ECE2EM2R2E12OTPO

Yunxing · Aluminum Electrolytic Capacitors - Leaded · CP_Radial_D6.3mm_P2.50mm

ECE2EM2R2E12OTPO from Yunxing, in a CP_Radial_D6.3mm_P2.50mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1 passive Terminal 1 of a POLARISED capacitor (Capacitors / Aluminum Electrolytic Capacitors - Leaded). Which terminal is the anode (+) is not yet recorded on this page: read it from the maker's datasheet before placing.
2 2 passive Terminal 2 of a POLARISED capacitor (Capacitors / Aluminum Electrolytic Capacitors - Leaded). Which terminal is the anode (+) is not yet recorded on this page: read it from the maker's datasheet before placing.

CAD (KiCad official)

  • Symbol: ECE2EM2R2E12OTPO
  • Footprint: Capacitor_THT:CP_Radial_D6.3mm_P2.50mm
  • 3D model: CP_Radial_D6.3mm_P2.50mm (KiCad packages3D, STEP)
  • 3D model files: ece2em2r2e12otpo-etched.step / ece2em2r2e12otpo-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ece2em2r2e12otpo.step / ece2em2r2e12otpo.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Yunxing datasheet (10 pp, sha256 3744bc4a8faeafd0, retrieved 2026-11-06, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary two-terminal convention (convention), consensus off (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
