(3) Heat Generation
· 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 with a zipper.
· Storage Conditions
· If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage
· Nichia LED electrodes and leadframes are silver plated copper alloy. The silver surface may be
· Please avoid rapid transitions in ambient temperature, especially in high humidity environments where
· Thermal design of the end product is of paramount importance.
· The operating current should be decided after considering the ambient maximum temperature of LEDs.
There is a possibility that this can cause exfoliation of the contacts and damage to the optical
characteristics of the LEDs.

cause the LED to corrode, tarnish or discolor. This corrosion or discoloration might lower solderability
or might affect on optical characteristics.

of the LED when making the system design.
electric power is affected by the thermal resistance of the circuit board and density of LED placement
on the board, as well as other components. It is necessary to avoid intense heat generation and operate
within the maximum ratings given in this specification.
Before opening the package :
After opening the package :
The LEDs should be kept at 30°C or less and 90%RH or less. The LEDs should be used within a
year.
Baking treatment : more than 24 hours at 65 ± 5°C
