Care Note for Storage
Store in a controlled environment (temperature 535, relative humidity 4575% RH). Avoid direct sunlight. Do not store in humid, dusty, or environments with harmful gases that degrade solderability (e.g., Hydrogen chloride, sulfurous acid gas, Hydrogen sulfide). Storage life: 1 year.
Care Note for Operating and Handling
Avoid exceeding rated power, as it may negatively impact performance and reliability. Handle with care using tweezers to prevent damage to the protective layer or resistance body. Do not touch the product with a soldering tip during manual installation.
