Product Description
WE-SL020 020 Side View White Backlight SMD LED
Factory Supply WE-SL020 020 White Side View SMD LED Backlight Chip with 120° Wide Viewing Angle and High Brightness White Side Emitting LED Diode for LCD Screen, Keyboard, and Instrument Backlight Applications
Product Overview
The WE-SL020 is a dedicated 020 side-emitting white backlight SMD LED, specifically engineered for thin backlight modules in small LCD screens, membrane keyboards, instrument panels, and wearable devices. It utilizes an InGaN white chip with high luminous efficiency and features a built-in professional light guide structure that delivers uniform, soft white side lighting without glare or dark spots. Standard gold-plated terminals with clear polarity markings ensure full compatibility with automated SMT mounting processes.
Core Advantages
- Professional 020 side backlight dedicated package with slim narrow outline, perfectly fitting ultra-thin backlight light guide slot designs
- InGaN white chip delivering ultra-high brightness up to 1400mcd with high luminous efficiency and energy savings
- 120° wide viewing angle with uniform side light output and consistent color coordinates (X0.275/Y0.255) for pure white light without color cast
- Stable forward voltage (Typ 3.4V / Max 4.2V @20mA) with low power consumption, compatible with small MCU and lithium battery control circuits
- Gold-plated solder pads with clear positive/negative polarity identification, supporting automatic SMT pick-and-place for high mass production efficiency
- Dimension tolerance ±0.1mm with standardized pad layout for convenient backlight PCB design
- Wide operating temperature range (-20℃ to +70℃) with anti-vibration and anti-impact properties, ensuring service life ≥50,000 hours
- Customizable color temperature, luminous intensity, lens structure, and anti-static vacuum packaging options available
