7.Drive circuit

- A constant current circuit is recommended as a drive circuit.

And when two or more LED packages are connected, the series connection

between each package is recommended.

- Please design a circuit that prevents any reverse voltage (excess current) from being

applied to this product instantaneously when the circuit is ON or OFF.

- As this product is designed with consideration of the heat release property of module,

- Factors responsible for an increase in temperature include heat generation attributed to

ambient temperature conditions or power dissipation. Thus, drive conditions should be

taken into consideration, depending on ambient temperature (Ta).

- Soldering operation should be performed within 3.5 seconds per land using a soldering iron

- This product is intended for the application in general electronic devices (such as

- Our warranty does not cover situations where this product undergoes secondary

fabrication such as changes in shape.
