The part number **HTX-16V820MF61Q-R2** refers to a high-performance **Conductive Polymer Hybrid Aluminum Electrolytic Capacitor**. These capacitors are designed to combine the low ESR (Equivalent Series Resistance) of conductive polymers with the high voltage and reliability of liquid electrolytes. --- ### 1. Technical Specification Breakdown Based on the standardized naming convention for this series, here is the technical profile: | Feature | Specification | | :--- | :--- | | **Capacitance** | 820 µF | | **Voltage Rating** | 16V DC | | **Technology** | Hybrid (Polymer + Electrolytic) | | **Case Size (Code)** | F61 (Typically approx. 8.0 x 10.2 mm or 10.0 x 10.5 mm) | | **Tolerance** | ±20% (Standard M-tolerance) | | **Temperature Range** | -55°C to +125°C or +135°C (HTX is a high-temp series) | | **Mounting Type** | Surface Mount (SMD) | --- ### 2. Key Characteristics of the HTX Series The "HTX" series is generally associated with high-temperature, high-reliability automotive or industrial grade components. * **Low ESR:** Because it uses a conductive polymer, it maintains extremely low resistance, which minimizes heat generation during high ripple current events. * **High Ripple Current:** It can handle significantly higher current loads compared to standard liquid electrolytic capacitors. * **Thermal Stability:** Unlike standard capacitors that dry out quickly at high temperatures, the hybrid design offers a long life (often 2,000 to 4,000 hours at 125°C+). * **Self-Healing:** The inclusion of a liquid electrolyte allows the capacitor to "heal" small dielectric defects, providing a safety margin against short circuits. --- ### 3. Common Applications Due to its 16V rating and 820µF capacity, this part is commonly used in: * **Automotive ECU:** Power filtering for engine control units. * **DC/DC Converters:** Smoothing output voltage in high-frequency switching power supplies. * **Telecommunications:** Base station power modules requiring high reliability. * **Industrial Robotics:** Motor drive circuits where vibration and heat resistance are required. --- ### 4.
