I need a 1.85K resistor for my stepper and G540 combo. The closest I can find is a 2k. Besides using a G540 EZ how would you solve this problem? Does wattage matter also?
as the Gecko spec is 1/4W 5% (1k per amp upto 3.5 A max)
you could use a 1.82K or 1.87K 1/4W 1% metal film resistor
and still be within 1.85K + or - 5%
PS have a look at Digikey.com 1.87K 1/w 1% part number 1.87KXBK-ND

while the maximum current is 3.5A without a current set resistor
I would use a 3.48K 1% resistor so the output current is reduced in standby
