Technical Specifications Below is a breakdown of the key electrical and physical characteristics of this part: | Parameter | Value / Description | | :--- | :--- | | **Inductance** | 0.15 µH (Microhenries) | | **Tolerance** | ±20% (indicated by 'M' suffix) | | **Inductance Code** | R15 | | **Component Type** | Shielded Power Inductor | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Dimensions** | Approx. 7.0 x 7.0 x 3.0 mm (Series 07030) | --- ### 2. Part Number Breakdown The nomenclature for these inductors usually follows a specific manufacturer pattern (often associated with brands like Taiyo Yuden or similar high-current inductor manufacturers): * **TPI**: Series designation (typically Power Inductor). * **07030**: Physical size (7.0mm x 7.0mm footprint, 3.0mm height). * **F**: Designates material type or specific construction (often ferrite or composite). * **R15**: Inductance value (R = decimal point; 0.15 µH). * **M**: Tolerance (M = ±20%). --- ### 3. Key Electronic Features 1. **High Current Handling:** Due to the low inductance (0.15 µH), this part is designed to handle very high saturation currents ($I_{sat}$) and heating currents ($I_{rms}$), often exceeding 20-30 Amperes depending on the specific series. 2. **Magnetic Shielding:** The "F" series usually features a shielded construction, which minimizes electromagnetic interference (EMI) with surrounding components. 3. **Low DCR (DC Resistance):** Because it has very few windings, the internal resistance is extremely low, leading to high efficiency and minimal heat generation. 4. **High Switching Frequency:** Small inductance values like 0.15 µH are optimized for modern, high-speed switching power supplies (MHz range). --- ### 4. Common Applications This inductor is typically found in the following circuits: * **Voltage Regulator Modules (VRMs):** Used in CPU/GPU power delivery on motherboards. * **Point of Load (POL) Converters:** For stepping down voltage near the integrated circuit. * **High-Efficiency DC-DC Converters:** Used in telecommunications and server hardware. ---
