PCB Mount Current Transformer
PCB Mount Current Transformer

PCB mount current transformers are very suitable in many circumstances, as they can be easily assembled on the print circuit board without the extra wire connecting. Xianyu provides 2-pin or 4-pin mini current transformer with a standard pitch, which is very convenient for customers. The mount mehod is up-right, which makes the profile very small and occupy little space of the PCB. As high permeability nanocrystalline or amorphous core are adopted, the linearity of final CT is excellent and phase error is very low.
