The **EXL1V0605-R82-R** is a high-performance, surface-mount (SMD) power inductor. It is specifically designed for high-current applications where stability, high frequency, and low energy loss are critical. --- ### 1. Technical Specifications The following table highlights the core electrical and physical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.82 µH | | **Tolerance** | ±20% | | **DC Resistance (DCR)** | ~4.1 mΩ (Typical) | | **Saturation Current ($I_{sat}$)** | ~17.5 A | | **Heating Current ($I_{rms}$)** | ~13.0 A | | **Operating Temperature** | -55°C to +125°C | | **Case Size** | 0605 (Metric 7164 approx.) | | **Construction** | Metal Composite / Shielded | --- ### 2. Part Number Breakdown Understanding the nomenclature helps in identifying the series and its capabilities: * **EXL:** Indicates the manufacturer's series (likely Cyntec or a similar high-current metal mold series). * **1V:** Designates the voltage rating or specific material composition (often low-profile, high-efficiency). * **0605:** The physical dimensions (approx. 7.1mm x 6.4mm). * **R82:** The inductance value ($0.82 \mu H$). * **R:** The tolerance (typically $\pm20\%$). --- ### 3. Key Features & Materials The EXL series utilizes a **Metal Alloy Powder** core rather than a traditional ferrite core. This provides several advantages: * **Soft Saturation:** Unlike ferrite inductors that drop inductance sharply when current limits are exceeded, this part loses inductance gradually, preventing sudden circuit failure. * **Magnetic Shielding:** The molded construction minimizes Electromagnetic Interference (EMI), making it suitable for high-density PCB layouts. * **Low DCR:** The use of flat wire or heavy-gauge copper minimizes "copper loss," reducing heat generation. --- ### 4. Typical Applications This inductor is commonly found in power management stages for modern electronics: 1. **DC-DC Converters:** Used as the main energy storage element in buck/boost converters. 2. **GPU/CPU Power Supply:** Handles the high-current, low-voltage requirements of modern processors (Vcore). 3. **Industrial Computing:** Reliable performance in environments with significant temperature fluctuations. 4. **Servers/Storage:** High-efficiency power modules (VRMs). ---
