Part Verification and Datasheet Update

flux

I’ll review the part metadata and existing symbol/footprint, find the official datasheet if missing, update the Datasheet property if needed, then verify pins and summarize any mismatches.

Completed the part review and added the official Murata datasheet URL to the part terminals. Full findings are in Part Verification Report: DE1E3RA102MJ4BH01F.
Key issue flagged: the symbol is acceptable for a non-polarized 2-pin capacitor, but the footprint pads do not match the datasheet — expected 10.0 mm lead spacing and through-hole pads for 0.6 mm leads; current pad geometry appears near-zero spacing and far too small.

Provide a concise direct to the point best description for this part based from the datasheet. i don't need a very long but useless description.

Project symbol review
  • Symbol contains two terminal components with Pin Number 1 and Pin Number 2.
  • Pin type is currently Unspecified for both terminals.
  • For a non-polarized capacitor, two generic passive terminals are acceptable; there is no polarity or functional pin naming required.
  • The schematic currently shows no nets, which is acceptable for a standalone part definition.
Project footprint review
  • Footprint contains two pads, but computed pad positions are approximately x=0 mm and x=0.01 mm, giving only ~0.01 mm spacing.
  • Datasheet lead spacing is 10.0 mm, so the footprint pad spacing does not match the datasheet.
  • Pad sizes are computed as ~0.0013 mm, far too small for 0.6 mm diameter through-hole leads.
  • Pad hole type appears to fall back to default SMD rules unless overridden; this part requires through-hole pads suitable for 0.6 mm leads.
  • Silkscreen/body outline appears roughly 7.0 mm x 4.0 mm in the visible drawing, consistent with the datasheet body dimensions, but the pad geometry is not consistent.
Datasheet property update
  • Added the official Murata datasheet URL to both terminal components' Datasheet URL property.
Mismatches / issues flagged
  1. Footprint pad spacing mismatch: expected 10.0 mm, found ~0.01 mm.
  2. Footprint pad size mismatch: expected practical through-hole annular pads for 0.6 mm leads, found ~0.0013 mm computed size.
  3. Footprint pad type mismatch/risk: part is radial through-hole; pad rules appear not explicitly configured as through-hole.
  4. Pin descriptions are not explicit beyond pin numbers; acceptable for a non-polarized capacitor, but could be improved by setting both descriptions to Terminal or Capacitor terminal.
  • Set pad centers to 0 mm and 10.0 mm spacing, or symmetrically to -5.0 mm and +5.0 mm.
  • Configure pads as plated through-hole with hole size around 0.8 mm to 0.9 mm for 0.6 mm leads, subject to fabrication tolerance preference.
  • Use pad diameter around 1.6 mm to 2.0 mm for adequate annular ring.
  • Keep the body/silkscreen outline at approximately 7.0 mm x 4.0 mm centered between the leads.
