Éliminer le bruit grâce aux perles de ferrite
Les perles de ferrite sont composées d’un cylindre creux ou d’une perle composée de ferrite et sont idéales pour éliminer les bruits EMI hautes fréquences pour toutes les conceptions de circuit. Elles sont largement utilisées dans les dispositifs électroniques communs, y compris les téléphones cellulaires, les ordinateurs de bureau et les ordinateurs portables, les tuners TV, les lecteurs audio, les lecteurs DVD et les consoles de jeu, afin d'éliminer les bruits des lignes électriques. Faites votre choix parmi une sélection exclusive de filtres à perles de ferrite de marque disponibles chez Future Electronics.
Ferrite Beads
What is a Ferrite Bead?
A ferrite bead, or ferrite choke, is a simple hollow cylinder or bead that is made of ferrite material and that is used in order to suppress or filter the amount of high frequency electromagnetic interference (EMI) noise found in electronic circuits. Ferrite is a black semi-magnetic substance that is shaped like a cylinder and that consists of iron oxide along with a mixture of other metals. Ferrites are encased in rubber or plastic material to protect and keep the ferrite bead in place.
Types of Ferrite Beads
There are several different kinds of ferrite beads. At Future Electronics we stock many of the most common types categorized by maximum DC resistance, case size / dimension, rated current, impedance, operating temperature range and packaging type. The parametric filters on our website can help refine your search results depending on the required specifications.
The most common sizes for impedance are 120 Ω, 220 Ω, 600 Ω and 1kΩ. We also carry ferrite beads with impedance up to 2.7 kΩ. The rated current can be between 0.2 mA and 4000 A, with most ferrite beads having a rated current of 200 mA or 500 mA.
