Nichia is one of the largest LED manufacturers in the world and inventor of the blue (and thus also white) light emitting diode. The innovative Nichia research department is a pioneer when it comes to efficiency and establishes records on a regular basis.

The Nichia SMD LEDs in the range UV light can be used for a wide range of applications. The NCSU276A is available with three different wave lengths. At 365nm wavelength the Nichia LED reaches a power of 780mW.This UV LED is only suitable for use in industrial applications.

Warning:

invisible light, the LED constitutes a danger for the eye even at short-term radiation. Please consult our employees for advice on this product before ordering!

This LED is designed to be reflow soldered to a PCB. If dip soldered or hand soldered, Nichia will not guarantee its reliability.

• Reflow soldering must not be performed more than twice.
• When cooling the LEDs from the peak temperature a gradual cooling slope is recommended; do not cool the LEDs rapidly.
• During reflow soldering, the heat and atmosphere in the reflow oven may cause the optical characteristics to degrade. In particular,
  reflow soldering performed with an air atmosphere may have a greater negative effect on the optical characteristics than if a
  nitrogen atmosphere is used; Nichia recommends using a nitrogen reflow atmosphere.
• This LED uses a silicone resin for the lens and internal pre-coating resin; the silicone resin is soft. If pressure is applied to the lens,
  it may cause the lens to be damaged, chipped, and/or delaminated. If the resin is damaged, chipped, delaminated and/or
  deformed, it may cause the wire to break causing a catastrophic failure (i.e. the LED not to illuminate) and/or reliability issues
  (e.g. the LED to corrode, the radiant flux to decrease, the color/directivity to change, etc.). Ensure that pressure is not applied to the lens.
  If an automatic pick and place machine is used for the LEDs, use a pick up nozzle that does not affect the lens.
  Recommended conditions:
  Using a nozzle specifically designed for the LEDs is recommended (See the nozzle drawing below).
• Ensure that the nozzle does not come in contact with the lens when it picks up an LED. If this occurs, it may cause internal disconnection causing the LED not to illuminate
