Rated voltage The voltage rating is calculated by the following equation. If the value obtained exceeds the limiting element voltage, the voltage rating is equal to the maximum operating voltage.
E: Rated voltage (V) P: Rated power (W)
Limiting element voltage 150V

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 is the primary benefit of the TRR10 series resistors?
They feature unique protective materials preventing silver sulfide formation, making them ideal for sulfur environments.
How should I calculate the voltage rating before use?
The formula is E=P×R. If this value exceeds the limiting element voltage (150V), use 150V as the rating.
Does power exceedance require derating?
Yes, if ambient temperature exceeds 70°C, the power must be derated according to Figure 1.
What types of equipment are these resistors NOT suitable for?
They are not designed for use in equipment that requires an extremely high level of reliability, such as life-support medical instruments or aerospace machinery.
