0.1uF

Hi,

I have already downloaded this but I didn't find this information. As far I can understand from the datasheet it depends on the distance between the two leads to compute the right capacity, Am i wrong? What page to look in this datasheet?

It's the μ1 on the second line on the top, page 2 of the pdf explains it (but a bit hidden).
Not the most obvious marking I agree...

Why don't they CLEARLY mark its capacitance LIKE EVERY OTHER CAPACITOR MANUFACTURER??

So the μ1 = 0,1μF on the top of the capacitor or it means 1μF?

The example inside the datasheet as far as I can understand relates the capacitance with the space of the leads? And where the heck it says that 1μ = 0.1μF ?

u1 is not 1u. u1 = 0.1 uF, 1u = 1uF

They won't describe such simple things you should already know in the datasheet.

Yes, of course, I knew that BUT I thought that it was an internal marking code (I didn't really realize at the begging that this symbol was actually a "u") so my question, in this case, is where should I find a table that this symbol corresponds to a capacitance number!

Now it's all clear. Thank you!
