Thank you all for the information and links! I did pickup some 1/4 watt chokes in preparation to work on passenger cars.
John, do those isolated converters work even if the input voltage is below the higher ratings specified, as I see most say input of 50v-250v
This one appears to work down to 55VAC. I bought these for a power line project, so no worries about that, I'll have 120VAC to drive them. I just wanted 5VDC from the power line in a small package, that was the object of the exercise.
