Matters Needing Attention
- Chip resistors shall be stored in a room where temperature and humidity must be controlled (temperature 5 to 35, humidity 45 to 75% RH). However, humidity should be kept low if possible.
- Chip resistors shall be stored so direct sunlight doesnt hit them.
- Chip resistors shall be stored with no moisture, dust, materials that will make solder ability inferior, and harmful gases (Hydrogen chloride, sulfurous acid gas, and Hydrogen sulfide).
- Storage life: 1 year.
