Triple Digit 0.28inch White 7 Segment LED Display Common Cathode

DTriple Digit 0.28inch White 7-Segment LED Display (Common Cathode)

Product Overview
Introducing the Triple Digit 0.28inch White 7-Segment LED Display (Common Cathode)—a compact, high-reliability numeric display engineered for versatility across audio equipment, home appliances, and industrial indicators. With its 0.28inch digit size (ideal for space-constrained devices), bright white illumination, and robust common cathode configuration, this display delivers consistent readability even in bright ambient light—while maintaining low power consumption and an ultra-wide operating temperature range (-45°C to 80°C).
Compliant with RoHS/REACH standards and built to industrial specifications, it ensures stable performance in extreme environments (from cold storage to warm appliance interiors) and supports long-term use in daily-operated devices. Whether for temperature readouts, process indicators, or audio equipment statuses, this 3-digit display balances functionality, durability, and energy efficiency.

Key Features
1. Compact & Versatile Design
0.28inch Digit Size: Perfect for small electronics and space-limited panels (e.g., compact thermometers, mini audio amplifiers), without sacrificing readability.
Industrial Standard Form Factor: Aligns with universal PCB layouts, simplifying integration into existing product designs and automated assembly lines.
Common Cathode Configuration: Works seamlessly with standard driver ICs and microcontrollers (e.g., Arduino, PIC), reducing circuit design complexity for engineers.
2. Extreme Environment Reliability
Ultra-Wide Operating Temperature: Functions flawlessly from -45°C to 80°C, making it suitable for harsh conditions (e.g., outdoor temperature indicators, industrial freezers, warm appliance interiors).
Stable Performance: Resists voltage fluctuations and environmental stress, ensuring consistent light output and segment clarity over time.
Long Lifetime: High-quality LED chips and durable construction minimize replacement needs, even in 24/7 operation (e.g., process control monitors).
3. Superior Visibility & Efficiency
Bright White Illumination: High luminous intensity ensures clear readability in bright ambient light (e.g., living rooms, factory floors) without additional backlighting.
Even Light Distribution: Luminance is uniformly spread across each segment, eliminating dim spots or “hot zones” for crisp, professional numeric output.
Low Power & Low Current: Optimized electrical design reduces energy use, extending battery life for portable devices (e.g., handheld temperature meters) and lowering operational costs for fixed equipment.
4. Global Compliance & Safety
RoHS/REACH Compliant: Meets international environmental and safety standards, eliminating regulatory barriers for sales in Europe, North America, Asia, and beyond.
Non-Toxic Materials: Constructed with eco-friendly components, ensuring safety for both users and the environment.
