The **M3V63V2CJ-R** is a specific part number for a Surface Mount Device (SMD) Aluminum Electrolytic Capacitor, typically manufactured by companies like Elna or other specialized passive component vendors. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications Based on standard industry nomenclature for this series, here is the technical profile: | Parameter | Specification | | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor | | **Mounting Type** | Surface Mount (SMD / V-Chip) | | **Capacitance** | 3.3 µF (Microfarads) | | **Voltage Rating** | 63V DC | | **Tolerance** | ±20% (Standard) | | **Operating Temperature** | -40°C to +105°C | | **Lifetime/Endurance** | 2000 hours at 105°C (Typical) | --- ### 2. Part Number Breakdown The alphanumeric code identifies the physical and electrical constraints of the part: * **M3V**: Often refers to the series name (High temperature, long life, or vertical chip type). * **63V**: Indicates the Maximum Working Voltage (63 Volts). * **2CJ**: Usually a proprietary code for the **Case Size** (e.g., 4mm x 5.3mm or 5mm x 5.3mm) and **Packaging** (Tape and Reel). * **-R**: Indicates compliance with **RoHS** (Restriction of Hazardous Substances) standards. --- ### 3. Key Electronic Characteristics #### A. Dielectric Structure This part uses an aluminum oxide layer as the dielectric and a liquid electrolyte. This allows for high capacitance in a small volume compared to ceramic capacitors. #### B. Equivalent Series Resistance (ESR) As an electrolytic capacitor, it will have a measurable ESR. Because this is a 63V rated part, it is often used in power filtering where it can handle voltage spikes effectively, though its ESR is generally higher than tantalum or MLCC alternatives. #### C. Polarized Nature This component is **polarized**. The PCB footprint must account for the positive and negative terminals. Reversing the polarity will lead to component failure or explosion. --- ### 4. Common Applications Due to its 63V rating and small SMD form factor, it is commonly found in: * **DC-DC Converters:** Filtering input/output noise in power supplies. * **Industrial Controls:** 24V or 48V rail decoupling. * **Automotive Electronics:** Sensors and modules requiring 105°C temperature ratings. * **Telecommunications:** Power management in networking hardware. ---
