Product Description
9.91mm 0.39 Inch 1 Digit 7 Segment LED Screen Through Hole DIP Numeric Tube
0.39 Inch 1-Digit 7-Segment LED Display Tube | Common Cathode / Common Anode High Visibility Mini Numeric Indicator
Product Overview
This 0.39-inch single-digit 7-segment LED numeric tube features high-efficiency light-emitting chips with uniform luminosity and includes an independent decimal point for flexible decimal value display. It supports both common cathode and common anode polarity options, with standard through-hole DIP pins for easy soldering and stable mechanical fixation. Compared with smaller 0.28/0.32/0.36-inch single-digit models, it offers enhanced digit visibility while maintaining a compact PCB footprint, making it ideal for portable measuring equipment, small household appliances, low-power IoT modules, and battery-powered consumer electronics.
