0.28 Inch SMD Single Digit LED Display / seven segment display
White SMD LED Displays
Features:
- 0.28″ (inch) digit height.
- Packaged in tape and reel for SMT manufacturing.
- Design flexibility (common cathode and anode).
- Categorized for luminous intensity.
- The thickness is thinness than tradition display.
- The product itself will remain within RoHS compliant Version.
Descriptions:
- The SMD type is much smaller than tradition type components, thus enable smaller board size, higher packing density, reduced storage space and finally smaller equipment to be obtained.
- These devices are made with white segments and gray surface.
Applications:
- Suitable for indoor use.
- Audio equipment.
- Set top box.
- Game machine.
- Channel indicator of TV.

Notes:
- Luminous Intensity Measurement allowance is ± 10%.
- θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
- It use many parameters that correspond to the CIE 1931 2°. X, Y, and Z are CIE 1931 2° values of Red, Green and Blue content of the measurement.
