Infrared 850nm IR LED 90-Degree 2835 SMD LED

There are three kinds of 850nm LED chip that we can package this 2835 SMD LED dome lens package: common type, high bright type and super bright type. Today we discussed about the common type of IR LED in 850nm wavelength. 850nm LED chip that can be packaged in the 2835 SMD LED dome lens package. The common type of 850nm LED chip is a standard option that provides a moderate level of brightness. It is suitable for various applications where a basic level of infrared illumination is required. This type of LED chip is commonly used in remote controls, security systems, and infrared communication devices. The common type of 850nm LED chip offers a good balance between performance and cost-effectiveness. It typically has a lower power consumption compared to the high bright and super bright types, making it suitable for applications where energy efficiency is important. However, it is important to note that the common type of 850nm LED chip may not provide the highest level of brightness compared to the other types. If a higher level of infrared illumination is needed, the high bright or super bright types may be more suitable options. Overall, the common type of 850nm LED chip packaged in the 2835 SMD LED dome lens package is a reliable choice for various applications that require infrared illumination at a moderate brightness level.

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.
