Before using components in circuits where they will be exposed to transients such as pulse loads (short–duration, high– level loads), be certain to evaluate the component in the mounted state. In addition, the reliability and performance of this component cannot be guaranteed if it is used with a steady state voltage that is greater than its rated voltage.

Frequently Asked Questions
What kind of equipment should not use these resistors?
They are not designed for systems requiring extremely high reliability, such as medical instruments or aerospace machinery.
How must the rated power change at elevated temperatures?
If ambient temperature exceeds 70°C, the power rating must be derated according to the provided power derating curve (Figure 1).
What are the suitable soldering conditions?
Soldering should occur at 235±5°C for a duration of 2.0±0.5s when using Rosin-Ethanol (25%WT).
Can these resistors handle transient voltage changes?
No, performance cannot be guaranteed if used with a steady state voltage that is greater than its rated voltage.
