Infrared 750nm LED High Power SMD LED

How do I know If my LED is IR? 

Since most of 2835 SMD LED looks like the same in the appearance. Size is the same, polarity the same and the LED chip is very small so that it looks like the same too. Then how can we know if we got a IR LED? 

Light it up? Yes. becuase IR LED will got a dimmer light then common green LED or red LED. 

People might think that how can we see the light cause most of the infared radiation are  invisible. In this case, our cell phone camera will help a lot. Put the camera on the LED and light it up. Then you can see the IR rays from your screen. 

However, if the IR LED that we had in hand is a high power IR LED. It won't be that much bother. Because we will still can see some dim red spot in the middle of SMD LED even is very dim. 

High power LED 2835 SMD LED Size: 

Electrical Parameters:

*Pulse forward current confition: Duty 1% and Pulse width=10us.

*Soldering confition: Soldering confition must be completed with 3 secongds at 260℃

*Luminous intensity is measured by ZWL600.

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

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.
