| Model | Intensity | Angle | Best For |
|---|---|---|---|
| TLHR4401-AS12Z | 14mcd | 60° | General-purpose indicators |
| TLHR4401-AS15Z | 20mcd | 30° | Directional signaling |
| TLHR4401-AS18Z | 8mcd | 80° | Low-power ambient lights |
Approximately 50,000 hours at 25°C ambient temperature (per Vishay reliability testing).
Yes, but only for interior lighting (not AEC-Q101 qualified).
Yes, for 5V circuits, use a 150Ω resistor (calculated: (5V-2V)/20mA).
Luminous intensity decreases by ~0.5%/°C above 25°C (see datasheet derating curves).
5,000 units per reel (standard OEM packaging).
With rising demand for energy-efficient indicators, the TLHR440x series is well-positioned for IoT and smart home applications. Vishay’s roadmap suggests potential SMD variants by 2025.
