## RL0607-820-R Component Specifications The **RL0607-820-R** is a radial leaded power inductor (often referred to as a "peaking coil" or "fixed inductor") manufactured by **Bourns**. These components are designed for high-current applications and general-purpose filtering. --- ### 1. Key Technical Specifications | Parameter | Value | | :--- | :--- | | **Inductance** | 82 µH | | **Tolerance** | ±10% (Indicated by 'K') | | **Current Rating (I-dc)** | ~1.30 Amperes | | **DC Resistance (DCR)** | ~0.160 Ohms (Max) | | **Core Material** | Ferrite | | **Configuration** | Radial Leaded / Through-Hole | | **Lead Spacing** | ~5.0 mm | --- ### 2. Breakdown of the Part Number * **RL0607**: Refers to the series and physical size. "0607" generally indicates a body diameter of approximately 6mm and a height of 7mm. * **820**: The inductance code. The first two digits are the significant figures, and the third is the multiplier (number of zeros). * $82 \times 10^0 = 82 \text{ µH}$. * **R**: Typically indicates compliance with RoHS standards (Lead-free). --- ### 3. Physical Construction * **Winding:** Copper wire wound around a cylindrical ferrite core. * **Sleeve:** Usually covered with a flame-retardant polyolefin shrink tube to protect the windings and provide insulation. * **Terminals:** Tin-plated copper leads for easy soldering onto Printed Circuit Boards (PCBs). --- ### 4. Common Applications These inductors are commonly used in electronic circuits for power management and signal integrity: 1. **Switching Power Supplies:** Used as an energy storage element or output filter. 2. **EMI/RFI Filtering:** Suppressing high-frequency noise in power lines. 3. **DC-DC Converters:** Helping to smooth current ripples. 4. **Consumer Electronics:** Found in TVs, monitors, and household appliances. --- ### 5. Circuit Symbol In a schematic, it is represented by the standard inductor symbol: ```text L ----(UUU)---- 82 µH ```
