This document describes a 3.5x2.8mm surface-mount chip LED lamp with super bright yellow color. It is suitable for all SMT assembly and solder processes, and ideal for backlighting. The LED has a white SMD package with low thermal resistance.
The Kingbright KA-3529SYS-L is a 3.5 × 2.8 mm SMD chip LED in a silicone resin package, designed for backlighting and SMT assembly. The datasheet provides detailed electrical and optical characteristics, absolute maximum ratings, and package information such as a 1500 pcs/reel tape and Level 4 moisture sensitivity.
Handling precautions emphasize careful side‑surface handling, avoiding contact with the silicone lens, and proper nozzle sizing for pick‑and‑place. A reflow soldering profile for lead‑free processes is also included, recommending a peak temperature of 245 °C (±5 °C) and limiting the number of reflow cycles to two.
