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)
