Chokes by Flux

Chokes are a type of inductor used in electrical circuits to block (“choke”) high-frequency alternating currents and to allow direct current (DC) and alternating currents of lower frequencies to pass. Chokes also reduce ripple currents in power supplies. 


Chokes manufactured by us are typically used in power supplies for EV Charging, eMobility systems, audio systems, and in advanced electronics for satellites, spacecraft, airplanes, and rocket boosters.

In such applications, standard chokes are not applicable, as all these applications require extensive testing and quality assurance on a higher scale.

Flux choke types

Output chokes

Output chokes dampen ripple currents in power supply outputs.

ChokesFlexcards - Output choke

Differential mode chokes

Differential mode chokes are used to reduce differential noise on either side of the power supply.

ChokesFlexicards - differential mode choke

Common mode chokes

Common mode chokes are used to reduce common-mode noise on either side of the power.
