Are These LXZ and KG Capacitors Fake?

I recently bought an LJM capacitance multiplier (power supply filter).

The 6800 uF 63V Nichicon KG have very messy printing/sleeves.

The United Chemi Con LXZ are a value that I can not find in the datasheet. 2700 uF 63V does not seem to exist.

Are these yet more fakes?

Found your first/second pictures -Aliexpress.com -China


Third picture supposed to be Nippon Chemi-con but I just don't like the definition of the writing on them .


Nichicon have offices all round the world but China is one main factory but Japan still produces them I was able to find the same first picture capacitors easily enough , if you are lucky its Japan but pictures show China .



It is not unusual for capacitors manufacturers to change their capacitor specifications regularly .

They could be genuine but left over from a custom-order. If they get an order for 10,000 in a value/size not normally made, they might run-off 10,000 plus a few extra just in case. When the excess is not needed it shows up in the kinds of places kit-makers buy parts.

It could be fake in the sense that it has nothing to do with that brand, but it can be a "good fake" which meets reasonable needs and serves you well.

And of course it could be crap that blows-up first try and leaves your dog hiding under the sofa.
