Based on the dimensions of the relay JQC-3F, from mechanical drawing on its spec sheet, there's no possible way that the stated dimensions for the 1-channel device 1CH RF are correct, nor even close. The stated dimensions are 10 cm x 8 cm x 3 cm, but I don't see how it could be bigger than 5 cm x 3 cm x 2 cm.

Does anyone know the actual dimensions of the receiver, or better yet, of the enclosure it come with?

TIA,
MM

Well, now that I have one in hand, just in case anyone else wants to know:

Board dimensions: 5.1 cm x 3.4 cm x 1.6 cm
Box dimensions: 6.5 cm x 3.7 cm x 2.1 cm (not including 0.7 cm mount tabs on ends, total length 8.9 cm)

I probably ought to keep this to myself, but I can't decide which is more the shame: that the documentation is so inaccurate, or that the folks that run this forum would ignore such a simple/basic/vital question. If that info had been available I would've bought 5 - 10 units.

Unwillingness to invest in decent docs is costing you sales.

The receiver draws 9.4mA in stand-by, 39mA while the relay is energized. (Which makes sense, as the spec for the relay says its coil draws 0.36 watts, which works out to 30mA at 12V.)
