METHOD OF TAPING / POLARITY AND TAPE AND REEL
SMD LED (VLM3-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.
