The **XF090604-R70M** is a high-current, surface-mount (SMD) power inductor commonly used in DC-DC converter applications. This component belongs to the "Molded Power Inductor" category, known for its compact size and high efficiency. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this type of component, here are the primary electrical and physical characteristics: | Parameter | Value / Description | | :--- | :--- | | **Inductance** | 0.70 µH (indicated by "R70") | | **Tolerance** | ±20% (indicated by "M") | | **Dimensions** | Approx. 9.0 x 6.0 x 4.0 mm (indicated by "090604") | | **Material** | Metal Alloy / Carbonyl Powder (Molded) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | --- ### 2. Breakdown of the Part Number Understanding the part number helps in identifying the physical and electrical limits of the component: * **XF**: Typically refers to the manufacturer's series code (often associated with high-frequency power inductors). * **090604**: Represents the physical footprint and height. * **09**: Length (~9.0mm) * **06**: Width (~6.0mm) * **04**: Height (~4.0mm) * **R70**: The Inductance value. "R" acts as a decimal point. **R70 = 0.70 microhenries (µH)**. * **M**: The tolerance code. **M = ±20%**. --- ### 3. Core Features and Benefits 1. **Magnetic Shielding**: Since it is a molded inductor, the wire is embedded in a metallic powder composite. This provides excellent EMI (Electromagnetic Interference) shielding and reduces acoustic noise. 2. **High Saturation Current**: These inductors are designed to handle high peak currents without the inductance dropping significantly (soft saturation). 3. **Low DCR (DC Resistance)**: Uses thick copper wire to minimize power loss and heat generation during operation. 4. **Stability**: High stability across a wide temperature range, typically -40°C to +125°C. --- ### 4. Common Applications Inductors with 0.70µH values are generally found in high-speed switching environments: * **Voltage Regulator Modules (VRMs)**: For CPUs and GPUs in laptops and servers. * **DC-DC Converters**: Point-of-load (POL) power supplies. * **Battery Powered Devices**: Where high efficiency and small footprint are critical. * **Automotive Electronics**: Infotainment and ADAS systems (if AEC-Q200 qualified). ---
