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 environments are these resistors suitable for?
They are uniquely formulated to prevent silver sulfide occurrence and are highly recommended for automotive, industrial, and Power supply applications in sulfur environments.
How should I calculate the voltage rating?
The rated voltage (E) is calculated using the formula: E = P × R (Rated power multiplied by Nominal resistance).
Is derating necessary at higher temperatures?
Yes, if the ambient temperature exceeds 70°C, the power must be derated according to Figure 1.
Can these resistors handle pulsed loads or transients?
It is crucial to evaluate the component in its mounted state when used with transients like pulse loads (short-duration, high-level loads).
What is the maximum operating temperature range?
The specified operating temperature range for this product is from -55°C to +155°C.
