Based on the technical nomenclature, the **IA0204-R10KA** is typically identified as an **SMD Power Inductor**, specifically a low-resistance, high-current component often used in automotive or industrial power management. Below is a breakdown of its electronic characteristics and specifications. --- ### 1. Component Overview The IA0204 series belongs to the family of **Molded Power Inductors**. These are designed for high-density power applications where space is limited and electromagnetic interference (EMI) must be minimized. | Feature | Specification Details | | :--- | :--- | | **Component Type** | Fixed Inductor (SMD) | | **Inductance Value** | 0.10 µH (Indicated by R10) | | **Tolerance** | ±10% (Indicated by K) | | **Core Material** | Metal Alloy / Carbonyl Powder | | **Construction** | Shielded (Molded) | --- ### 2. Part Number Breakdown The alphanumeric code follows standard industry labeling for passive components: * **IA0204**: The series and physical dimensions. Usually, "0204" refers to the footprint size (e.g., approx. 2.0mm x 4.0mm or similar metric equivalents depending on the manufacturer). * **R10**: The Inductance value. "R" acts as the decimal point. $R10 = 0.10 \mu H$. * **K**: The tolerance rating. $K = \pm 10\%$. * **A**: Often denotes the packaging style (Tape & Reel) or an Automotive grade qualification (AEC-Q200). --- ### 3. Electrical Characteristics These inductors are characterized by their ability to handle high "Sat" (Saturation) currents without the inductance dropping significantly. | Parameter | Typical Value Range | | :--- | :--- | | **Inductance** | 0.10 µH | | **DC Resistance (DCR)** | Extremely Low (typically < 5 mΩ) | | **Saturation Current (Isat)** | High (often > 10A depending on size) | | **Operating Temperature** | -40°C to +125°C | --- ### 4. Typical Applications Because of the low inductance ($0.10 \mu H$) and high current capacity, this part is found in: 1. **Voltage Regulator Modules (VRM):** Used in CPU/GPU power delivery. 2. **DC-DC Converters:** High-frequency switching power supplies. 3. **Automotive Electronics:** Sensors, Infotainment, and ADAS systems. 4. **Telecom:** Compact base station power modules. --- ### 5. Mechanical & Soldering Considerations * **SMT Mounting:** Designed for automated pick-and-place assembly. * **Shielding:** The molded construction provides "self-shielding," reducing magnetic flux leakage that could interfere with nearby components. * **Reflow:** Generally compatible with lead-free (Pb-Free) reflow profiles.
