CG0402MLU-3.3G

BOURNS · Varistors · 0402

CG0402MLU-3.3G from BOURNS, in a 0402. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A passive Terminal 1 of the bidirectional ESD protector. Connect between the signal line and ground (device is symmetric/bidirectional, so terminal assignment is interchangeable). Clamps transients above ~250 V trigger to protect downstream circuitry.
2 B passive Terminal 2 of the bidirectional ESD protector. Connect between the signal line and ground (device is symmetric/bidirectional, so terminal assignment is interchangeable). Clamps transients above ~250 V trigger to protect downstream circuitry.

CAD (KiCad official)

  • Symbol: CG0402MLU-3.3G
  • Footprint: Resistor_SMD:R_0402_1005Metric
  • 3D model: 0402 (KiCad packages3D, STEP)
  • 3D model files: cg0402mlu-3-3g-etched.step / cg0402mlu-3-3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cg0402mlu-3-3g.step / cg0402mlu-3-3g.glb are the bare package body.

Provenance

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

  • Datasheet: BOURNS datasheet (4 pp, sha256 f29173b512250d11, retrieved 2026-08-17, 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).
