The **MA23TAG-R** is a specialized electronic component, typically categorized as a **Surface Mount Device (SMD) Power Inductor** or a specific high-frequency magnetic component used in compact power management circuits. Below is a breakdown of its core electronic characteristics, technical specifications, and typical applications. --- ### 1. Key Technical Specifications While specifications can vary slightly by manufacturer (often associated with brands like **Sunlord** or **TDK**), the "MA" series generally follows these parameters: | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Fixed Inductor (Multilayer Chip Inductor) | | **Inductance** | Usually in the range of 0.47µH to 2.2µH (Specific to the "23" sizing) | | **Case Size** | 0805 (Metric 2012) or specific proprietary molding | | **Tolerance** | ±20% (Standard for power inductors) | | **DC Resistance (DCR)** | Low (typically < 100 mΩ) to minimize power loss | | **Saturation Current** | High (optimized for DC-DC conversion) | | **Operating Temp** | -40°C to +125°C | --- ### 2. Physical Construction The "R" suffix often denotes **RoHS compliance** and **Tape & Reel** packaging for automated pick-and-place assembly. * **Magnetic Shielding:** These parts are usually magnetically shielded to prevent Electromagnetic Interference (EMI) with neighboring components on a dense PCB. * **Multilayer Technology:** Unlike wire-wound inductors, these use layers of conductive paste and ferrite material to achieve high inductance in a small footprint. --- ### 3. Circuit Functions The MA23TAG-R is primarily used in the following roles: 1. **Power Decoupling:** Filtering out high-frequency noise from power supply lines. 2. **Energy Storage:** Acting as the storage element in small Buck/Boost DC-DC converters. 3. **EMI Suppression:** Reducing the electromagnetic noise generated by high-speed switching circuits in mobile devices. ### 4. Typical Applications * **Mobile Hardware:** Smartphones, tablets, and wearable tech. * **IoT Modules:** Low-power wireless sensors requiring compact power stages. * **SSD Controllers:** Providing stable voltage rails for high-speed data processing. --- ### 5. Identification Example If you are looking at the part marking: ```text M - Multilayer / Magnetic A - Series Code (Application specific) 23 - Physical Dimensions (e.g., 2.0mm x 1.2mm) T - Tape & Reel Packaging AG - Specific Material/Tolerance code R - RoHS Compliant ```
