Selfs - Current--compensated Noise Suppression Chokes - FAMILLE 42H14
| Case version | Voltage 250 Vac . Current 0.3 to 2 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.
