Note 1: All temperatures refer to of the package,

measured on the package body surface.

Solder reflow

※ Due to “Lead Free” nature, Temperature

and Dwelling time for the soldering zone is

higher than those for Regular. This may

cause damage to other components.

1. Recommended max past thickness > 0.25mm.

2. Devices can be cleaned using standard

methods and aqueous solvent.

3. Rework use standard industry practices.

4. Storage Environment: < 30℃ / 60%RH

Caution:

1. If

reflow

temperatures

exceed

the

recommended profile, devices may not meet

the performance requirements.

2. Devices are not designed to be wave

soldered to the bottom side of the board.
