DESCRIPTION

The VLMK33.. series is an advanced modification of
the Vishay VLMK33.. series. It is designed to incorpo­rate larger chips, therefore, capable of withstanding a
50 mA drive current.

The package of the VLMK33.. is the PLCC-2 (equiva­lent to a size B tantalum capacitor).

It consists of a lead frame which is embedded in a
white thermoplast. The reflector inside this package is
filled up with clear epoxy.

APPLICATIONS

• Interior and exterior lighting

• Indicator and backlighting purposes for audio,
video, LCDs, switches, symbols, illuminated adver­tising etc.

• Illumination purpose, alternative to incandescent
lamps

• Automotive qualified

• General use

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 be not 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 be not orderable.
