## TPI13067F-R22M Electronic Part Overview The **TPI13067F-R22M** is a high-current, surface-mount (SMD) power inductor, typically manufactured by **ITG Electronics**. It is designed for high-frequency power conversion applications, particularly where space is limited and efficiency is critical. ### 1. Technical Specifications The alphanumeric code provides specific details regarding its electrical characteristics and physical dimensions: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.22 µH (220 nH) | | **Tolerance** | ±20% (indicated by 'M') | | **Type** | Flat Wire, High Current Inductor | | **DC Resistance (DCR)** | Extremely Low (typically < 0.3 mΩ) | | **Saturation Current ($I_{sat}$)** | Very High (often exceeding 60A - 100A) | | **Operating Temperature** | -40°C to +125°C | --- ### 2. Physical Characteristics The "13067" in the part number usually refers to the physical footprint of the component: * **Dimensions:** Approximately **13.5mm x 6.5mm** (length x width). * **Height:** The "7" often indicates a height of approximately **7.0mm**. * **Construction:** It uses a **Flat Wire** winding technique. Compared to round wire, flat wire reduces the skin effect at high frequencies and allows for a higher fill factor, which lowers DC resistance (DCR) and improves thermal management. --- ### 3. Key Features & Benefits * **Low Core Loss:** Uses advanced alloy powder cores to minimize energy loss during high-frequency switching. * **High Saturation:** Designed to handle large current spikes without the inductance dropping significantly (soft saturation). * **Shielded Design:** The molded construction provides magnetic shielding, reducing Electromagnetic Interference (EMI) with neighboring components. * **RoHS Compliant:** Meets environmental standards for lead-free electronics. --- ### 4. Common Applications This inductor is primarily found in high-performance power stages, including: 1. **Voltage Regulator Modules (VRMs):** Used in CPU and GPU power delivery on motherboards and server cards. 2. **DC-DC Converters:** High-efficiency buck, boost, or buck-boost converters. 3. **Distributed Power Systems:** Used in telecommunications and networking hardware. 4. **Industrial Computing:** Power supplies for high-load automation controllers. --- ### 5.
