- Within the temperature range of 55 to +85 °C, the rated voltage is equal to the maximum continuous voltage.
- Between + 85 and + 125 °C the maximum continuous voltage must be reduced linearly from the full rated voltage to 2/3 of it (derating).
- At 150 °C (only B4519*P series) the voltage must be reduced to 1/2 and at 175 °C (only B4519*T series) to 1/3 of the rated voltage.
- All unfavorable operating conditions (such as possible line overvoltages, unfavorable tolerances of the transformation ratio of the line transformer in the equipment, repeated overvoltages when the equipment is switched on, high ambient te.

Engineering review checklist
- Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
- Derate continuous power for ambient temperature and verify pulse or surge capability separately.
- Match the land pattern, termination finish and current-sense routing to the exact package option.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
