## HLMP-AB01-R0T00: Product Overview The **HLMP-AB01-R0T00** is a high-performance Blue LED produced by Broadcom (formerly Avago Technologies). It is part of the HLMP-Ax01 series, specifically designed for high-visibility applications. --- ### 1. Key Technical Specifications Below are the primary electronic and optical characteristics of the device: | Parameter | Specification | | :--- | :--- | | **Color** | Blue | | **Dominant Wavelength** | 470 nm | | **Luminous Intensity** | 240 mcd to 760 mcd | | **Viewing Angle** | 30 Degrees | | **Lens Shape** | Round (T-1 3/4) | | **Lens Size** | 5 mm | | **Forward Current ($I_F$)** | 30 mA (Typical) | | **Forward Voltage ($V_F$)** | 3.2 V to 3.8 V | | **Mounting Type** | Through-Hole | --- ### 2. Core Features * **Technology:** Uses Indium Gallium Nitride (InGaN) chip material, which allows for high light output efficiency. * **Optics:** Features an oval/round radiation pattern that is well-suited for outdoor signs where wide horizontal viewing is required but narrow vertical viewing is sufficient. * **Durability:** The lead frames are usually made of iron/copper alloy with silver plating to ensure high thermal conductivity and reliable soldering. * **Standoffs:** This specific model typically includes "standoffs" on the leads to ensure proper seating on the PCB and to facilitate easier cleaning after soldering. --- ### 3. Pinout and Circuit Representation The device is a standard two-lead diode. ```text (Anode) + ----|>|---- - (Cathode) Longer Lead Shorter Lead (Flat side) ``` --- ### 4. Typical Applications Due to its high brightness and specific color point, the HLMP-AB01-R0T00 is commonly used in: 1. **Variable Message Signs (VMS):** Traffic and informational signs. 2. **Commercial Outdoor Advertising:** Large LED billboards. 3. **Status Indicators:** Industrial equipment panels requiring high visibility under sunlight. 4. **Decorative Lighting:** Architectural accents. ---
