Selfs - Current--compensated Noise Suppression Chokes - FAMILLE 42U15V 4A 42U15V 4B
| LINEAR VERSION | Voltage 250 Vac Current 0.35 to 1.45 A |
These chokes are fitted with two high-permeability cores (ferrite) U15 type. Each winding is split in two
sections to reduce the winding capacitance. They are mainly used in devices equipped with switchedmode
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.
