The **PI13050-R10M** is a high-current, shielded power inductor typically used in DC-DC converter applications and power management modules. It belongs to the category of "Molded Power Inductors," which are known for their compact size and high efficiency. ### 1. Key Technical Specifications The part number follows a standardized naming convention. Here is the breakdown of its primary electrical characteristics: | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 0.10 µH (indicated by "R10") | | **Tolerance** | ±20% (indicated by "M") | | **Case Size** | 13050 (Approx. 13.5 x 12.5 x 5.0 mm) | | **Core Material** | Metal Alloy Powder | | **Shielding** | Magnetic Shielding (Molded construction) | | **Operating Temperature** | Typically -40°C to +125°C | --- ### 2. Physical & Mechanical Attributes The "13050" designation refers to the physical dimensions of the component, which are critical for PCB layout design: * **Length:** ~13.5 mm * **Width:** ~12.5 mm * **Height:** ~5.0 mm * **Mounting:** Surface Mount Device (SMD/SMT) ### 3. Core Features and Benefits * **High Saturation Current:** Because it uses a metal alloy powder core, it can handle very high peak currents without the inductance dropping off sharply (soft saturation). * **Low DCR (DC Resistance):** Designed with thick copper wire to minimize power loss and heat generation. * **Low EMI:** The molded construction acts as a natural magnetic shield, reducing electromagnetic interference with surrounding components. * **High Frequency Performance:** Optimized for high-speed switching power supplies (typically up to 1MHz or higher). ### 4. Typical Applications These inductors are found in circuits where high power density and reliability are required: 1. **Voltage Regulator Modules (VRM):** For CPUs and GPUs. 2. **DC-DC Converters:** Point-of-Load (POL) power supplies. 3. **Battery Powered Systems:** Because of their high efficiency and small footprint. 4. **Servers and Networking:** High-current power rails. --- ### 5.
