IR 780nm LED Emitter 2835 SMD LED 90-degree

2835 SMD LED with 90 degree dome lens package:

When we package a 2835 SMD LED with a 780nm LED wavelength and a 90-degree angle, it means that the LED will emit light at a wavelength of 780nm and have a viewing angle of 90 degrees.

Electrical Optical Characteristics:

*Luminous Intensity is measured byZWL600.

*λD is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of device.

Size of 2835 SMD LED 90 degree:

*This package are also available in 2835 SMD LED with Red Smd Led, Green Smd LED, UV LED, Blue LED and IR 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.
