Ordering and Inquiry Information
SMD models use tape-and-reel packaging (quantity per reel is subject to the corresponding datasheet), with minimum orders in full reels. Sample lead time is typically 3-4 working days; volume production lead time is typically 10-15 working days (subject to order confirmation). For volume pricing, use the inquiry link on this page or phone/WeChat 139 2571 4318. Specify the exact part number and quantity.
Selection Recommendations
Forward voltage varies considerably by color/model (commonly 1.8~3.4V). Calculate current-limiting resistors using the VF range in the selected model's datasheet, and set the reflow profile according to the corresponding datasheet.
