The **LTCEC-13002-R/Q** is a high-precision electronic component, typically categorized as a **Chip Inductor** or a **Common Mode Choke**, depending on the specific manufacturer series (often associated with automotive or high-reliability power applications). Below is a breakdown of its technical characteristics and electronic properties. --- ### 1. Technical Specifications Overview This component is designed for Surface Mount Technology (SMT) and is optimized for noise suppression or energy storage in compact circuits. | Feature | Specification Details | | :--- | :--- | | **Component Type** | SMD Power Inductor / Common Mode Filter | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Tolerance** | Typically ±20% (standard for power inductors) | | **Operating Temp** | -40°C to +125°C (Automotive Grade) | | **Core Material** | Ferrite (High permeability) | | **Shielding** | Magnetically Shielded (to prevent EMI) | --- ### 2. Key Electronic Functions The "13002" designation usually refers to the physical dimensions and specific winding characteristics of the part. * **EMI Suppression:** The "R/Q" variants are often utilized to filter out high-frequency electromagnetic interference (EMI) in power lines. * **DC Resistance (DCR):** Designed with extremely low DCR to minimize power loss and heat generation during operation. * **Saturation Current:** These parts are engineered to handle high peak currents without the inductance dropping significantly (saturation). * **Impedance Matching:** Used in high-speed data lines or power conversion stages to ensure signal integrity. --- ### 3. Application Areas Because of the "Q" designation (which often implies AEC-Q200 qualification in the industry), these parts are frequently found in: 1. **Automotive Electronics:** Infotainment systems, ADAS sensors, and ECU power filtering. 2. **DC/DC Converters:** Voltage regulation modules for laptops and industrial servers. 3. **Communication Infrastructure:** Base stations and high-speed networking hardware where noise isolation is critical. --- ### 4. Part Number Breakdown (Typical) While naming conventions vary slightly by manufacturer, the code generally follows this logic: ```text LTC - EC - 13002 - R/Q ^ ^ ^ ^ Brand/ Type Size/ Variation/ Series Code Value Quality Grade (e.g., RoHS/Qualified) ```
