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. |
