The **LP5064R-R60M** is a high-performance, surface-mount (SMD) power inductor. It is commonly used in DC-DC converters, voltage regulator modules (VRM), and high-current power supplies where space and efficiency are critical. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the physical and electrical characteristics: | Code Segment | Meaning | Specification | | :--- | :--- | :--- | | **LP** | Series Prefix | High-current power inductor series | | **5064** | Physical Size | Dimensions (approx. 13.0 x 13.0 mm) | | **R** | Designator | Specific core material/style | | **R60** | Inductance Value | 0.60 µH (Microhenries) | | **M** | Tolerance | ±20% | --- ### 2. Electrical Specifications While specific data can vary slightly by manufacturer (e.g., Cyntec or Coilcraft equivalents), the general parameters for a "R60" in this size class are: * **Inductance:** 0.60 µH * **DC Resistance (DCR):** Extremely low (typically < 1.0 mΩ) to minimize power loss. * **Isat (Saturation Current):** High current handling, often ranging from **40A to 60A**. This is the point where inductance drops by a specific percentage. * **Irms (Rated Current):** The continuous current that causes a specific temperature rise (usually 40°C). --- ### 3. Key Features * **Shielded Construction:** Magnetic shielding reduces Electromagnetic Interference (EMI), making it safe for dense PCB layouts. * **High Frequency:** Optimized for high-frequency switching (up to several MHz). * **Soft Saturation:** The core material usually allows for a graceful decline in inductance rather than a sharp drop-off during current spikes. * **Low DCR:** The use of flat wire or heavy-gauge copper reduces "Copper Loss," leading to higher efficiency. --- ### 4. Typical Applications The LP5064R-R60M is typically found in: 1. **Graphics Cards (GPUs):** Powering the core rails of high-end video cards. 2. **Server Motherboards:** VRM circuits for multi-core CPUs. 3. **Telecom Power Brick:** Distributed power systems and high-current point-of-load (POL) converters. 4. **Laptop Power Stages:** High-efficiency buck converters. --- ### 5.
