NOTES

1.

90 degree pins are available for this series. Add “-F” to end of model number to indicate 90 degree pin package.

2.

Parallel line test method is adopted to test the ripple and noise. Contact factory for more details.

3.

See Fig. 1 for typical application circuit.

4.

See Fig. 2 for typical application circuit.

5.

This device compiles with part 15 of the FCC rules. Operation is subject to the following two conditions:

-This device may not cause harmful interference

-This device must accept any interference received, including interference that may cause undesired operation.

6.

If product is not operated within the required load range, the product performance cannot be guaranteed to comply with all parameters in the

datasheet.

7.

This is an open frame part. At least 10mm safety distance between primary and secondary external components of the module is needed to meet

the safety requirement.

8.

In order to increase the conversion efficiency of the input with light load in the design, the product will have audio noise when it is operating, but it

does not affect the product’s reliability and performance.

9.

Module requires dispensing fixed after assembled.

10. Customization services available

*Due to advances in technology, specifications subject to change without notice.
