Points For Attention
- Optimal shelf life: within 180 days from ex-factory date.
- Seal unused products with sealing tape to prevent solder pad oxidation.
- Avoid contact with water, sweat, or dust on solder pads. Do not touch solder pads with bare hands.
- Product performance may vary with operating conditions; re-test for different applications.
- Exceeding voltage, current, or temperature limits can cause irreversible damage and functional degradation.
- This product is not suitable for humid, dark, or strongly corrosive environments.
