General Notes

1.260℃ welding temperature, the whole process should not exceed 10 seconds, 350℃, the welding process should not exceed 5 seconds, otherwise it may cause damage to the product.
2. Make sure the wiring is correct, otherwise the product will be damaged.
3. The recommended mounting torque for base connection is 0.5N · m.
4. When the ambient temperature of the product is high, please refer to the temperature curve for derating.
5. The capacitive load will generate extremely high inrush current at the moment of re-conduction, which may lead to the damage of solid relay due to excessive inrush current. Therefore, if the load time capacity load or the load has parallel capacitor, it is strongly recommended to series NTC in the load loop to suppress the inrush current so as not to damage the product.
