1. When welding, the distance between the welding point and the root of the resistor should be at least 6mm, the welding temperature should be below 350 ° C, and the welding time should be as short as possible
2. When cutting the product leads to the required length, pay attention to lengths>8mm
3. When bending the lead wire, the bending point should be at least 2mm away from the end of the sloping shell to avoid damage to the glass shell
4. Storage temperature:- 10°C~40°C
5. Storage humidity:< 75%RH
6. Avoid storing in environments with corrosive gases and light exposure.
7. After opening the packaging, it needs to be resealed and stored
