The **SES-2A0-R/E** is a specific electronic component within the category of **High-Frequency (HF) and Power Inductors/Transformers**, often used in telecommunications and power management circuits. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Overview The SES series typically refers to **Surface Mount (SMT) Inductors** or **Common Mode Chokes**. The "2A0" designation usually indicates its physical size or basic power rating, while "R/E" signifies RoHS compliance and specific packaging or tolerance variations. ### 2. Technical Specifications While exact specs can vary by manufacturer (such as Sumida or similar magnetic component specialists), the general profile for this part is as follows: | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Power Inductor / Surface Mount Device (SMD) | | **Inductance Range** | Typically fixed (refer to datasheet for specific Henries) | | **Current Rating** | High Current handling (optimized for DC-DC conversion) | | **Construction** | Shielded or Unshielded magnetic core | | **Operating Temp** | -40°C to +125°C (Automotive/Industrial grade) | | **Compliance** | RoHS / Lead-Free (R/E suffix) | --- ### 3. Key Electronic Functions The SES-2A0-R/E performs several critical roles in a circuit: 1. **Energy Storage:** Acts as the primary energy storage element in switching regulators (Buck/Boost converters). 2. **Filtering:** Smooths out ripples in output voltage by resisting changes in current flow. 3. **EMI Suppression:** The "shielded" nature of many SES models helps prevent Electromagnetic Interference from affecting nearby sensitive components. 4. **Impedance Matching:** Used in RF stages to ensure maximum power transfer between stages. --- ### 4. Typical Applications This component is commonly found in: * **Mobile Devices:** Power management ICs (PMICs). * **Automotive Electronics:** Navigation systems and ECU power supplies. * **Telecommunications:** Base stations and network routers. * **Industrial:** DC-DC converter modules. --- ### 5. Part Number Breakdown (Generic) * **SES:** Series name (Surface mount, Energy Storage/Shielded). * **2A0:** Size code (refers to dimensions, e.g., 2mm height or footprint category). * **R/E:** * **R:** Tape & Reel packaging. * **E:** Environmental standard (Green/RoHS compliant).
