CAD (KiCad official)

  • Symbol: T491D107K010AT
  • Footprint: Capacitor_Tantalum_SMD:CP_EIA-7343-31_Kemet-D
  • 3D model: CASE-D-7343-31(mm) (KiCad packages3D, STEP)
  • 3D model files: t491d107k010at-etched.step / t491d107k010at-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); t491d107k010at.step / t491d107k010at.glb are the bare package body.
