The **APL0806P-R82M-C** is a high-performance, surface-mount (SMD) power inductor. These components are primarily used in voltage regulation circuits and power management modules to store energy and filter noise. --- ### 1. Technical Specifications | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 0.82 µH | | **Tolerance** | ±20% (indicated by 'M') | | **Package Size** | 0806 (Approx. 8.0 x 6.0 mm) | | **Type** | Shielded Power Inductor | | **Core Material** | Composite / Metal Powder (Molded) | | **Mounting Type** | Surface Mount (SMD/SMT) | --- ### 2. Part Number Breakdown Understanding the alphanumeric code helps identify its characteristics: * **APL**: Manufacturer series prefix (often associated with high-current molded inductors). * **0806**: Physical dimensions of the component (typically 8.0mm length and 6.0mm width). * **P**: Often denotes a specific material type or height profile. * **R82**: The Inductance value. "R" acts as a decimal point, so R82 = **0.82 µH**. * **M**: Tolerance code, where M represents **±20%**. * **C**: Often indicates the packaging style (e.g., Tape & Reel) or a specific revision code. --- ### 3. Key Features and Benefits * **High Current Handling:** Due to the molded metal powder construction, these inductors can handle high saturation currents without a sharp drop in inductance. * **Magnetic Shielding:** The molded design naturally shields the component, reducing Electromagnetic Interference (EMI) with surrounding components. * **Low DCR (DC Resistance):** Designed to minimize power loss as heat, increasing the overall efficiency of the power supply. * **Acoustic Noise Reduction:** The solid molded structure reduces the "buzzing" noise (magnetostriction) often found in traditional wire-wound inductors. --- ### 4. Common Applications These parts are typically found in the following electronic circuits: 1. **DC-DC Converters:** Used in "Buck" (step-down) converters to smooth output current. 2. **Motherboards & GPUs:** Filtering power for high-performance CPUs and Graphics processors. 3. **Battery Powered Devices:** Used in tablets and laptops where high efficiency and low profile are required. 4. **Automotive Electronics:** Infotainment and ADAS systems requiring stable power regulation.
