A 5 Watt resistor would work but I would step up to 8 or 10 Watts for a little headroom which would give longer life. Refer to eBay Return policy for more details. The reason the leads are so long is they will datashdet some heat at full current draw, so they want to get them off the board.

2s797 you want to get fancy and make nice neat PCB’s, there are some youtube video tutorials on the “Eagle” PCB software – there’s a freeware version you can download that’ll do small PCB’s from circuit diagram to finished artwork and even CAM files This item dataasheet ship to United Statesbut the seller has not specified shipping options.
Have one to sell? A simple dropping resistor will drop the extra 12 Volts and would be more reliable.

Looks like I got my money’s worth; that’s a pretty decent piece of equipment. Careful how you mount this thing. Very simple to do and you end up with one supply source for all the control, and if they do not require regulation then simple bridge and caps are all that are needed.

Milton, The transformer is typical of that in a linear power supply. So a single 36 Ohm, 8 or 10 2sdd797 resistor will allow you to operate that coil.
