Frequently Asked Questions
How should I calculate the voltage rating for this resistor?
The voltage rating is calculated by E = P×R, but it must not exceed the limiting element voltage.
Is there a temperature limit for operation?
No, the operating temperature range is wide, spanning from -55°C to +155°C.
What precautions are needed when the ambient temperature goes over 70°C?
When the ambient temperature exceeds 70°C, the power must be derated according to the provided power derating curve.
What kind of soldering process is recommended?
Soldering conditions vary; for example, one typical condition requires a duration of immersion around 2.0±0.5s at 235±5°C.
