Acid Etched Components

The chip was acid etched so you can't find it. There is no information on the packaging. As an electrical engineer, I don't like not having specs, but at least I can look up the specs of any chip on cheap Chinese circuit boards. I might even return it. It's all about having PCBs ready for projects. If I can't specify it, I can't use it.

Pros
  • Adopts 4mΞ© ultra-low internal resistance MOS tube, which features low internal resistance and high efficiency. It is suitable for battery packs in various fields such as inverters, DC motors, power tools and solar street lights.
Cons
  • Good but not great
