Precautions for Use

Maintain ambient temperature below 40 and humidity below 70% to prevent solderability degradation.
Minimize opening of minimum packaging.
Reduce specified power usage according to the derating curve in high-temperature environments.
Avoid connecting multiple resistors in parallel or series for high voltage or current applications.
Handle with care to avoid collisions with the resistor body, as the incombustible coating is less resistant to external shocks.
After cleaning, allow resistors to dry naturally for 20 minutes before contact or painting to restore film strength.
Ensure adequate heat dissipation by avoiding dense arrangement of resistors or proximity to other heat-generating components; use cooling devices if necessary.
