The part number **MALSECV00AG347CARK** refers to a high-quality surface-mount (SMD) Aluminum Electrolytic Capacitor, typically manufactured by **Vishay**. This component belongs to the **ECA** or **ECV** series, designed for general-purpose electronic filtering, decoupling, and energy storage. --- ### 1. Technical Specifications Based on the standard Vishay naming convention for the ECV series, here are the primary electrical and physical characteristics: | Property | Value / Specification | | :--- | :--- | | **Capacitance** | 47 µF (Microfarads) | | **Voltage Rating** | 16 V (Volts DC) | | **Tolerance** | ±20% | | **Mounting Type** | Surface Mount (SMD / V-Chip) | | **Operating Temp.** | -40°C to +85°C (Standard) | | **Polarity** | Polarized (Electrolytic) | | **Case Size** | Case Code C (approx. 5.0mm x 5.3mm) | --- ### 2. Breakdown of the Part Number The alphanumeric string can be decoded to understand the specific construction of the component: * **MAL**: Prefix for Vishay BCcomponents. * **SEC**: Designates the specific series (Standard SMD Electrolytic). * **V**: Indicates the "V-Chip" vertical surface mount package. * **00AG**: Internal factory/series code relating to the dielectric and life cycle (usually 2000 hours at 85°C). * **347C**: Represents the electrical value; "3" is the multiplier, "47" is the base value (47 x 10^0 = 47), and "C" often refers to the voltage rating (16V in this series). * **ARK**: Packaging suffix, typically indicating Tape and Reel (T&R) for automated pick-and-place assembly. --- ### 3. Common Applications These capacitors are widely used in consumer electronics and industrial power management due to their compact size and reliability. 1. **Filtering:** Used in DC-DC converters to smooth out voltage ripples. 2. **Decoupling:** Placed near ICs to provide a localized reservoir of energy, preventing voltage drops during high-speed switching. 3. **Bypass:** Redirecting AC noise to the ground to keep DC signals clean. 4. **Telecom & AV:** Found in telecommunication equipment, televisions, and audio-visual modules where PCB space is limited. --- ### 4. Handling and Soldering * **Reflow Soldering:** This part is designed for lead-free (Pb-free) reflow processes. * **Polarity:** Ensure the negative stripe (printed on the top of the can) aligns with the board markings to avoid component failure.
