The **TCDA0707-R36M** is a high-performance, surface-mount (SMD) power inductor commonly used in DC-DC converter applications. It belongs to a class of shielded power inductors designed for high-current handling and high-frequency stability. ### Technical Specifications Below are the typical technical parameters for this specific component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.36 µH (indicated by "R36") | | **Tolerance** | ±20% (indicated by "M") | | **Case Size** | Approx. 7.0 x 7.0 mm (indicated by "0707") | | **Core Material** | Composite Alloy / Metal Powder | | **Shielding** | Magnetically Shielded | | **Mounting Type** | Surface Mount (SMD/SMT) | --- ### Key Electronic Characteristics #### 1. Low DC Resistance (DCR) The "0707" series is engineered with flat wire or optimized windings to ensure extremely low DC resistance. This minimizes power loss due to heat (I²R losses), making it highly efficient for battery-operated devices. #### 2. High Saturation Current ($I_{sat}$) Because it uses a metal alloy powder core, the inductor exhibits "soft saturation" characteristics. Unlike ferrite cores that drop inductance sharply when current limits are reached, this part maintains performance even during high current spikes. #### 3. Magnetic Shielding The component is fully shielded. This is critical for dense PCB layouts as it prevents electromagnetic interference (EMI) from affecting neighboring sensitive components, such as sensors or analog-to-digital converters. #### 4. Frequency Stability The R36M variant is designed to operate efficiently in high-switching frequency environments (typically between 500 kHz to 5 MHz), which are common in modern VRM (Voltage Regulator Modules). --- ### Common Applications * **Graphic Cards (GPUs):** Used in the power phases for high-speed processing units. * **Notebooks & Tablets:** High-efficiency CPU power supplies. * **DC/DC Converters:** Point-of-Load (POL) modules where space is limited but current demand is high. * **Servers:** Distributed power systems requiring high reliability. --- ### Part Number Breakdown * **TCDA**: Series designation (often proprietary to the manufacturer, e.g., Cyntec or similar). * **0707**: Physical dimensions (7.0mm x 7.0mm). * **R36**: Inductance value ($0.36 \mu H$). * **M**: Tolerance ($\pm 20\%$).
