Date: 2026-07-21 Official datasheet found and set on the part project:
Set the Datasheet URL to the official Maxwell PDF and completed the part review in BCAP0360 P270 S18 Part Review.
Key flags: metadata is broadly correct, but the symbol is under-specified—no polarity, no pin descriptions, and all four terminals are Unspecified; the two blank mechanical terminals must be clearly isolated/NC per datasheet. The footprint body diameter looks plausible, but pad polarity mapping and drill/hole geometry need verification before publishing or ordering.
Fix the symbol so it clearly labels positive, negative, and the two isolated mechanical terminals.
I’ll update the four terminal definitions so the symbol explicitly shows +, −, and two isolated mechanical/NC support terminals, then verify the properties.
Updated and verified the symbol terminal properties:
  • Pin 1: Positive terminal (+), Passive
  • Pin 3: Negative terminal (-), Passive
  • Pins 2 and 4: Isolated mechanical support terminal - do not connect, Not Connected
Open item: the footprint pad-to-datasheet mechanical mapping and drill size still need separate verification if you want this part fully publish-ready.
