DESCRIPTION
The VLMW621. is one of the most robust and light
efficient LEDs in the market. The small size and wide
viewing angle make these LEDs a prime choice for
backlighting applications and front panel indicators,
especially where space is at a premium. Its ceramic
package makes it the ideal light source in applications
of high thermal considerations allowing the additional
current drive for a maximum light output while
maintaining a high service life of up to 50K h. The
reflector inside this package is filled with a mixture of
silicone and TAG phosphor. The TAG phosphor
converts the blue emission partially to yellow, which
mixes with the remaining blue to white.

Note:
Luminous intensity is tested at a current pulse duration of 25 ms and an accuracy of ± 11 %.
The above type numbers represent the order groups which include only a few brightness groups. Only one group will be shipped on each reel
(there will be no mixing of two groups on each reel).
In order to ensure availability, single brightness groups will not be orderable.
In a similar manner for colors where wavelength groups are measured and binned, each single wavelength group is packed in a single reel.
In order to ensure availability, single wavelength groups can not be ordered.
