Choke

Choke

En electrónica, una bobina de choke (del inglés to choke, obstruir; en la literatura aparece a veces castellanizado como "choque") es un inductor diseñado para tener una reactancia muy grande a una frecuencia o rango de frecuencias determinadas. Una bobina de choke se usa, bien para impedir el paso de una parte de un circuito a otra de la corriente alterna, al mismo tiempo que se deja pasar la corriente continua, o bien para impedir el paso de corriente en modo común, mientras deja pasar la corriente en modo diferencial.

Las bobinas de choke a frecuencias altas suelen tener núcleo de ferrita.
