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
Can I use this component in life-critical systems like medical devices?
Consult a sales representative if the equipment requires extreme reliability or if malfunction could directly endanger human life.
Do I need to derate the power at high ambient temperatures?
Yes, when the ambient temperature exceeds 70°C, the rated power must be derated using the specified power derating curve (Figure 1).
What precautions should be taken regarding voltage spikes or transients?
You must evaluate the component in its mounted state if exposed to transients (like pulse loads), as performance cannot be guaranteed otherwise.
