METHOD OF TAPING / POLARITY AND TAPE AND REEL
SMD LED (VLM.3 - SERIES)
Vishay’s LEDs in SMD packages are available in an
antistatic 8 mm blister tape (in accordance with
DIN IEC 40 (CO) 564) for automatic component insertion.
The blister tape is a plastic strip with impressed component
cavities, covered by a top tape.
