(2) Storage
(1) Moisture Proof Package
· When moisture is absorbed into the SMT package it may vaporize and expand during soldering.
· The moisture proof package is made of an aluminum moisture proof bag.
· Storage Conditions
· If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage
· This product has silver plated metal parts that are inside and/or outside the package body.
· After assembly and during use, silver plating can be affected by the corrosive gases emitted by
· Please avoid rapid transitions in ambient temperature, especially in high humidity environments where
There is a possibility that this can cause exfoliation of the contacts and damage to the optical
characteristics of the LEDs.

The silica gel changes its color from blue to pink as it absorbs moisture.

Any LED with tarnished leads may lead to poor solderability and deterioration of optical characteristics.
Please do not expose the LEDs to corrosive atmosphere during storage.
