High Current Chokes

EPCOS offers its High Current Choke series, designed to solve core material saturation problems

Image of Epcos' High Current ChokesCompact electrical and electronic equipment primarily generates common-mode interference.  In order to meet the safety requirements (keeping within the leakage current limits), chokes with a high asymmetrically effective inductance must be used. Current compensated chokes with a closed core topology are especially suitable for this purpose.

The problem of core material saturation due to the useful current is solved in these designs by winding two coils with equal number of turns on the core. These coils are connected in such a way that the magnetic flux induced by the upper coil is compensated by the lower coil.

EPCOS' High Current Chokes are available in vertical or horizontal versions.
