LTC-3822YCA2 Yellow 4 Digit Common Anode 7-Segment Display Module

From the shop's description

LTC-3822YCA2 Yellow 4 Digit Common Anode 7-Segment Display Module The LTC-3822YCA2 Yellow 4 Digit Common Anode 7-Segment Display Module is an industrial-grade, 0.28-inch (7.0 mm) quadruple-digit yellow LED display module into a robust 30-contact edge-connector PCB format. Operating as a Common Anode device, it requires a positive supply voltage to be switched across its four digit-enable pins (Anodes) while the individual segment shapes (A-G), decimal points, and specialized colon indicators are activated by pulling their corresponding cathode pins to ground through current-limiting resistors. Its GaAsP/GaP construction provides a high-intensity 585 nm yellow output designed for visibility in professional test equipment and industrial panels, offering significantly better mechanical stability and corrosion resistance via its copper-plated contact pads compared to the standard through-hole DIP packages found in basic consumer electronics. Features 0.28-Inch Digit Height: A compact “low profile” character size ( 7.0 mm) that allows for high-density information display in small handheld or rack-mounted devices. Yellow GaAsP/GaP Technology: Uses Gallium Arsenide Phosphide on Gallium Phosphide. This provides a crisp yellow output ( 585 nm) which offers better visibility in high-ambient light environments compared to standard red LEDs. Multiplexed Internal Wiring: To reduce the pin count, the segments (A-G) of all four digits are connected in parallel. This requires “time-division multiplexing” to display different numbers on each digit. Common Anode Logic: The anodes of all segments within a single digit are tied together. This makes the module compatible with standard “sink-type” driver ICs (like the ULN2803 or 74HC595). Industrial Carrier PCB: Unlike standard 16-pin DIP (Dual In-line Package) LEDs that plug into sockets, this “YCA2” version is mounted on a rigid FR-4 PCB with Copper-plated pads for long-term corrosion resistance. Integrated Colon/Indicators: Features additional LEDs between the second and third digits, making it ideal for clock (HH:MM) or ratio displays.
