Selfs - Current--compensated Noise Suppression Chokes - FAMILLE 42U11V2



LINEAR VERSION Voltage 250 Vac
Current 0.18 to 1.1 A

These chokes are fitted with two high-permeability U9 cores (ferrite). They are mainly used in devices
equipped with switched-mode power supplies, and in filters designed to prevent both the spread of
parasitic noise within the device, and the effects of line noise on the device itself.
