Application Notes
These resistors are intended for general electronic applications. For specific environmental conditions or specialized applications, please consult RALEC for confirmation of suitability and performance. Customers should evaluate and confirm product characteristics in their actual application conditions, ensuring fail-safe design for system safety. Handle with care to avoid mechanical stress and damage.
Storage and Handling Conditions
- Storage environment: 255, 6015% RH for up to two years.
- Avoid harsh environments such as sea breeze, corrosive gases (Cl2, H2S, NH3, SO2, NO2), direct sunlight, and condensation.
- Ensure correct box orientation during handling and storage; avoid dropping or crushing to prevent damage to electrodes or the body.
