Title: How much current each FPC connector can handle?
Post by: ali_asadzadeh on May 28, 2020, 07:00:02 am

Hi,
I have a product that needs 5V @1.2A and I should use these FPC connectors and Flat cables to power them, I just wonder how much current each pin can carry?

Any Ideas or experience?

You can find FPC connectors rated for about half an amp per pin but i never felt comfortable with that.

But something like 250mA per pin sounds about reasonable to me and is commonly used for powering LCD backlights from such 0.5mm pitch FPC strips.

So yeah for 1.2A you will need quite a few pins.
