450Nm LED Chip with 5050 SMD LED PLCC6;

450nm LED and 470nm LED are all blue LED, even you can also name 480nm LED as blue LED. Compare with these wavelength, 450nm will be close to purple color and 470nm and 480nm will be more close to green wavelength. So 450nm LED are kind of like blue plus purple, which is deep blue with a little purplish. And 480nm color will be like blue plus green, then the color will like light blue with greenish. In 5050UBC45D6L18, there have three 450nm LED chip inside 5050 SMD LED case. You will got a uniform blue color when you light three of chip up and it will emits bigger lighing spot than 2835 SMD LED. And this SMD LED are dimmable, when you turn down the current that can reduce the bbrightness and when you increase the operation current brightness will brighter.

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.
