Points For Attention
- Best shelf life: within 180 days from ex-factory date.
- Seal remaining unused products with tape to prevent pad oxidation.
- Avoid contact with moisture, sweat, or dust on pads.
- Re-test if using in different applications due to changing working conditions.
- Exceeding voltage, current, or temperature limits can cause irreversible damage.
- Not suitable for humid, dark, or strongly corrosive environments.
