555 Timer Chip IC ne555 Pulse Generator DIP-8 Single Precision Timer (pack of 30pcs)

The media could not be loaded.  I went ahead and tested them with a circuit I built for another project, they operated as expected. My only concern is that when I separated them into groups, they didn't add up correctly as I am missing one, but mistakes happen. Overall, great product, will buy again!

Price is reasonable and it is working as it is suppose to do. My application did not require a high accuracy nor fast frequency. Therefore I am not sure how good they are, but it works for general purpose.I found some of the pins were bent because the ICs are in a small container without any protection. The plastic is also not like a ESD protection one.

Good value. They all come packed in a anti-static ziplock pouch...and a nice little plastic case. Made in China. I haven't tried/tested any of them yet.

Great electronic product

One was DOA ( verified with a know good chip. I tired two others and they worked fine.

GOOD SELLER. Product as described.

Excellent item. Exactly what I wanted

The 555 timers and thrown into little box all remedy around together. They are supposed to be a non conductive foam material so no scratches or malfunctioning happens when they are use. so I have no idea if the chips are going to be bad or good until I use them and I have to do send them back if they're bad.
