Tnisesm 6pcs Coil DPDT PCB Power Relay DC 9V 8 Pins Mini Power Relay

Great little relay at a great price. I purchased the 12vdc version and had no problem with it. The wiring diagram is on the relay so it's easy to wire, even without any documentation.Overall, it served my needs perfectly and I am very happy with my purchase...

These arrived on time and in good condition. As others mentioned, they're just loose in a plastic bag, and it would be better if they used a piece of foam or even cardboard to protect the pins. A few were a little bent, but easily straightened without break them. Lead spacing is standard so they fit solderless breadboard, vector board, stripboard. Contact resistance was 0.0 ohms. Coil current at 12Vdc was 16mA.

I bought a bunch for a project I was constructing. Then some failed after the trainer was moved. I thought maybe after some use the contacts where carbonized, though the use was far lower then spec'd. Took them apart and found that the top orange plastic casing was very soft. I was gluing the relays casing to frame with hot glue. Well the casing was metal and cooled fast. The pressure I applied was not hard, but it distorted the casing and pushed the non moving contacts together. The clearances between the casing and the contacts is almost nill, so the casing pushed in enough to permanently push the contacts together.

For my application, their drop time was too slow. Not a defect in the part, just not the right part for me. Pretty consistent pick voltage, an attribute I found variable with other relays. Important when you are using just an RC to build up to pick.

A tiny bit of largwr print documentation would have been nice; however, the pin connections can be read on bottom of relay in the right light. In any case, worked as advertised. Great value for my 3v projects

small and reliable so far.

Works as expected. Great value for the cost

Their cases, as others have noted, are fairly thin and not very sturdy. But as long as you mount them securely on a circuit board and don't put any outside pressure on them they work just fine.
