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) E= P×R P: Rated power (W) R: Nominal resistance (Ω) Limiting element voltage 150V

Frequently Asked Questions
What is the maximum rated voltage for the component?
The limiting element voltage is 150V, which determines the voltage rating calculation.
What should I do if the ambient temperature exceeds 70°C?
You must derate the power according to the power derating curve provided in Figure 1.
How does the component perform under high heat exposure?
It can withstand an endurance test at 155°C for 1,000h with no load.
Can I exceed the maximum rated voltage?
No, if the steady state voltage exceeds its rated voltage, reliability and performance cannot be guaranteed.
