The document describes the features and characteristics of Agilent's 8mm (0.31 inch) ultra mini seven segment displays. These displays have high light output, high peak current, and are excellent for long digit string multiplexing. They are compact in size with 8mm character height and a wide range of color options. The displays have a gray/black surface for optimum contrast and evenly lighted segments with mitered corners. They have a ± 50° viewing angle and can be configured as either common anode or common cathode, with a right hand decimal point. The displays are commonly used in appliances, temperature controllers, and digital panel meters.
This datasheet provides technical specifications for the HDSP-U Series of 8 mm (0.31 inch) Ultra Mini Seven Segment Displays manufactured by Agilent Technologies. These devices are designed as space-efficient character displays suitable for viewing distances up to 3 metres, featuring options for Common Anode or Common Cathode configurations and a wide range of colors including Red, Orange/Yellow, and Green.
The document details the part numbering system, package dimensions, internal circuit diagrams, and absolute maximum ratings. It includes specific electrical and optical characteristics such as luminous intensity, forward voltage, and peak wavelength for each color series (AlGaAs Red, High Efficiency Red, HER/Orange, Yellow, and High Performance Green). Additionally, it provides graphical data on current vs. temperature derating and efficiency curves.
