Review on 6Pcs DPDT Mini Power Relay HK19F-8P-12V, 8 Pin PCB Relay With Coil For DC 12V Applications by Dino Burks

Revainrating 1 out of 5

It does work on 3 volts. See serious update!

UPDATE; 2-11-23; Down to 1-STAR! All finished and all leads soldered, and I moved a wire going to a coil pin….AND IT SNAPPED OFF AT THE BASE! The original bent leads were more serious than I thought! Also, please note my experience to evaluate and work with this simple part: I worked as a mil-spec and NASA Certified Solderer/engineer. Also 65 years as a build-your-own stuff ham radio operator. END OF UPDATE. It draws about 65 milliamps (0.065 amps) at 3 volts, and the coil is 47 +- Ohms. They (6) came in a bubble-only envelope with most of the relay pins mashed over, due to no protective packaging, but did straighten out if bent back carefully. Hence only a 3-star rating.My anxiety and frustration over this is because it’s going into a hand engraved talking musical jewelry box for my wife for Valentine’s Day…in 3 days. It worked perfect, until I had to do ‘just more thing’…move that wire! I’ve worked on this since December! FYI; The music is ‘You Are My Sunshine’…and she has been for 59 years.

Pros
  • Awesome
Cons
  • The relay's small size may make it difficult to handle, increasing the risk of damage during transportation or installation
