Selfs - Current--compensated Noise Suppression Chokes - FAMILLE 42H17 - 42V20



CASE VERSION Voltage 250 Vac
Current 0.4 to 3.6 A

These chokes are fitted with high-permeability toroid core (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.
