Description

0.36 Inch 4-Digit Common Cathode Red 7-Segment Display

The 0.36 Inch 4-Digit Common Cathode Red 7-Segment Display is a compact, high-visibility module for numeric indication in electronic circuits. With bright red LED segments and a 0.36-inch digit height, it provides clear readability while saving panel space. The common cathode configuration interfaces easily with popular driver ICs and microcontrollers, supporting multiplexed operation in both prototypes and production builds.

Built for reliability and low power consumption, it’s ideal for timers, counters, clocks, and measurement panels. A standardized pin layout simplifies wiring and PCB design, while the durable package suits compact enclosures.
