I agree with tomacorp, it has just happened to me with capacitor voltage rating, the total range is from 2.5 to 50000 volts. When I move the slider, the first step already takes me to about 600V. Really for hardcore HV guys
Sliders are nice, but they have these kind of problems. It also happens to octopart. A log scale would definitely be better, but I also think that having the ability to manually modify the min and max value would sometimes be more practical than a slider.
