3030 Domed SMD LED An LED in a 3030 (3.0×3.0mm) package, designed as a SMD indicator LED with a forward voltage of 1.8~3.4V (depending on emission color) and 20mA-class drive. Supports fully automatic SMT assembly and reflow soldering. Factory-direct from Dongguan Hongcheng Optoelectronics Co., Ltd. (an international member of Guangyu Group with over 20 years of LED packaging experience), it uses Grade A chips and 99.99% pure gold wire bonding and is RoHS certified. Free samples and custom brightness binning, color-temperature binning and tape packaging are available. Download the datasheet PDF on this page for complete electrical parameters and mounting dimensions.
Q: Can mid-power LEDs such as 2835/3014 be connected directly to 220V?
A: No. These LEDs are low-voltage 2-3.4V devices and require a constant-current driver supply. We can provide driver matching advice and support for complete luminaire solutions.
Q: What placement-machine accuracy does this LED require?
A: This 3030 package (3.0×3.0mm) has relatively large pads. A standard high-speed placement machine is sufficient, with no special accuracy requirements. Lead-free reflow soldering is supported (peak ≤260℃/≤3s).
