*1 The value is specified under the condition that either color is lightened separately. When the both diodes are lightened simultaneously,
the power dissipation of each diode should be less than the half of the value specified in this table.
*2 Duty ratio=1/10, Pulse width=0.1ms
*3 For 3s or less at the temperature of hand soldering. Temperature of reflow soldering is shown on the below page.
