The **MEH53XBG-R** is a high-performance, shielded power inductor manufactured by **Coilcraft**. It is part of the MEH53 series, designed for high-current applications where space-saving and thermal stability are critical. --- ### 1. Key Technical Specifications The following table highlights the primary electrical characteristics of the MEH53XBG-R: | Feature | Specification | | :--- | :--- | | **Inductance** | 0.53 µH | | **Tolerance** | ±20% | | **DCR (DC Resistance)** | 1.85 mΩ (Nominal) | | **Isat (Saturation Current)** | ~25.0 Amperes | | **Irms (Heating Current)** | ~18.5 Amperes | | **Shielding** | Magnetically Shielded | | **Operating Temperature** | -40°C to +125°C | --- ### 2. Physical Construction and Form Factor The "XBG" suffix refers to the specific sizing and termination style of the component. * **Size/Footprint:** It typically occupies a footprint of approximately 5.5 x 5.3 mm with a low profile (height around 3.0 mm). * **Material:** It uses a composite core construction. This minimizes "buzz" noise and provides a soft saturation characteristic, meaning the inductance doesn't drop off instantly when current exceeds limits. * **Shielding:** The magnetic shielding prevents electromagnetic interference (EMI) from affecting nearby sensitive components on the PCB. --- ### 3. Common Applications Due to its high current handling and low DCR, the MEH53XBG-R is commonly found in: 1. **Voltage Regulator Modules (VRMs):** Used in CPUs and GPUs for efficient power delivery. 2. **DC-DC Converters:** Ideal for "Point of Load" (POL) converters in telecommunications and industrial computing. 3. **Battery Powered Devices:** High efficiency (low DCR) extends battery life by reducing heat loss. 4. **Automotive Electronics:** Used in infotainment and ADAS systems where compact, heat-resistant parts are required. --- ### 4. Part Number Breakdown While manufacturer codes vary slightly, the string generally translates as: * **MEH53:** Series name (High current, shielded). * **X:** Specialized testing or internal code. * **BG:** Specific Inductance value / Mechanical variation. * **R:** Packaging (usually refers to Tape and Reel).
