|---|---|
| Resistance tolerance | +1 % (E24, E96) or +5 % (E24) |
| Maximum dissipation at 70 °C | 0.6 W (R < 1 Ω) |
| Temperature coefficient | ≤ 425 ppm/°C |
| Maximum permissible voltage (DC or RMS) | 350 V (PRO1), 500 V (PRO2), 750 V (PRO3) |
| Climatic category (IEC 60068) | 55/155/56 |
| Applicable IEC standards | IEC 60115‑1, IEC 60115‑4 |
PRO2 resistors are rated for a maximum continuous voltage of 500 V (DC or RMS).
A 1 Ω resistor can dissipate up to 0.6 W at an ambient temperature of 70 °C.
The resistors comply with IEC 60115‑1 and IEC 60115‑4.
