### Technical Overview: FDV0630-R60M The **FDV0630-R60M** is a high-current, surface-mount (SMD) fixed inductor manufactured by **Murata Electronics**. It belongs to the metal alloy family of inductors, specifically designed for DC-DC converter applications where space and efficiency are critical. --- ### 1. Key Specifications Below are the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Inductance** | 0.6 µH | | **Tolerance** | ±20% | | **DC Resistance (DCR)** | 4.2 mΩ (Max) | | **Rated Current (Isat)** | 14.5 A (Saturation) | | **Rated Current (Itemp)** | 13.1 A (Temperature Rise) | | **Operating Temp Range** | -40°C to +125°C | | **Size / Dimension** | 7.4mm x 6.6mm | | **Height (Max)** | 3.0mm | --- ### 2. Core Material and Construction The "FDV" series utilizes a **Metal Alloy Core**. Unlike traditional ferrite cores, metal alloy cores offer several advantages: * **Soft Saturation:** The inductance drops gradually as current increases, preventing sudden spikes in current that could damage the circuit. * **Magnetic Shielding:** The molded construction provides excellent EMI (Electromagnetic Interference) shielding, reducing noise interference with neighboring components. * **Low Audible Noise:** The solid molded structure minimizes "buzzing" or acoustic noise caused by magnetostriction. --- ### 3. Part Number Deciphering To understand the variations, the part number can be broken down: | Segment | Meaning | | :--- | :--- | | **FDV** | Murata Series Name (Molded Power Inductor) | | **0630** | Dimensions (approx. 6mm x 6mm x 3mm) | | **R60** | Inductance Value (R60 = 0.60 µH) | | **M** | Tolerance (M = ±20%) | --- ### 4. Typical Applications Due to its high current handling and low profile, this part is commonly used in: * **CPU/GPU Power Supplies:** Used in Voltage Regulator Modules (VRMs) for laptops and desktop PCs. * **DC-DC Converters:** Point-of-Load (POL) converters for telecommunications and industrial equipment. * **Battery Powered Devices:** High efficiency ensures longer battery life due to low DCR losses. --- ### 5. Land Pattern (Footprint) When designing a PCB, the standard 0630 (Metric 7070) footprint is used. ```text Recommended Land Pattern: - Length: 7.4 mm - Width: 6.6 mm - Pad Width: 1.6 mm ```
