These chokes are used mainly for RFI suppression of appliances and machines. Moreover these highly symmetrical chokes can be used as transformers as well as for potential separation.
Compared to common mode chokes on ferrite core (see our series 101 to 106 ), have these chokes at same dimensions and current rating up to three times higher inductance and they hereby achieve higher noise suppresion nearly in whole observed frequency range.
Our standard offer consists of double chokes PMEC 403, 404 and 406 series in vertical and horizontal design.
On request we can supply chokes with three or more windings too.
