940nm LED IR Dome Lens SMD LEDs 90-Degree

3528 SMD LED with Dome Lens 90 degree:

The infrared LED described here is a basic and straightforward device. It is designed to emit infrared light within the range of 940-950nm. This LED is commonly used in various applications such as remote control systems and touch-less object sensing.

To use this LED, it can be combined with any of our IR receivers, which are compatible with this type of LED. The forward voltage required for this LED to function is 1.5VDC, and the maximum forward current it can handle is 100mA. We packaged this 940nm LED with 2835 SMD LED, which make this IR LED have a better performance when it's work in a high operation current. Because there have a cooling pad on the bottom of this SMD LED. 

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.

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.
