The **M3V63V1CJ-R** is a specific part number for a Surface Mount (SMD) Aluminum Electrolytic Capacitor, typically manufactured by companies like **ELNA** or similar high-quality passive component producers. Below is a breakdown of its technical specifications and electronic characteristics. --- ### 1. Technical Specifications | Parameter | Specification | Description | | :--- | :--- | :--- | | **Capacitance** | 100 µF (Typical) | The amount of electrical charge it can store. | | **Voltage Rating** | 63V DC | The maximum continuous voltage it can handle. | | **Mounting Type** | SMD (Surface Mount) | Designed for automated PCB assembly. | | **Package / Case** | V-Chip | Cylindrical metal can with a square plastic base. | | **Tolerance** | ±20% | Standard deviation allowed for capacitance value. | | **Operating Temp** | -40°C to +105°C | Designed for standard to industrial temperature ranges. | --- ### 2. Part Number Breakdown While naming conventions vary slightly by brand, the code usually decodes as follows: * **M3V**: Often refers to the series (Vertical Chip, high temperature/long life). * **63V**: The rated working voltage (63 Volts). * **1CJ**: Encoded value for capacitance and dimensions (where 'C' or 'J' often represents specific multipliers or tolerance). * **-R**: Generally indicates **Tape & Reel** packaging for automated pick-and-place machines. --- ### 3. Key Electronic Characteristics * **Polarity:** This is a **polarized** component. It must be installed in the correct orientation (indicated by a black/dark mark on the top of the cylinder) to avoid component failure or explosion. * **ESR (Equivalent Series Resistance):** These capacitors are designed to balance size with efficiency, providing filtering for power supply lines. * **Lifetime:** Rated for approximately 2,000 hours at its maximum operating temperature (105°C). In real-world conditions at lower temperatures, the lifespan extends significantly. --- ### 4. Common Applications 1. **DC-DC Converters:** Filtering input and output ripples. 2. **Automotive Electronics:** Used in infotainment or lighting control modules due to temperature stability. 3. **Power Supplies:** Providing bulk capacitance for voltage stabilization. 4. **Industrial Equipment:** General-purpose decoupling on control boards.
