VLMW21..
For technical support, please contact: LED@vishay.com
Note:
1) Driving the LED in reverse direction is suitable for short term application
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, single wavelength groups will be shipped on
any one reel.
In order to ensure availability, single wavelength groups will not be
orderable.
