I'm currently designing a PCB in Eagle to build my own Nixie Clock. I know kits exist but I'm trying to do this from the ground up to get the experience. Nixie Tubes require 180V and I'm trying to mimic and existing SMPS Circuit (the bottom of the page has a parts list) but this was designed years ago and a lot of the parts it used are no longer available.
For Example C1: TPSD107M035 it is 100uF with a voltage rating of 35V with a comment saying to use the lowest ESR available. I'm trying to use SMD packages and I'm having trouble finding the part in Eagle. Only a handful of parts have 100uF and 35V voltage rating but they don't list the package type so I don't know what to set it as. This capacitor seems like it would work as a replacement but I cannot find its package information and I don't know if just matching 100uF and the voltage rating is all I need to do.
Would a higher voltage rating work as well? I know there is also polarized vs non-polarized capacitors exist but does that make a difference in most application?
Appreciate the help!
