Based on the part number **BTL-52DRC-R2-P**, this component is a **5mm Round Through-Hole LED** typically manufactured by electronic component suppliers like Bright LED Electronics or similar manufacturers. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The **BTL-52DRC-R2-P** is an ultra-bright red LED designed for indicator lights, signage, and backlighting. | Parameter | Description | | :--- | :--- | | **LED Type** | Standard 5mm (T-1 3/4) | | **Emitted Color** | Red (Super Bright / Ultra Red) | | **Lens Appearance** | Water Clear (Transparent) | | **Mounting Type** | Through-Hole | | **Polarity** | Longer Lead is Anode (+), Shorter Lead is Cathode (-) | --- ### 2. Electro-Optical Characteristics These values are typical for the "DRC" (Deep Red/Super Bright) series under standard operating conditions ($I_F = 20mA$). | Property | Value (Typical) | Unit | | :--- | :--- | :--- | | **Forward Voltage ($V_F$)** | 1.8V - 2.4V | Volts | | **Forward Current ($I_F$)** | 20mA (Max 30mA) | mA | | **Luminous Intensity ($I_V$)** | 500 - 1500+ (Varies by bin) | mcd | | **Peak Wavelength ($\lambda_p$)** | 630nm - 660nm | nm | | **Viewing Angle** | 20° - 30° (Focused beam) | Degrees | --- ### 3. Absolute Maximum Ratings Exceeding these values can lead to permanent damage or shortened lifespan of the LED. * **Reverse Voltage:** 5V * **Power Dissipation:** 75mW - 100mW * **Operating Temperature:** -40°C to +85°C * **Lead Soldering Temperature:** 260°C for 5 seconds --- ### 4. Part Number Breakdown (Typical) While naming conventions vary slightly by brand, the code usually follows this logic: * **BT:** Manufacturer Prefix (e.g., Bright LED). * **L-5:** 5mm Diameter. * **2:** Round Head Shape. * **DRC:** Deep Red Color (GaAsP/GaP or AlGaInP material). * **R2:** Specific Brightness/Wavelength Binning or Revision 2. * **P:** Pb-Free (Lead-Free / RoHS Compliant). --- ### 5. Application Circuit Example To use this LED with a 5V power supply, a current-limiting resistor is required. ```cpp // Calculation: R = (V_supply - V_forward) / I_forward // R = (5V - 2.0V) / 0.02A = 150 Ohms ```
