Round Type High Brightness 5mm Green Water Clear LED With
20000~30000 mcd
Description:
LED is a semiconductor light source that emits light when current
flows through it. It is available in a range of colours - red,
green, orange, yellow, blue and even white. There are even more
exotic colours such as turquoise, violet and ultra-violet but they
are considerably more expensive than common reds & greens.
The housing of the LED is made from an epoxy resin. Whilst it has
to be translucent to allow the light out, there are different types
of translucency available. The most common is "diffuse" - this is
the same colour as the device and looks cloudy, to help diffuse the
light evenly from the speck of semiconductor (which would only be
about 1mm square) into the top portion of the housing.
Features:
• High luminous power
• Green color
• Bulk, available taped on reel
• ESD-withstand voltage: up to 4KV
• The product itself will remain within RoHS compliant version.

Storage:
• The LEDs should be stored at 30°C or less and 70%RH or less after
being shipped from Xinghui and the storage life limits are 3
months. If the LEDs are stored for 3 months or more, they can be
stored for a year in a sealed container with a nitrogen atmosphere
and moisture absorbent material.
• Please avoid rapid transitions in ambient temperature, especially,
in high humidity environments where condensation can occur.
