Odd... So I ordered some "#Bourns" multiturn precision #potentiometers from an #AliExpress seller, both linear, but two different values.
They were #cheap, so you expect them to be #fake. Real Bourns stuff isn't cheap.
But as far as I can tell, the 10kΩ ones are fake, but the 100kΩ ones I received appear to be the #real thing. Now, they could be "3rd shift" or factory floor sweepings... but they're marked #Mexico. Seller is in China.
