470nm LED with 5050 Blue Surface Mount LED Case;

Blue SMD LED and through-hole LED Lamps got a wide range in wavelength. 450nm LED, 460nm LED, 470nm LED or 480nm LED can all be named as blue LED. In 5050UBC47D612, we produce this 5050 Blue SMD LED with three chips of 470nm inside. Compare with 450nm or 460nm LED, 470nm wavelength will more close to green wavelength, which make this 470nm LED emits more brighter blue light than 450nm. And 450nm are kind of deep dark blue color. When you install this SMD LED to your circuit, it will show you the super bright blue lights. 

5050 SMD LED Dimension Parameters

         These SMD LED case are also available for  IR LED, UV LED, Blue SMD LED, Red SMD LED, Amber LED ect.

Handling Precautions:

Compare to epoxy encapsulant that is hard and brittle, silicone is softer and flexible Althouth its characteristiec significantly reduces thermal stress, it is more susceptible to damage by extemal mechanical force. As a result, special handling precautions need to be observed during assembly using silicone encapsulated Led products. Failure to comply might lead to damage and premature failure of the led

1. Handle the component along the side surfaces by using forceps or appropriate tools.

2, Do not directly touch or handle the silicone lens surface. It may damage the internal circuitry.

3, Do not stack together assembled PCBS containing exposed LEDs. Impact may scratch the silicone lens or damage the internal circuitry.

4, 4-A The inner diameter of the SMD pickup nozzle should not exceed the size of the LED to prevent air leaks;

    4-B A plible material is suggested for the nozzle tip to avoid acratching or damaging the LED surface during pickup.

    4-C The dimension of the component must be accurately programmed in the pick-and-place machine to insure precise pickup and avoid damage during production;

    4-D As silicone encapsulation is permeable to gases, some corrosive substances such as H2S might corrode silver plationg of leadframe. Special care should be taken if an LED with silicone encapsulation is to used near such substances. 

5, Please aviod continued exposure to the condensing moisture environment and keep the product away from repid transitions in ambiemt temperature.

6, Product in the original sealed package is recommended to be assembled within 24 hours of opening.
