Translating from Japanese: residue in capacitor?

[hilman]

So, I have made an experiment of a low pass filter, and made a bode plot out of it. My experiment was done 100 percent in Japanese and this means I cannot understand completely the experiment I have done. So, there is a statement there saying the higher the frequency of the input voltage, the higher the '残留静容量' , which google translate as 'Residual static capacity' of the capacitor. I do not think this is the correct translation as I can't google it. So, what it is actually?

I would guess it is a "surface charge". But this term usually refers to batteries and super-capacitors - not common capacitors.
Also, this translates back and forth correctly for Chinese. So maybe its 99% Japanese and 1% Chinese.

I think it is referring to the residual inductance or the impedance due to the residual inductance.

Perhaps the higher the frequency, the more significant will be the effect of stray (residual/wiring) capacitance---a warning that the simulation of an ideal lumped element network will, at higher frequencies, become an increasingly inaccurate model of any real-world build.

Its a low pass so the higher the frequency the higher the "attenuation".

 

[NascentOxygen]

Its a low pass so the higher the frequency the higher the "attenuation".

If OP were to change the filter into a high-pass and run the simulation again, observed changes in the diagnostic could add support to your speculation.

I guess I have figured it out. I have asked my Japanese friend, and it turns out it is referring to 'Residual Impedance'. The Japanese terms I've shown to you guys is kinda like the other rare term of saying it in Japanese. And it should be as the frequency increases, the residual impedance of the capacitor will decrease. Thanks a lot for the answers guys!

yay LOL
