Round Type Through Hole 5mm yellow water clear LED with 8000~10000
mcd
Description:
LEDs are 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.
Water-clear LED lenses are composed of a transparent plastic. They
are a little brighter because the transparency of the lens does not
allow for absorption or dispersion of the light. This type of lens
is a light straightening lens, and is used in devices such as
flashlights or traffic lights.
Features:
• High luminous power
• Yellow color
• Bulk, available taped on reel
• ESD-withstand voltage: up to 4KV
• The product itself will remain within RoHS compliant version.

Notes:
During lead formation, the leads should be bent at a point at least
3mm from the base of the epoxy bulb.
Lead forming should be done before soldering.
Avoid stressing the LED package during leads forming. The stress to
the base may damage the LED’s characteristics or it may break the
LEDs.
Cut the LED leadframes at room temperature. Cutting the leadframes
at high temperatures may cause failure of the LEDs.
When mounting the LEDs onto a PCB, the PCB holes must be aligned
exactly with the lead position of the LED. If the LEDs are mounted
with stress at the leads, it causes deterioration of the epoxy
resin and this will degrade the LEDs.
