The **ECJ-RVC1H471K** is a specific part number for a Multilayer Ceramic Chip Capacitor (MLCC) manufactured by **Panasonic**. While this specific series is often categorized as "discontinued" or "legacy" in favor of newer series, its specifications follow standard industry naming conventions for high-reliability components. --- ## 1. Technical Specifications Below are the primary technical parameters for the ECJ-RVC1H471K: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Capacitance** | 470 pF | The energy storage capacity. | | **Tolerance** | ±10% (K) | The allowable variance from nominal capacitance. | | **Voltage (Rated)** | 50V (1H) | The maximum continuous DC voltage. | | **Dielectric** | X7R | Temperature stable (Operating range: -55°C to +125°C). | | **Package Size** | 0603 (Metric 1608) | Dimensions: 1.6mm x 0.8mm. | | **Mounting Type** | SMD/SMT | Surface Mount Technology. | --- ## 2. Part Number Breakdown Understanding the alphanumeric code helps in identifying the component's characteristics: 1. **ECJ**: Panasonic’s prefix for Multilayer Ceramic Capacitors. 2. **R**: High reliability or specific series designation (often associated with automotive or industrial grades). 3. **VC**: Refers to the physical dimensions and packaging style. 4. **1H**: Voltage Code (1H represents **50 Volts**). 5. **471**: Capacitance Code. The first two digits (47) are the value, and the third (1) is the multiplier (10^1). So, $47 \times 10 = 470 \text{ pF}$. 6. **K**: Tolerance Code (**±10%**). --- ## 3. Key Applications and Features * **X7R Dielectric:** This is a "Class II" ceramic material. It offers higher capacitance density than Class I (like C0G/NP0) but has a predictable change in capacitance over temperature $(\pm 15\%)$. * **Decoupling/Bypass:** Used extensively to filter out high-frequency noise from power supply lines to integrated circuits. * **General Purpose Electronics:** Found in consumer electronics, industrial controls, and automotive cabin systems where a stable 50V rating is required. * **Durability:** Panasonic capacitors in this series are designed for robust solderability and resistance to mechanical stress. --- ## 4. Lifecycle Status **Note:** The "ECJ" series has largely been phased out by Panasonic. If you are designing a new PCB, it is recommended to look at the **ECU** or **ECQ** series as modern equivalents, or look for cross-references from manufacturers like Murata (GRM series) or TDK (C series).
