METHOD OF TAPING/POLARITY AND TAPE AND REEL
SMD LED (VLM.3-SERIES)
Vishays 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.
