I was looking this datasheet:
https://www.tme.eu/en/Document/8c1ff45156797735249e0c74a685b1eb/SR_PASSIVES-3305SMD.pdf . It doesn't contain parasitic capacitance of the trimpot, so I wanted to google it separately. Guess what happened when I tried to copy part number (3305SMD): I got "RKT-C3305", which is made by Kingtronics. When I googled it I got exact same datasheet, but different header:
http://www.kingtronics.com/pdf/RKT-c3305.pdf . Turns out it's the same datasheet, just SRPassives put their logo and header on top of existing (see attached picture for exact location of hidden text).
Moreover, I can't really find any info about SRPassives. What looked like a proper vendor name is just a rebadge (they don't even have a website). That feels deceptive to me, even thought most (if not all) distributors do this ((in)famouse Farnell's multicomp, for example).
Don't know why I'm so surprised, but I decided to share my findings with you guys
