Key Features
8-Digit Design: 0.28-inch (7mm) character height and 22×38×7mm dimensions provide ample space for extended numeric readouts (e.g., long codes, precise temperatures), perfect for set-top boxes and instrument panels.
Ultra Bright Red Emission: Vivid red light ensures high visibility, with versatile color options (blue, yellow green, pure green, amber, orange, pure white) to match device aesthetics.
High Luminous Intensity: 80-100mcd output guarantees clarity in both bright and dim environments, critical for temperature/humidity indicators and home appliances.
Energy Efficiency: Low forward voltage (1.8-2.2V/LED) and optimized current (5-10mA/LED) minimize power usage, enhancing device efficiency and longevity.
Uniform Segments: White segments on a black surface ensure consistent light distribution across all 8 digits, ensuring crisp readability for extended numeric displays.
Easy Integration: Common cathode configuration, IC compatibility, and simple assembly streamline installation into PC boards, reducing manufacturing complexity.
Durable & Compliant: Stable performance, long lifespan, and RoHS compliance ensure reliability in daily use for household and industrial applications.
