The **MVH11V1CD-R** is an electronic component typically categorized as a **Chip Type Aluminum Electrolytic Capacitor**. These capacitors are designed for surface-mount technology (SMT) and are widely used in automotive electronics and power management circuits due to their high reliability. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series (often produced by manufacturers like Nippon Chemi-Con), here are the typical specifications: | Parameter | Specification | | :--- | :--- | | **Capacitance** | Varies by sub-code (e.g., 10µF to 470µF) | | **Voltage Rating** | Typically 35V to 50V DC | | **Tolerance** | ±20% (Standard) | | **Operating Temperature** | -40°C to +125°C | | **Life Expectancy** | 1,000 to 2,000 hours at 125°C | | **Mounting Type** | Surface Mount (SMD / V-Chip) | --- ### 2. Physical Construction The "CD-R" suffix and "V" designation usually refer to the packaging and structural design: * **V-Chip Design:** This refers to the vertical cylindrical shape with a flat plastic baseplate (seat), which allows it to be soldered directly onto a PCB using reflow soldering. * **Case Size:** The code indicates a specific diameter and height (e.g., 6.3mm x 7.7mm or similar), which is critical for PCB layout clearance. * **Vibration Resistance:** Parts ending in "-R" or specific automotive codes often feature enhanced mechanical structures to withstand high-vibration environments. --- ### 3. Key Features and Applications #### Features * **Low ESR:** Designed to handle ripple current efficiently without excessive heat buildup. * **High Temperature Stability:** Rated for 125°C, making it suitable for under-the-hood automotive applications. * **AEC-Q200 Qualified:** Frequently compliant with automotive stress test standards. #### Common Applications 1. **Automotive ECU:** Used in engine control units and power steering modules. 2. **DC/DC Converters:** Filtering noise and stabilizing voltage in power supplies. 3. **LED Lighting:** Drivers for automotive or industrial lighting systems. 4. **Industrial Controls:** Equipment operating in high-heat environments. --- ### 4. Part Number Breakdown (Generic) | Code Segment | Meaning | | :--- | :--- | | **MVH** | Series name (High temperature/Low impedance) | | **11V** | Voltage rating (e.g., 35V or specific series code) | | **1CD** | Capacitance code (Commonly 100µF or specific dielectric) | | **-R** | Taping/Reel packaging or Vibration-proof structure |
