The **M3V61T1CJ-R** is a high-performance **Surface Mount (SMD) Aluminum Electrolytic Capacitor** from the **M3 series**, typically manufactured by companies like **Lelon** or **Nichicon** (depending on the specific sourcing line). It is designed for general-purpose applications requiring high capacitance in a compact form factor. --- ### 1. Key Technical Specifications Below are the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Capacitance** | 100 µF (standard for this part code) | | **Voltage Rating** | 16V DC | | **Tolerance** | ±20% at 120Hz, 20°C | | **Operating Temperature** | -40°C to +85°C | | **Package Type** | V-Chip (SMD) | | **Size Code** | 6.3mm x 5.4mm (approximate) | | **Life Cycles** | 2,000 hours at 85°C | --- ### 2. Breakdown of the Part Number While naming conventions can vary slightly by manufacturer, the code generally breaks down as follows: * **M3**: Series identifier (General Purpose / Standard 85°C). * **V**: Denotes "Vertical" or V-Chip (SMD) mounting style. * **61T**: Often refers to the size dimensions and capacitance multiplier. * **1C**: Voltage rating code (1C usually represents **16 Volts**). * **J-R**: Packaging/Tolerance indicator (R usually stands for **Tape & Reel** packaging). --- ### 3. Application Areas These capacitors are found in various electronic circuits due to their cost-effectiveness and reliability in non-extreme environments: * **Power Management:** Used for filtering and smoothing in DC-DC converters. * **Consumer Electronics:** Found in motherboards, peripheral devices, and display panels. * **Decoupling:** Providing a local energy reservoir for integrated circuits (ICs) to prevent voltage drops. * **Telecommunications:** Used in routers and networking hardware for signal stability. --- ### 4. Precautions for Use 1. **Polarity:** This is a polarized component. Ensure the negative stripe on the top of the casing aligns with the board markings to avoid explosion or failure. 2. **Reflow Soldering:** As an SMD component, it is designed for reflow soldering. Ensure the temperature profile does not exceed the component's maximum rating (usually around 250°C for a few seconds). 3. **ESR (Equivalent Series Resistance):** This is a standard ESR part; for high-frequency switching power supplies, a "Low ESR" series might be required instead. ---
