The Kingbright SA52-11EWA is a single-digit numeric LED display with seven segments and a right-hand decimal point. It uses a common-anode configuration and high-efficiency red LEDs manufactured using GaAsP/GaP technology.
The digit height is 13.2 mm (0.52 inch). The package has a grey face, white segments and a white diffused lens. It is designed for through-hole mounting (THT) on a printed circuit board or socket and has ten leads on a 2.54 mm pitch.
It is suitable for numeric and status indication, time displays, domestic appliances, electronic equipment, instrumentation and industrial applications. The drive circuit must provide appropriate current limiting; when LEDs are connected in parallel, each LED must have its own current-limiting resistor. The device should also be protected against reverse voltages and transient voltage spikes.
Through-hole displays in this series are not compatible with reflow soldering. For wave soldering, Kingbright specifies a peak temperature of 245–255 °C for 3 s, with a maximum of 5 s, and no more than one pass. Prolonged reverse bias should also be avoided.
