The **HTX-35V271MH10XQ-R2** is a high-performance surface-mount (SMD) aluminum electrolytic capacitor, typically manufactured by **Rubycon** (a part of the HTX series). These capacitors are designed for high-temperature environments and automotive-grade reliability. --- ### ## Technical Specifications | Parameter | Specification | | :--- | :--- | | **Capacitance** | 270 µF | | **Voltage Rating** | 35V DC | | **Tolerance** | ±20% | | **Operating Temperature Range** | -40°C to +125°C | | **Endurance (Lifetime)** | 2,000 to 5,000 hours at 125°C | | **Mounting Type** | Surface Mount (SMD / V-Chip) | | **Size Code** | 10mm (Diameter) x 10.5mm (Height) | | **Series** | HTX (High Temperature / Low ESR) | --- ### ## Key Features 1. **High Temperature Resilience:** The "HTX" series is specifically engineered to operate at **125°C**, which is significantly higher than standard 85°C or 105°C capacitors. 2. **Hybrid-like Performance:** While an electrolytic capacitor, the HTX series focuses on providing **Low ESR** (Equivalent Series Resistance), which improves efficiency and reduces heat generation during high ripple current situations. 3. **AEC-Q200 Compliance:** Parts like this are generally compliant with automotive stress test qualifications, making them suitable for under-the-hood electronics. 4. **Vibration Resistance:** The "R2" suffix often denotes a specific packaging or a vibration-proof base design, allowing the component to remain soldered securely in high-vibration environments. --- ### ## Part Number Breakdown The part number follows a specific nomenclature: | Segment | Meaning | | :--- | :--- | | **HTX** | Series Name (High temperature, low ESR) | | **35V** | Rated Voltage (35 Volts) | | **271** | Capacitance Code (27 + 1 zero = 270µF) | | **M** | Tolerance (M = ±20%) | | **H10** | Case Size Indicator (e.g., 10mm diameter) | | **XQ-R2** | Lead style and Taping/Packaging code | --- ### ## Typical Applications * **Automotive ECU:** Engine control units where ambient temperatures are high. * **DC/DC Converters:** Smoothing and filtering in power supplies. * **LED Lighting Drivers:** Industrial lighting where heat dissipation is a concern. * **Industrial Automation:** Controllers and sensors located near heavy machinery. ---
