If you watch youtube videos about switching power supply teardowns, like "diodegonewild" you'll see that no-name switching power supplies from China generally have fake electrolytic capacitors now a days. If your circuit needs a 400 V 5 uF cap, just desolder and peel off the label on literally "any" capacitor then put a shrink sleeve label saying 400V 5uF and call it good. If it handles 400V that's great for everyone, if it doesn't, then just blame the customer for misuse or make it too hard to return a $2 no-name phone charger. Put a well regarded label on the fake cap, I suspect China ships more caps with ChemiCon labels, than ChemiCon themselves actually manufacture, LOL.
- HeyLaughingBoy 4y agoI remember making someone on arduino.cc angry because I pointed out that it was very unlikely that Omron actually made the relays on their $6 relay "shield." Or, if they were genuine Omron relays, probably were pulled off other equipment. My first employer (early 90's) would buy large lots of "pulls" for a fraction of the price that Arrow, Future or Digi-Key charged for new components. I'm guessing those sources are still available, just not as widely publicized these days.
