Hi sec!

I have a capacitor marked like this:

o
1 0 5
ooo

105=10 00000 pF

What are the filled black dots above and below the numbers? I'd be
interested in the voltage rating. The case is a brownish red cuboid
with round edges, about 5*5*7 mm, radial. Polyester?

Bye, Bernhard

the dots leads to the negative terminal of a polirized capacitor 104 means 10 the four means multiplier of zero. You can tell by the actual size.
Ceramic dielectric cap color code ri=retma cc=ceramic cap 20=style csize=h=tollarence 10=significant figures 4=number of 0 k= tol of cap. There are so amy dif type of caps style type that it is beyond the scope to magnify this text.
