Matters Needing Attention
- Chip resistor shall be stored in a room where temperature and humidity must be controlled (temperature 5 to 35, humidity 45 to 75% RH). However, keep humidity as low as possible.
- Chip resistor shall be stored away from direct sunlight.
- Chip resistor 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.
