The **M5R64RQ-R** is a high-performance **Molded Power Inductor** (typically manufactured by brands like Cyntec or similar power component specialists). These components are critical in modern electronics for voltage regulation and energy storage. --- ### 1. Technical Specifications The part number usually encodes specific technical attributes. Below is a breakdown of the typical characteristics for this series: | Property | Value (Typical) | | :--- | :--- | | **Inductance** | 0.64 µH | | **Tolerance** | ±20% | | **DC Resistance (DCR)** | ~0.85 mΩ (Ultra-low) | | **Saturation Current (Isat)** | ~40A - 50A | | **Heat Rating Current (Irms)** | ~30A - 35A | | **Operating Temperature** | -55°C to +125°C | | **Construction** | Metal Alloy / Molded Shielded | --- ### 2. Key Features * **Molded Construction:** The coil is encapsulated in a metallic magnetic powder mixture. This provides excellent EMI (Electromagnetic Interference) shielding and physical robustness. * **High Current Handling:** Due to the metal alloy core, it can handle very high saturation currents compared to traditional ferrite core inductors of the same size. * **Low DCR:** The use of thick flat-wire or high-quality copper results in extremely low DC resistance, which minimizes power loss and heat generation. * **Soft Saturation:** Unlike ferrite inductors that drop inductance sharply when overloaded, this part features "soft" saturation, making the circuit more stable under peak loads. --- ### 3. Common Applications These inductors are primarily found in high-density power stages: 1. **Voltage Regulator Modules (VRM):** Used in CPU/GPU power delivery on motherboards and server cards. 2. **DC-DC Converters:** Found in Point-of-Load (POL) converters for telecommunications and industrial computing. 3. **Battery Powered Systems:** Ideal for high-efficiency mobile devices where space is limited and thermal management is critical. --- ### 4. Footprint and Mounting The "R" at the end of the part number often signifies **Tape & Reel** packaging for automated SMT (Surface Mount Technology) assembly. The physical dimensions are typically compact (e.g., 5mm x 5mm or 6mm x 6mm range, depending on the specific package code within the M5R series).
