4-Digit Amber LED Clock
0.4" Common Anode
Amber 7-Segment Display
4-Digit 7-Segment LED
LED Clock Amber Anode
Product Overview
This 0.4-inch (10.16mm) 4-digit 7-segment LED display is engineered for versatile multi-digit numeric readouts in set-top boxes, home appliances, and instrument panels. With compact outer dimensions (40.5×16×7mm) and a high-contrast design—white segments on a black surface—it delivers clear visibility while supporting dual polarity (Common Cathode/CC + Common Anode/CA) to eliminate circuit compatibility barriers. Available in 6 vibrant emission colors (red, blue, green, amber, orange, white), it balances high luminous intensity and efficiency with low power consumption and extremely low current, ensuring stable performance and long lifespan for daily use. RoHS compliant, IC compatible, and easy to assemble, it's a cost-effective solution for devices requiring reliable 4-digit displays.
Key Features
1. Dual Polarity Flexibility (CC/CA)
Supports both common cathode and common anode circuits, adapting to diverse PCB designs without requiring hardware modifications. This eliminates the need to source separate display models for different projects—ideal for manufacturers with mixed product lines (e.g., set-top boxes and home appliances using different circuit configurations).
2. Compact 4-Digit Layout & Optimal Readability
0.4-Inch Digit Height: 10.16mm characters strike a balance between readability and space efficiency, fitting seamlessly into slim device enclosures (e.g., compact set-top boxes, small kitchen appliances like rice cookers).
4-Digit Capacity: Enables display of multi-digit values critical for target applications—such as set-top box channel numbers (e.g., "1234"), home appliance timers (e.g., "05:30"), or instrument panel metrics (e.g., "250V").
3. High Contrast & Uniform Illumination
White Segments on Black Surface: Minimizes glare and maximizes digit sharpness, ensuring clear readability in bright (e.g., kitchen countertop) or dim (e.g., living room) environments.
Even Luminous Distribution: Light spreads consistently across all segments of the 4 digits, eliminating uneven glow or dark spots—critical for quick, accurate readings of timers, channels, or status values.
4. Energy Efficiency & Durability
Low Power Consumption: Extremely low current reduces energy usage, making it suitable for 24/7 operated devices (e.g., set-top boxes in standby mode) or battery-powered digital indicators.
Stable Long-Term Performance: Robust construction ensures resistance to wear from frequent use, paired with a long lifespan to minimize maintenance or replacement costs for appliances and electronics.
5. Easy Integration & Compliance
IC Compatible: Works seamlessly with standard display driver ICs, simplifying circuit design and reducing development time for manufacturers.
Hassle-Free Assembly: Compact 40.5×16×7mm size and standardized pin layout enable easy mounting on PCBs, streamlining production processes.
RoHS Compliant: Meets global environmental standards, ensuring safety for household use and compliance with international regulations (e.g., EU CE, US FCC).
