CDRH129RNP-330MC

Sumida · Power Inductors · SMD, 12x12mm

CDRH129RNP-330MC from Sumida, in a SMD, 12x12mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). The symbol is generated from that pin table and the footprint is an Adom_Gen land derived from the manufacturer drawing; the 3D model is generated to fit it.

Pinout

Pin Name Type Function
1 1 passive One terminal of the 33µH ±20% inductor (100kHz), with 39.3 mΩ max DCR, 4.00 A saturation current and 4.25 A temperature rise current.
2 2 passive Other terminal of the 33µH ±20% inductor (100kHz), with 39.3 mΩ max DCR, 4.00 A saturation current and 4.25 A temperature rise current.

CAD (Adom-generated)

  • Symbol: CDRH129RNP-330MC
  • Footprint: Adom_Gen:Sumida_CDRH129
  • 3D model: generated to fit the land (STEP)
  • 3D model files: cdrh129rnp-330mc-etched.step / cdrh129rnp-330mc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cdrh129rnp-330mc.step / cdrh129rnp-330mc.glb are the bare package body.

Provenance

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

  • Datasheet: Sumida datasheet (4 pp, sha256 7fbceb7ac1d3e185, retrieved 2026-10-15, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: symbol generated from the datasheet pin table; footprint an Adom_Gen land derived from the manufacturer drawing. 3D model generated to fit that land.
