The part number **CE-XXYYV-RUBYCON** is a standardized format used to identify **Aluminum Electrolytic Capacitors** manufactured by **Rubycon Corporation**, a leading Japanese electronic components company. Below is a breakdown of the electronic specifications and the naming convention typically associated with this series. --- ### 1. Part Number Breakdown While "XXYYV" serves as a placeholder for specific values, the structure typically follows this logic: | Segment | Component | Description | | :--- | :--- | :--- | | **CE** | **Category** | Indicates a Surface Mount (Chip) Type Aluminum Electrolytic Capacitor. | | **XX** | **Series Code** | e.g., *ZA, ZV, JX*. Defines life hours, temperature range, and ESR. | | **YY** | **Capacitance** | The value in Microfarads (µF). | | **V** | **Voltage** | The Rated Working Voltage (WV). | | **RUBYCON** | **Brand** | The manufacturer (Japan). | --- ### 2. Key Technical Characteristics Rubycon CE-series capacitors are generally **Surface Mount Devices (SMD)** designed for automated assembly. #### A. Dielectric & Construction * **Anode:** High-purity aluminum foil with an etched surface to increase area. * **Electrolyte:** A liquid or gel conducting medium. * **Case:** Cylindrical aluminum "can" mounted on a plastic base (vertical chip type). #### B. Performance Metrics * **Operating Temperature:** Typically ranges from **-40°C to +105°C** (Standard) or **+125°C** (High temp). * **Load Life:** Usually rated between **1,000 to 5,000 hours** at their maximum rated temperature. * **Polarity:** These are **polarized** components. The negative terminal is usually marked with a black or colored bar on the top of the casing. --- ### 3. Common Series Examples If "XX" represents a specific Rubycon series, here are the most common variants: | Series | Type | Key Feature | | :--- | :--- | :--- | | **CE-ZA** | Low ESR | High ripple current, used in power supplies. | | **CE-ZV** | Standard | General purpose, cost-effective for consumer electronics. | | **CE-JX** | Long Life | High reliability for automotive or industrial use. | | **CE-TZ** | Low Profile | Designed for ultra-thin electronic devices. | --- ### 4. Applications These capacitors are found in virtually all modern electronic circuits for: 1. **Filtering:** Smoothing rectified DC power. 2. **Decoupling:** Reducing noise in high-frequency circuits. 3. **Energy Storage:** Providing bursts of current when needed. 4. **Bypassing:** Diverting AC signals around a component. --- ### 5. Identification Checklist When replacing a **CE-XXYYV-RUBYCON** part, always verify: * **Voltage:** Must be equal to or higher than the original. * **Capacitance:** Should match the original (usually measured in µF). * **Physical Size:** Check the diameter (D) and height (L) to ensure it fits the PCB footprint.
