ACSA04-41 optoelectronic Series
kingbright0.4-inch single - digit surface - mount LED displays
The ACSA04-41 optoelectronic series from Kingbright is a compact surface-mount LED display designed for single-digit applications. These displays measure 0.4 inches in diameter, making them ideal for space-constrained environments where a simple numeric readout is needed. If you're working on projects that require small, discrete digital indicators, these displays are a solid choice.
One thing worth noting is their robustness; they are built to withstand harsh conditions, which makes them suitable for industrial settings or outdoor use. Engineers tend to reach for this when they need a reliable, low-profile display option without the complexity of multi-digit modules. Another practical advantage is their low profile, which allows them to fit neatly into tight spaces while still providing clear visibility of the digits. Their surface-mount design simplifies PCB assembly and integration, making them a preferred option for many circuit boards.
