Suggestion with DC Power jacks
-
Hi all,
I am designing a board and felt I would take your suggestions. The board I'm designing will be driving 8 seperate board that has 14 WS2812b RGB LED's on each board. So totally the controller board will drive 14x8 = 112 WS2812b LED's.
I've learnt from online sources that approximately these ws2812b led will draw 50mA at max. So by calculating the max current drawn is 5.6A and I also have an ESP32 with some other normal peripherals. So rounding it I thought of using a DC power jack that can tolerate 6A and supply voltage would be 12V.
Can anyone suggest me any plugs or jacks that are widely used and easy for integration? Help would be much appreciated.

What about JST Connectors?
-
@salmanfaris Does JST have such high power connectors?? It shouldn't be something like header connections. I need it to be like DC barrel connector kind of connectors. And that connector must not heat up even at 6A

Thes pins can handle 6A or more and easy to use and available local shops.
-
@salmanfaris yeah I've got suggestions like these from people but I'm making more professional product which will be implemented at offices and public places. So I need more like DC barrel plug in kind of thing.
-
How many connectors/terminal do you need? how frequently you need to disconnect and connect plug?
-
@salmanfaris I would need any connector like a barrel jack. The mating cycle per month is very low, something like 2 times it might be removed and connected. These devices will be powered on most time of the day.
-
@kowshik1729 Then go with a standard barrel jack, it can handle 6A.
