10. Designing precautions
(1) The current limiting resistor should be placed in the circuit so that is driven within its
rating. Also avoid reverse voltage (over-current) applied instantaneously when ON or OFF.
(2) When pulse driving current is applied, average current consumption should be within the
rating. Also avoid reverse voltage applied when put off.
(3) Recommended soldering pattern
<For reflow soldering>
Unit : mm
The above dimensions are not the one which guarantee the performance of mount ability.
The use of the above pattern is recommended to use after deep study at your site.
(4) When assembling the circuit board into the finished products, care must be taken to avoid
the component parts from touching other parts.
(5) When using multiple LEDs, it is required to connect a current limiting resistor on
each path which the current flows to the LEDs.
