CMT-8530S-SMT-TR

Same Sky (Formerly CUI Devices) · Buzzers · SMD, 8.5x8.5mm

CMT-8530S-SMT-TR from Same Sky (Formerly CUI Devices), in a SMD, 8.5x8.5mm. 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 + passive +POLARITY terminal (bottom-right in the p.2 PCB layout top view). Number by convention; Same Sky prints none.
2 - passive -POLARITY terminal (top-right in the p.2 PCB layout top view).
3 NC no_connect NC corner pad, bottom-left in the p.2 PCB layout top view (mechanical, solder only).
4 NC no_connect NC corner pad, top-left in the p.2 PCB layout top view (mechanical, solder only).

CAD (KiCad official)

  • Symbol: CMT-8530S-SMT-TR
  • Footprint: Adom_Gen:Same_Sky_Formerly_CUI_Devices__CMT-8530_c3e78c
  • 3D model: SMD, 8.5x8.5mm (KiCad packages3D, STEP)
  • 3D model files: cmt-8530s-smt-etched.step / cmt-8530s-smt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cmt-8530s-smt.step / cmt-8530s-smt.glb are the bare package body.

Provenance

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

  • Datasheet: Same Sky (Formerly CUI Devices) datasheet (4 pp, sha256 f8ed8cb7e7a4f0bf, retrieved 2026-11-10, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
