The **HTX-63V101MHC5XQ-R2** is a specific part number for a high-performance **Surface Mount (SMD) Aluminum Electrolytic Capacitor**. These components are widely used in power management and filtering applications due to their high voltage rating and temperature resilience. --- ## 1. Technical Specifications Based on the part number nomenclature (typically associated with manufacturers like **Lelon** or similar high-reliability brands), here are the core technical parameters: | Parameter | Value | | :--- | :--- | | **Capacitance** | 100 µF (indicated by "101") | | **Voltage Rating** | 63 VDC | | **Tolerance** | ±20% (M) | | **Mounting Type** | SMD (Surface Mount Device) / V-Chip | | **Series** | HTX (High Temperature / Low ESR) | | **Case Size** | Approx. 8 x 10.5 mm or 10 x 10.5 mm | | **Operating Temperature** | -55°C to +125°C | | **Life Cycles** | Typically 2,000 to 5,000 hours at 125°C | --- ## 2. Key Features and Benefits ### A. High Temperature Endurance The "HTX" series is designed for harsh environments. While standard capacitors fail at 85°C or 105°C, this unit can operate at **125°C**, making it suitable for automotive and industrial under-the-hood electronics. ### B. Low ESR (Equivalent Series Resistance) This capacitor is engineered to have low internal resistance. This allows it to handle higher **ripple currents** without overheating, which improves the efficiency of power converters. ### C. Mechanical Stability The "V-Chip" vertical surface mount design allows for automated pick-and-place assembly. The "R2" suffix often denotes specific packaging (like Tape & Reel) or a vibration-resistant base design. --- ## 3. Part Number Breakdown (Typical) To understand the specific encoding: * **HTX**: Series name (High-temperature, low impedance). * **63V**: Rated voltage (63 Volts). * **101**: Capacitance code (10 + 1 zero = 100µF). * **M**: Tolerance (±20%). * **HC5**: Case size code (Dimensions). * **Q-R2**: Packaging/Compliance code (RoHS, Tape & Reel). --- ## 4. Common Applications * **Automotive Electronics:** Engine Control Units (ECUs), LED lighting drivers. * **Industrial Power Supplies:** DC/DC converters and switching regulators. * **Telecommunications:** Base station power filtering where heat dissipation is a concern. ---
