I use them in 1.25A and 1.75A , but can't remember my source . The only place I could find fast ( 45 minutes ) is here , Not an exact match , but 2 amps ought to work just fine IMO .

I love those buggers , use them often . Not sure if they are ok for house juice , I only use them for secondary LV power of 24 volts or less . Easy to put on DIP's , SIP's , and Perf boards .
