| Maximum overload voltage |  |  |  | 100 | V | Overload test voltage = specified magnification × RCWV, or maximum overload voltage, whichever is less | 2 |
| Resistance tolerance |  | -0.5 |  | 0.5 | % | Tolerance code D = ±0.5 % (ERJ 1R, 2R, 3R, 6R series) | 1 |
| Temperature coefficient of resistance (T.C.R.) | TCR | -50 |  | 50 | ×10-6/K | Code H = ±50 × 10-6/K (1R, 2R series) | 1 |

## CAD (KiCad official)

- Symbol: `ERJ2RHD1001X`
- Footprint: `Resistor_SMD:R_0402_1005Metric`
- 3D model: 0402 (KiCad packages3D, STEP)
- 3D model files: `erj2rhd1001x-etched.step` / `erj2rhd1001x-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `erj2rhd1001x.step` / `erj2rhd1001x.glb` are the bare package body.
