Key Features
1. Microwave-Specific Durability
High-Temperature Resistance: Operates reliably at +105°C to 120°C, enduring the heat generated by microwave ovens—critical for avoiding display failure in closed, high-heat environments.
Robust Construction: Engineered to withstand minor vibrations and temperature fluctuations common in kitchen appliance use, ensuring consistent performance over time.
2. Superior Visibility
Ultra Bright White Illumination: Delivers intense, uniform white light that cuts through kitchen glare and microwave door tint, making timer values (e.g., "02:30" for 2 minutes 30 seconds) easy to read at a glance.
0.49inch Character Height: Spacious numeric size balances readability and package compactness, ideal for microwave control panels where visibility is key for user convenience.
Big Viewing Angle: Wide viewing range ensures clear readability from multiple positions (e.g., standing or sitting), enhancing user experience.
3. Easy Integration & Customization
Common Cathode Configuration: Simplifies circuit design with microwave control boards and standard driver ICs, reducing development time for manufacturers.
SMD Pin Type: Surface-mount design enables secure, space-efficient PCB mounting, compatible with automated production lines for high-volume appliance manufacturing.
Customizable Options: Tailored package size (61×43×20mm) and multiple LED color choices (red/blue/green/white/amber/orange) to match specific microwave design requirements.
4. Energy Efficiency & Compliance
Low Power Consumption: Optimized current draw minimizes energy use, aligning with modern appliance energy efficiency standards.
Global Safety Compliance: Meets RoHS/REACH regulations, ensuring compatibility with international markets and adherence to environmental safety norms.
