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.
