The part number **MCQ1V3216-R180-R** typically refers to a **Multilayer Chip Inductor** (specifically a ferrite chip bead or power inductor) often used in high-frequency circuits for noise suppression or energy storage. Below is the detailed breakdown of its specifications and characteristics. --- ### 1. Part Number Deciphering Most manufacturers (like Microgate or Chilisin) follow a standard naming convention for this series: | Segment | Code | Meaning | | :--- | :--- | :--- | | **Series** | MCQ | Multilayer Chip Inductor / Ferrite Bead | | **Type** | 1V | Voltage/Material specific code (Low DC resistance type) | | **Size** | 3216 | Metric: 3.2mm x 1.6mm (EIA 1206 Case Size) | | **Value** | R180 | Inductance: 0.18 µH (180nH) | | **Tolerance** | - | Usually ±20% (M) or ±10% (K) if not specified | | **Packaging** | -R | Taping & Reel (RoHS Compliant) | --- ### 2. Technical Specifications The following values are typical for an 180nH inductor in a 1206 package: * **Inductance:** 0.18 µH (180 nH) * **Case Size:** 1206 (3216 Metric) * **DC Resistance (DCR):** Low (typically < 0.20 Ω) to minimize power loss. * **Rated Current:** Usually ranges between 200mA to 800mA depending on the specific sub-series. * **Self-Resonant Frequency (SRF):** High, typically above 200 MHz, making it suitable for high-frequency filtering. * **Operating Temperature:** -55°C to +125°C. --- ### 3. Construction and Material * **Structure:** Multilayer ceramic/ferrite technology. It is a monolithic structure (solid block) which provides excellent magnetic shielding, preventing interference with neighboring components. * **Terminations:** Solder-plated (Ni/Sn) for excellent solderability and heat resistance during reflow. --- ### 4. Common Applications This specific part is used in circuits where space is limited and EMI (Electromagnetic Interference) must be controlled: 1. **Power Supply Decoupling:** Used to filter high-frequency noise in DC-DC converters. 2. **Signal Line Filtering:** Used in high-speed data lines to prevent signal distortion from external noise. 3. **Consumer Electronics:** Found in smartphones, tablets, and motherboards for power management modules. 4. **RF Circuits:** Used in the matching networks of communication devices. --- ### 5.
