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.

Core Product Advantages
  • Upgraded Visibility & Compact Size Balance: Larger digit size than 0.36-inch single-digit tubes, providing clearer reading under bright ambient light without occupying extra PCB space.
  • Uniform High Brightness Output: Premium LED chips eliminate uneven dark/bright segments, maintaining consistent luminous performance for long-term continuous operation.
  • Dual Polarity Compatibility: Two polarity versions match diverse MCU drive circuit designs, reducing secondary hardware development costs for engineers.
  • Mass Production Friendly Assembly: Standard through-hole pin layout adapts to automated wave soldering processes, boosting factory production efficiency.
  • Industrial-Grade Wide Temperature Resistance: Stable luminous performance under extreme cold and heat, applicable to industrial handheld devices and semi-outdoor portable equipment.
  • Optimized Low Power Consumption: Balanced brightness and power loss design, perfectly suited for rechargeable battery-powered portable products.
Main Application Scenarios
  • Portable digital multimeters, handheld field measuring testers
  • Mini household appliances: humidifiers, portable chargers, coffee makers, compact timers
  • Wearable smart gadgets & low-power IoT sensor terminal indicators
  • Power banks, lithium battery chargers, voltage/current monitoring displays
  • DIY embedded development boards & student electronic experiment kits
  • Automotive miniature status indicators & vehicle auxiliary control panels
