The **M5R15XQJ-R** is a specific technical component part number, most commonly associated with **Electrolytic Capacitors** (often from manufacturers like Aishi, Man Yue/Samxon, or specialized power component suppliers). Based on the nomenclature typical for this series, here is the breakdown of the electronic specifications and part characteristics. --- ### 1. General Specifications This part is typically an **Aluminum Electrolytic Capacitor** designed for high-reliability applications such as power supplies and LED drivers. | Feature | Description | | :--- | :--- | | **Component Type** | Radial Aluminum Electrolytic Capacitor | | **Mounting Type** | Through-hole (Radial Leads) | | **Configuration** | Polarized | | **Common Application** | Filtering, Smoothing, and Buffering in AC/DC circuits | ### 2. Technical Characteristics While specific datasheets vary by manufacturer, the "M5" or "R15" segments usually denote physical dimensions or voltage ratings. Below are the standard performance parameters for this class of component: * **Capacitance Stability:** Designed to maintain low leakage current over time. * **Operating Temperature:** Generally rated for **-40°C to +105°C**, making it suitable for industrial environments. * **Load Life:** High endurance rating, typically between **2,000 to 5,000 hours** at maximum rated temperature. * **ESR (Equivalent Series Resistance):** Optimized for low impedance to handle ripple current effectively. ### 3. Part Number Decoding (Typical) Electronic part numbers are structured to provide specific data. For the **M5R15XQJ-R**: 1. **M5/R15:** Often refers to the **Lead Spacing** (e.g., 5mm) and **Case Diameter/Height** (e.g., 15mm height). 2. **XQ:** Usually identifies the **Series Code** (signifying specific performance like "High Ripple" or "Low Impedance"). 3. **J:** Often represents the **Capacitance Tolerance** (e.g., ±5% or ±20% depending on the manufacturer's code). 4. **-R:** Standard suffix for **RoHS Compliance** (Lead-free) or **Taped/Reel** packaging. ### 4. Application Areas * **Power Adapters:** Used for smoothing output voltage. * **Motherboards:** Localized power regulation. * **LED Lighting:** Used in drivers to prevent flickering. * **Consumer Electronics:** General-purpose DC-DC conversion. --- ### 5. Identification Check If you are replacing this part, ensure the following match the original component: 1. **Voltage (V):** Must be equal to or higher than the original. 2. **Capacitance (µF):** Must match the original specification. 3. **Physical Dimensions:** Ensure the diameter and height fit the PCB clearance.
