P. 4/9

Part Number: XZMDH160S

3.45X3.45mm SMD LED WITH CERAMIC SUB-

STRATE

Heat Generation:

1.Thermal design of the end product is of paramount importance. Please consider the heat generation of the LED when making the system design.

The coefficient of temperature increase per input 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.

2.Please determine the operating current with consideration of the ambient temperature local to the LED and refer to the plot of Permissible

Forward current vs. Ambient temperature on CHARACTERISTICS in this specification. Please Also take meas ures to remove heat from the area

near the LED to improve the operational characteristics on the LED.
