SB Series toroidal cores
SB series toroidal cores are developed to satisfy the customers who are eager to minimize their cost, which are wound by a continous silicon steels strip, occasioinally with joints.
The appearance of the SB cores are very similar to traditional toroidal cores. Material thickness 0.20mm, 0.23mm, 0.27mm, 0.30mm and 0.35mm are available.
The stacking factor is ranging from 0.94 to 0.96. The magnetic properties of SB series cores are very close to that of A series cores, the Bm values are relatively lower because it is recycle material.
Dimensions:
Minimum strip width: 10mm
Maximum strip width:250mm
Minimum inside diameter: 20mm
Maximum outside diameter:1200mm
Application
Toroidal cores are used in instrument transformers power transformers inductor transducers and variable transformers.
