Caution
Plastic components, due to their water absorption characteristics, should be protected from environments with temperatures higher than 30 and humidity above 60% RH after the package is opened. Ensure all components are used within 24 hours of opening to prevent foaming or deformation during reflow or wave soldering processes.
