970nm IR LED SMT 2835 SMD LED Infrared

2835 SMD LED Package with 970nm LED Emitter;

High temperature will burn the SMD LED or through-hole LED Lamps when they working. LED will be killed or damaged if the heat cannot dispacthed on time when they working. In this case, we are not recommend people use the high operation current to Through-hole LED Lamps. Such as 1W High Power LED with 5mm throguh-hole LED package, the max operation current its 60mA. Contrary on that, 2835 SMD LED perectly work with 60mA. For IR LED with 2835 SMD LED, as long as the chip can handle the current, the SMD LED frame case will take that working current because there have a heat sink on the bottom for heat dispatched. In this 970nm LED, the max working current is 100mA and 2835 SMD LED case are totally find with it~

SMD LED Features:

Dimension: 2.8*3.5*0.7mm;

Wavelength: 970nm LED(±10nm);

Lens type: Clear epoxy;

High reliability and high radiation intersity;

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.
