Precaution of Application
Designing 1: Soldering pattern
The dimensions of the recommended soldering pattern may not meet every user. Please
confirm and study first before designing the soldering pattern in order to obtain the best
performance of soldering.
Designing 2: Circuit layout
Due to the circuit design is not available, assuming the circuit is in parallel and a resistor that is
put in series in the circuit, it cannot provide an effective current-limiting function to the LEDs
due to each LED had a different inherent resistance. In general, the LEDs usually have a
different inherent resistance. Different inherent resistance will cause different current, the LED
on the different path would be driven at different power, and the result was the LED with a
higher resistance would be dimmer than the other. To solve this situation, a suitable resistor is
put in series with each LED to limit the current disparity through the LED will be very useful.
Designing 3: Max Rating
Any application should refer to the specifications of absolute maximum ratings.
Dry Pack
Any SMD optical device, like this chip LED, is MOISTURE SENSITIVE device. Avoid
absorbing moisture at any time during transportation or storage. Every reel will be packaged in
the moisture barrier anti-static bag (Specific bag material will depend upon customers’
requirement or option). And the bag is well sealed before shipment. By customer’s requirement,
we will put a humidity indicator in each moisture barrier anti-static bag before shipment.
