Russian language capacitor abbreviation

Looking at several Russian websites selling Russian aluminum electrolytic capacitors with colored pictures and sizes the MKF stands for MFD--IE-- 22MKF-47MKF-50MKF- so Micro-farad.

The company selling them as I look at the website is in the Moscow area and on checking with the apps I have added to my browsers its definitely Russian not elsewhere.

They are not NOS nor is China,s --Alibaba involved .
