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.
