The **MV62V3CG-R** is a high-performance, surface-mount (SMD) Light Emitting Diode (LED) typically utilized in industrial displays, status indicators, and consumer electronics. It belongs to the sub-miniature chip LED category. --- ## 1. Technical Specifications The following table highlights the primary electrical and optical characteristics of the MV62V3CG-R: | Parameter | Specification | | :--- | :--- | | **Emitted Color** | Green (High Efficiency) | | **Lens Appearance** | Water Clear | | **Luminous Intensity** | ~15 - 40 mcd (at 20mA) | | **Forward Voltage ($V_F$)** | 2.1V (Typical) / 2.8V (Max) | | **Forward Current ($I_F$)** | 20mA (Continuous) | | **Peak Wavelength** | 565 nm - 570 nm | | **Viewing Angle** | 120 Degrees | | **Package Size** | 1206 (Metric 3216) | --- ## 2. Key Features * **Sub-miniature Footprint:** The 1206 package size allows for high-density mounting on Printed Circuit Boards (PCBs). * **Wide Viewing Angle:** The 120° spread ensures visibility from off-axis positions, making it ideal for backlighting. * **Reliability:** Designed for automated "pick and place" assembly and compatible with infrared (IR) reflow soldering. * **Low Power Consumption:** Operates efficiently at standard logic level currents (5mA to 20mA). --- ## 3. Circuit Integration To ensure the longevity of the MV62V3CG-R, a current-limiting resistor ($R$) must be used in series. You can calculate the resistor value using Ohm's Law: ### Formula $$R = \frac{V_{source} - V_{F}}{I_{F}}$$ ### Example Calculation If using a **5V** power supply and targeting **20mA** ($0.02A$): ```text R = (5V - 2.1V) / 0.02A R = 2.9V / 0.02A R = 145 Ohms (Use a 150 Ohm standard resistor) ``` --- ## 4. Typical Applications * **Status Indicators:** Power-on lights for routers, modems, and chargers. * **Backlighting:** Illuminating LCD screens or membrane switches. * **Automotive:** Dashboard icons and internal cabin lighting. * **Consumer Electronics:** Wearable devices where PCB space is limited.
