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.
