The **CVR1-AF-R/CE** is a specialized electronic component primarily categorized as an **Electrolytic Capacitor**, specifically from the **CVR Series** manufactured by **Cal-Chip Electronics**. Below is a detailed breakdown of its technical characteristics and internal parts. --- ### 1. Technical Specifications The part number follows a standard nomenclature used by Cal-Chip. Here are the core parameters for this specific series: | Parameter | Detail | | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor | | **Mounting Type** | Surface Mount Device (SMD) / V-Chip | | **Series** | CVR (Standard Type, 85°C) | | **Termination** | RoHs Compliant / Lead-Free (CE Suffix) | | **Packaging** | Tape & Reel (R Suffix) | --- ### 2. Internal Electronic Construction An electrolytic capacitor like the CVR1 is composed of several critical internal "parts" that define its performance: 1. **Anode Foil:** High-purity aluminum foil that has been etched to increase surface area and "formed" with an aluminum oxide dielectric layer. 2. **Cathode Foil:** A plain or etched aluminum foil that acts as the second electrode. 3. **Electrolyte:** A liquid or gel conductive medium that maintains the electrical contact between the cathode and the dielectric. 4. **Separator Paper:** A porous paper that holds the electrolyte in place and prevents a physical short circuit between the anode and cathode foils. 5. **Aluminum Can:** The outer cylindrical housing that protects the internal elements from environmental moisture. 6. **Sealing Rubber:** Located at the bottom to prevent the electrolyte from leaking or evaporating. 7. **Lead Terminals:** For SMD versions, these are attached to a plastic base platform (the "V-Chip" design) for automated soldering. --- ### 3. Application Use Cases As a general-purpose SMD electrolytic capacitor, this part is used in: * **Decoupling:** Removing high-frequency noise from power supply lines. * **Filtering:** Smoothing rectified DC voltage in power adapters. * **Energy Storage:** Providing temporary power for low-voltage circuits. * **Coupling:** Passing AC signals while blocking DC components in audio circuits. --- ### 4. Part Number Breakdown * **CVR:** Series identifier (Vertical Chip Aluminum Electrolytic). * **1:** Often denotes a specific voltage rating or size code (varies by manufacturer datasheet). * **AF:** Case size or capacitance code. * **R:** Packaging (Tape & Reel). * **CE:** Compliance mark (typically indicating RoHS/Lead-Free standards).
