HANDLING RECOMMENDATIONS
BAR CODE PRODUCT LABEL (example only)
In order to achieve excellent lifetime, the package of these
UV-LEDs consists of a ceramic substrate in combination
with a UV stable silicone as lens material. Compared to
standard materials silicone is generally softer and it tends
more to attract dust:
A
N
B
• Minimize the level of dirt and dust particles in contact with
the LED
Part No: VLMU3500-385-120
C
• Small amounts of particles on the LEDs, although
noticeable from a cosmetic point of view, do not affect the
performance in terms of brightness, reliability and quality

• If cleaning is required, a short rinsing with isopropyl
alcohol, not longer than 15 seconds, is recommended. Do
not use ultrasonic cleaning, it may damage the LED
A. 2D barcode
B. Par No: Vishay part number
• Do not apply mechanical stress on the silicone lens
C. QTY: quantity
• Avoid any piercing of the silicone lens by sharp objects
D. SelCode: selection bin code
• It is recommended to use a suitable pick and place tool for
the removal of the LED from blister tape without applying
stress to the lens. The recess of the pick-up needle has to
be larger than the silicone lens
E. Country of origin
• For manual handling using tweezers make sure that the
LED will be touched carefully at the sidewall of the ceramic
substrate, but not at the silicone lens

RECOMMENDED METHOD OF STORAGE
ESD PRECAUTION
Dry box storage is recommended as soon as the aluminum
bag has been opened to prevent moisture absorption. The
following conditions should be observed, if dry boxes are
not available:
Proper storage and handling procedures should be followed
to prevent ESD damage to the devices especially when they
are removed from the antistatic shielding bag. Electrostatic
sensitive devices warning labels are on the packaging.
• Storage temperature 10 °C to 30 °C
• Storage humidity ≤ 60 % RH max.
After more than 1 year under these conditions moisture
content will be too high for reflow soldering.
In case of moisture absorption, the devices will recover to
the former condition by drying under the following condition:
VISHAY SEMICONDUCTORS STANDARD
BAR CODE LABELS
The Vishay Semiconductors standard bar code labels are
printed at final packing areas. The labels are on each
packing unit and contain Vishay Semiconductors specific
