The **LP5064R-R22M** is a high-current, shielded power inductor typically used in DC-DC converter applications. It is designed to handle high frequencies and large saturation currents while maintaining a small surface-mount footprint. --- ### 1. Technical Specifications The part number follows a specific nomenclature. Here are the primary electrical characteristics for this component: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.22 µH (Microhenries) | | **Tolerance** | ±20% (indicated by 'M') | | **DC Resistance (DCR)** | ~0.70 mΩ (Typical) | | **Saturation Current (Isat)** | ~50A to 60A | | **Heating Current (Irms)** | ~35A to 45A | | **Operating Temperature** | -40°C to +125°C | | **Package Size** | Approx. 13.5 x 12.5 x 6.4 mm | --- ### 2. Key Features * **Magnetic Shielding:** The inductor is constructed with a composite powdered iron or alloy core. This minimizes Electromagnetic Interference (EMI) and prevents magnetic flux from leaking into surrounding components. * **High Saturation:** Unlike standard ferrites, this core material has a "soft" saturation characteristic, meaning the inductance drops gradually rather than abruptly as current increases. * **Low DCR:** The use of flat wire or heavy-gauge copper winding ensures minimal power loss through heat (Joule heating), maximizing power supply efficiency. --- ### 3. Common Applications Due to its low inductance (0.22µH) and high current capability, the LP5064R-R22M is ideal for high-speed switching environments: 1. **Voltage Regulator Modules (VRM):** Used in CPU and GPU power delivery on motherboards. 2. **Point-of-Load (POL) Converters:** For stepping down voltages in telecommunication equipment. 3. **Battery Powered Systems:** Where high efficiency is critical to extending battery life. 4. **DC-DC Buck Converters:** Used in the output filter stage to smooth out current ripples. --- ### 4. Typical Footprint (Layout Example) When designing a PCB for this part, use wide copper traces to handle the high current density. ```markdown Recommended Pad Dimensions (Approximate): - Pad Width: 4.5 mm - Pad Length: 3.5 mm - Gap Between Pads: 7.0 mm ``` ---
