core, and can take full advantage of grain orientation while their laminated counterparts only
take about 60% to 80%. UF core, UI core and UU core the heat dissipation is excellent and there is lots of room
available for lead wires, but self-shielding is poor. UF core, UI core, UU core and other “U” cores have two core
legs. Coils can be placed over either or both legs. Using coils on separate legs is great for high voltage isolation
between coils. The mean turn length of two coils on separate legs (sharing the whole winding window) is smaller
than 1 coil on one leg (occupying the whole winding window), hence the two coils connected in series has less
winding resistance. “U” type cores, such as UF core, UI core and UU core may be used for “split-core” current
transformers. And the series of U-type cores including UI8.5, UF9.8, UF10.5, UF15, UF12, UF16, UF19, UF25.4,
UF30, UF33, etc.
Application of UF core, UI core and UU core:
U-type cores are mainly used for power, pulse and high-voltage transformers, flyback transformers in B/W and
color TV sets.
UF core: mainly used for line filters in color TV sets;
UI core: Line filters, Inverter transformers;
UU core: Line filter transformers, Common mode choke, TV flyback transformers.
