Selfs - Current--compensated Noise Suppression Chokes - FAMILLE 42U11V4
| LINEAR VERSION | Voltage 250 Vac Current 0.3 to 2 A |
These chokes are fitted with two high-permeability U11 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.
