Selfs - Current--compensated Noise Suppression Chokes - FAMILLE 42H27 - 42V30
| CASE VERSION | Voltage 250 Vac Current 0.5 to 4 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
