Ultra Bright White 4-Digit 7-Segment Common Cathode LED Display for Oven Timers
High-temperature-resistant LED display engineered specifically for oven timers, temperature controllers, and home appliances. Features exceptional heat tolerance, superior visibility, and reliable performance in demanding kitchen environments.
Key Features
High-Temperature Resistance for Oven Use
- Wide working temperature range (+105°C to +120°C) withstands oven-side heat
- Fast heat-dissipation design maintains stable performance at maximum oven temperatures
- Protective film shields segments from kitchen grease, food splatters, and heat-induced discoloration
Superior Visibility for Kitchen Scenarios
- Ultra bright white illumination ensures clear readability in various lighting conditions
- Yellow segments on black face provide high contrast to eliminate washout
- Wide viewing angle maintains readability from off-center positions
Energy Efficiency & Reliable Performance
- Low power consumption minimizes energy use for oven timers
- Stable operation withstands temperature fluctuations and minor vibrations
- Long lifespan (50,000+ hours) matches 8-10 year service life of most ovens
Easy Integration & Versatility
- Common cathode polarity works with standard driver ICs (TM1637, HT1621, MAX7219)
- Designed for PCB direct-mounting with automated production compatibility
- Multiple color options available including red, blue, green, amber, and orange
- RoHS compliant for global market safety standards
