The **HLMP-EJ32-R2000** is a high-performance LED manufactured by Broadcom (formerly Avago Technologies). It belongs to the T-1¾ (5mm) AllnGaP (Aluminum Indium Gallium Phosphide) series, known for high luminous efficiency and reliability in outdoor and industrial applications. --- ## Technical Specifications The table below highlights the primary electrical and optical characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Color** | Orange (Amber) | | **Dominant Wavelength** | 605 nm | | **Luminous Intensity** | 590 mcd to 1900 mcd (at 20mA) | | **Forward Voltage ($V_F$)** | 1.9V (Typ) to 2.4V (Max) | | **Viewing Angle** | 30° | | **Lens Shape/Size** | T-1¾ (5mm) Round | | **Lens Style** | Tinted, Non-diffused | | **Mounting Type** | Through Hole | --- ## Key Features ### 1. Material Technology (AllnGaP) The device uses **AllnGaP II** technology. Unlike older GaAsP technologies, AllnGaP provides significantly higher light output per watt and maintains stable performance over a wide range of temperatures. ### 2. Optical Characteristics * **High Luminous Intensity:** Designed to be visible in bright sunlight. * **Narrow Viewing Angle:** The 30-degree radiation pattern concentrates light into a beam, making it ideal for directional signaling rather than wide-area illumination. * **Color Stability:** Excellent color uniformity, crucial for panels using multiple LEDs. ### 3. Physical Construction * **Lead Frame:** Features an industry-standard lead frame for automatic insertion. * **Encapsulation:** The epoxy used is formulated for moisture resistance and durability in outdoor environments. --- ## Absolute Maximum Ratings To ensure the longevity of the part, the following limits must not be exceeded: | Parameter | Max Value | | :--- | :--- | | **Peak Forward Current** | 100 mA | | **DC Forward Current** | 50 mA | | **Reverse Voltage ($I_R = 100 \mu A$)** | 5 V | | **Operating Temperature** | -40°C to +100°C | | **Power Dissipation** | 120 mW | --- ## Typical Applications * **Commercial Outdoor Advertising:** Used in large-scale video screens and message boards. * **Traffic Management:** Variable message signs and pedestrian signals. * **Industrial Equipment:** Status indicators that require high visibility in well-lit factory environments. * **Automotive:** Interior lighting and dashboard indicators.
