common mode chokes

In fact, I do have a spanish to french translation to do and I guessed that "Choques en Modo común " was a litteral translation from "Common mode chokes"

Sorry but no more context.
In fact, I do hafe a spanish to french translation to do and I guesses that "Choques en Modo común " was a litteral translation from "Common mode chokes"
So all the context that I have is :

Choques saturables: proporcionan una alta impedancia para interferencias de conmutación Triac, y una baja impedancia para componentes de 50Hz.

Choques en Modo común para evitar Interferencias Electromagnéticas (EMI)
Para corriente alterna
Para fuentes de alimentación conmutadas

Thanks everybody ;-)

Pouvez-vous nous fournir plus de contexte ? Ce "choke", est-il requis pour éliminer les harmoniques ou de limiter le courant en court-circuit ? Où est-il logé sur la platine ? Entre quelles composantes ?

re: choke

Do be aware that an inductive component may be called a 'choke', without its necessarily fulfilling that specific function!

In more formal technical language, we might talk of an 'inductor' — this is simply a component whose principle characteristic is its inductance, but makes no reference as to its actual function. More simply, we often talk about a 'coil'.
A 'choke', however, properly speaking, is an inductor used for a specific purpose; sadly, though, in everyday parlance, the word 'choke' has become a generic term for many different kinds of inductor, not all used for that specific purpose.

So while 'bobine d'arrêt' is as you say the proper translation for 'choke', when it is being used as such, very often 'choke' simply means a 'self', as used in Kashew's reference, for example.

Your wider context may make it clear, but if in doubt, then 'self' is probably as good a bet as any — at worst, it won't be downright wrong ;-)
