RL2512JK-070R47L from YAGEO, in a 2512. 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 | One of two matte-tin (Ni/matte tin) end terminations of the 0.47 Ω low-ohmic thick-film chip resistor (RL2512: 1 W at 70 °C, ±5%), non-polarized and interchangeable with the other terminal. |
| 2 | 2 | passive | The other matte-tin (Ni/matte tin) end termination of the 0.47 Ω chip resistor (RL2512: 1 W at 70 °C, ±5%), non-polarized and interchangeable with the other terminal. |
