Attenuation Frequency Characteristics (Typical example)
S8V-NFS203 S8V-NFS206
The above characteristics are data acquired by the following measurement circuits.
Note: The noise filter attenuation characteristics are measured under a constant I/O impedance of 50 Ω. When used attached to actual equipment,
the power line impedance varies depending on the wiring method. Therefore, attenuation characteristics may not match those listed in the
catalog.
Note: If using at an altitude of 2000 m to 3000 m, multiply the above
derating curve by 0.8 to reduce the load. (Does not apply for
face-up mounting)
