0.4-Inch (10.16mm) Triple-Digit 7-Segment LED Display – Super Bright Red, Common Cathode for Audio & Home Appliances
Product Overview This triple-digit 7-segment LED display is engineered for high-visibility, energy-efficient numeric readouts across consumer and industrial devices—featuring a 0.4-inch (10.16mm) character height, compact outer dimensions (30.1×16×7mm), and vivid super bright red emission. Configured as common cathode for seamless circuit integration, it stands out with a durable "yellow epoxy + black surface" design that enhances contrast and resists wear. Optimized for performance, it delivers high luminous intensity via tailored forward voltage, while boasting low power consumption, extremely low current, and even segment luminosity—ensuring reliability in bright ambient light (kitchen countertops, audio racks). Fully RoHS/REACH compliant and compatible with industrial standard sizes, it supports 6 additional emission colors (blue, green, white, amber, orange, yellow) and adapts to diverse use cases: from audio equipment to temperature/humidity indicators. Its slim 7mm depth fits tight enclosures, making it a versatile solution for precision-focused numeric display needs.

Core Product Features 1. Super Bright Red Visibility & Contrast Super bright red emission: The red is highly visible in both dim (audio equipment racks, basement instrument panels) and bright (kitchen countertops, retail displays) environments—without the harsh glare of white LEDs. Its high luminous intensity ensures digits (0-9, plus decimal points for precision) stand out at a glance, making it ideal for: Audio equipment: Volume levels or channel gains viewed in dimly lit studios. Home appliances: Microwave timers or refrigerator temperatures in sunlit kitchens. Yellow epoxy + black surface: The bold contrast eliminates ambient light reflection and enhances digit clarity—critical for precision indicators like temperature monitors or process gauges , where misreading a value could lead to errors. The yellow epoxy also adds durability, resisting scratches from daily use . 2. Energy Efficiency & Thermal Stability Low power consumption + extremely low current: Minimizes energy draw, offering dual benefits: Battery-powered devices: Portable thermometers, handheld humidity meters, or wireless process sensors (extends battery life by 30-40% vs. higher-current displays). 24/7 operated equipment: Audio amplifiers, home appliance control panels (e.g., electric water heaters), or industrial process monitors (reduces long-term electricity costs and heat generation). Optimized forward voltage: Delivers maximum luminous intensity without wasting power—ensures bright, consistent digits without straining circuits or shortening LED lifespan. 3. Industrial-Grade Reliability & Integration Evenly distributed luminosity: Light spreads uniformly across all 3 digits and segments, eliminating "dark spots" that distort numbers. This consistency guarantees reliable readability, avoiding costly mistakes in industrial or consumer use cases. Industrial standard size: 30.1×16×7mm dimensions fit standard PCBs, sockets, and enclosures—no custom machining needed. Simplifies integration into existing designs (upgrading old audio equipment or retrofitting home appliance panels) and speeds up production for manufacturers. Stable performance & long lifespan: Built with high-quality LED chips and robust encapsulation to resist voltage fluctuations (common in home/industrial power systems) and mechanical vibration (in factory equipment or portable tools). Supports 50,000+ hours of continuous operation, reducing maintenance downtime. 4. Versatility & Regulatory Compliance Multi-color flexibility: Beyond super bright red, 6 additional colors cater to functional and aesthetic needs: Blue/white: For modern smart home devices . Amber/orange: For retro-style audio gear or kitchen appliances. Green: For "normal operation" indicators (e.g., process monitors showing safe levels). RoHS/REACH compliant: Free from lead, mercury, cadmium and hazardous chemicals , meeting global regulations for consumer electronics and industrial equipment. Ensures eligibility for export to key markets like the EU, North America, and Asia, aligning with eco-friendly product initiatives. Target Applications Optimized for triple-digit numeric display needs across consumer, audio, and industrial sectors: Audio Equipment & Instrument Panels: Amplifiers (volume levels, e.g., "45"), mixers (channel gains, e.g., "-3dB"), or equalizers (frequency settings, e.g., "1kHz"). Industrial instrument panels (pressure readings, e.g., "100kPa", or flow rates, e.g., "5L/min"). Home Electronic Appliances: Microwaves, induction cooktops, or small refrigerators. Smart home devices (humidity monitors, e.g., "55% RH", or battery chargers, e.g., "80%"). Numeric Displays: Retail price tags, queue number indicators , or digital signage. Process & Environmental Indicators: Industrial temperature monitors, warehouse humidity sensors, or production counters .
