The **ALV-613-R** is a specific electronic component, typically categorized as a **Surface Mount Device (SMD) LED indicator**, often used in specialized networking equipment, industrial panels, and automotive dashboards. Below is a breakdown of its technical specifications and electronic characteristics. --- ### 1. Technical Specifications The "ALV" series generally refers to Side-View or Right-Angle LEDs. The "R" suffix typically denotes the color **Red**. | Parameter | Specification (Typical) | | :--- | :--- | | **Package Type** | SMD / SMT (Surface Mount) | | **Mounting Orientation** | Right Angle (Side View) | | **Color** | Red | | **Dominant Wavelength** | ~620nm - 630nm | | **Forward Voltage ($V_f$)** | 1.8V to 2.4V | | **Forward Current ($I_f$)** | 20mA (Typical) | | **Luminous Intensity** | 50 - 150 mcd (varies by bin) | | **Viewing Angle** | 120° | --- ### 2. Physical Characteristics The ALV-613-R is designed for space-constrained applications where the light needs to be emitted parallel to the PCB. * **Form Factor:** It utilizes a small footprint (often similar to 1206 or specific manufacturer-defined dimensions). * **Lens Type:** Usually water-clear or diffused, depending on the specific sub-model. * **Soldering:** Compatible with lead-free reflow soldering processes. --- ### 3. Application Use Cases This component is frequently found in: 1. **Network Switches/Routers:** As status indicators on the edge of the board. 2. **Handheld Devices:** For battery or power status where vertical height is limited. 3. **Backlighting:** For LCD screens or membrane switches. --- ### 4. Circuit Integration Example To use the ALV-613-R in a 5V circuit, a current-limiting resistor is required to prevent burnout. ```cpp // Calculation for Resistor (R): // R = (V_source - V_forward) / I_forward // R = (5V - 2.0V) / 0.020A = 150 Ohms ``` ---
