4 Digit 7 Segment Display Common Cathode for Digital Clock

Product details

Build your own digital clocks, timers, and counters with this 0.36-inch, 4-digit, red 7-segment LED display with a common cathode connection. Perfect for Arduino, Raspberry Pi, and other microcontroller-based DIY electronics projects, this display offers crisp, high-brightness red digits that stay clearly visible even at low drive currents — making it energy-efficient for battery-powered projects. A seven-segment display is a simple, low-cost alternative to complex dot-matrix displays for showing decimal numerals, and remains a go-to component for digital clocks, timers, counters, and numeric readouts in hobbyist and educational electronics. Overview Four-digit, 0.36" red LED display with common cathode wiring, standard 2.54mm pin pitch for easy breadboard and PCB use. Features 0.36" digit height 4-digit display 2.54mm pin pitch — breadboard and perfboard friendly High-brightness red LEDs Low power consumption Common cathode connection Specifications Parameter Value Reverse Voltage (Vr) 5V Reverse Leakage Current (Ir) 50µA Forward Current (If) 25mA Peak Forward Current (Ifp) 100mA Power Dissipation (P) 100mW per segment Operating Temperature -40°C to +80°C Storage Temperature -40°C to +85°C Lead Soldering Temperature 260°C Common Applications DIY digital clocks and alarm clocks Countdown timers and stopwatches Score counters and numeric display panels Arduino, Raspberry Pi, and other microcontroller projects Can be driven directly or via driver ICs (e.g., 74HC595, MAX7219) for reduced pin count Package Includes 1 × 4 Digit 7 Segment Display (0.36", Common Cathode)
