The **M8YV-366-R** is a specific part number primarily associated with **high-frequency inductive components**, specifically a **Fixed Inductor / SMT Power Choke** typically manufactured by companies like Sumida or similar specialized electronic component providers. Below is the technical breakdown of its electronic characteristics and application profile. --- ## 1. Technical Specifications While exact parameters can vary slightly based on the specific manufacturing series, parts following the M8YV nomenclature generally adhere to these specifications: | Parameter | Typical Value | Notes | | :--- | :--- | :--- | | **Inductance** | 36.0 µH (nominal) | Indicated by the "366" code (36 x 10^0) | | **Mounting Type** | Surface Mount (SMT/SMD) | Designed for automated pick-and-place | | **Construction** | Shielded Drum Core | Reduces Electromagnetic Interference (EMI) | | **Tolerance** | ±20% (M) | Standard for power applications | | **Termination** | RoHS Compliant / Lead-Free | Matte Tin or Gold Flash finish | --- ## 2. Key Electronic Features ### A. Magnetic Shielding The "YV" series often implies a shielded construction. This means the magnetic flux is contained within the component body, preventing it from interfering with adjacent sensitive components on the PCB (Printed Circuit Board). ### B. Power Handling These parts are designed for low DC Resistance (DCR). Lower DCR translates to: * Higher efficiency. * Lower heat dissipation during high-current operations. * Better battery life in portable electronics. ### C. Saturation Current The core material is selected to maintain stable inductance even as the current increases. The "R" suffix often denotes a specific packaging type (Tape & Reel) or a revision involving improved saturation characteristics. --- ## 3. Typical Applications The M8YV-366-R is commonly found in the following electronic circuits: 1. **DC-DC Converters:** Used as energy storage elements in buck, boost, or buck-boost regulators. 2. **Noise Filtering:** Acts as a low-pass filter to remove high-frequency noise from power supply lines. 3. **Consumer Electronics:** Found in laptops, tablets, and LED driver circuits where space is limited but power efficiency is critical. --- ## 4.
