Note:

1. If the product is not operated within the required load range, the product

performance cannot be guaranteed to comply with all parameters in the

datasheet;

2. The maximum capacitive load offered were tested at nominal input voltage

and full load;

3. Unless otherwise specified, parameters in this datasheet were measured under

the conditions of Ta = 25°C, humidity <75% with nominal input voltage and

rated output load;

4. All index testing methods are based on our Company’s corporate standards;

5. We can provide product customization service;

6. Specifications are subject to change without prior notice.
