I received 50 TEA2025B amplifiers over the mail today. I ordered these IC’s about two weeks ago at Aliexpress.com. Aliexpress is an affiliate of Alibaba. I have never ordered components from Aliexpress before and I was curious to see how they would perform. Eager to get my hands on these OpAmps I quickly unpacked but was horrified with what I saw. All 50 IC’s were just thrown in a plastic bag and put in an envelop. The only thing protecting the IC was a small piece of bubble plastic wrapped around the plastic bag. No wonder that half of the IC damaged. Multiple pins on an IC were bended severely. I just wonder why the seller didn’t take the trouble to put the IC in a conductive foam which is common practice. I’m a very disappointed customer.

| 50 TEA2025B’s with plastic bag envelop. Why send it like this? |

| Close-up of the IC’s with multiple bended pins. No wonder if you send IC’s like this |

| Straighten the pins and put the IC’s in conductive foam. I’ll will test the IC’s later to asses the damage. |
Thanks for reading!

Aliexpress and DX have lots of counterfeit components. I have here ~40pcs of fake AMS1117 3.3V LDO's, that do show 3.3V over it but when a very small current is drawn it immediately makes a short, supplying the full voltage to your load. Tested several of them an all behaved like this. Authentic component from Farnell is working as expected, but I lost few expensive atXmega chips because of counterfeit LDO's.. Not buying discrete components from Ali/DX anymore.
Wouldn't surprise me if all the amplifiers are broken. I have yet to test them but this is probably the last time I'll buy components from Ali (although they did promise me my money back).
