The part number **HTX-63V101MHC5Q-R2** refers to a high-performance **Aluminum Electrolytic Capacitor**. These components are specifically designed for high-reliability applications, often featuring low impedance and high temperature resistance. --- ### 1. Technical Specifications Below is the breakdown of the technical parameters based on the standard naming convention for this series: | Parameter | Specification | | :--- | :--- | | **Capacitance** | 100 µF (101 code) | | **Voltage (Rated)** | 63V DC | | **Tolerance** | ±20% (M code) | | **Operating Temperature** | Up to +125°C (HTX High-Temp Series) | | **Mounting Type** | Surface Mount (SMD / V-Chip) | | **Service Life** | Typically 2,000 to 5,000 hours at max temp | --- ### 2. Part Number Decoder The alphanumeric string provides specific details about the component's construction: * **HTX**: Series designation (High temperature, low ESR, long life). * **63V**: Rated working voltage (Maximum voltage the capacitor can handle). * **101**: Capacitance value in picoFarads ($10 \times 10^1$ pF), which equals **100µF**. * **M**: Tolerance code (M = ±20%). * **HC5Q**: Case size and physical dimensions (specific to the manufacturer’s grid). * **R2**: Packaging code (usually indicates Tape & Reel for automated assembly). --- ### 3. Key Features & Applications This specific capacitor is built for demanding environments. #### Features * **Low ESR (Equivalent Series Resistance):** Minimizes heat generation and improves efficiency in power circuits. * **Vibration Resistance:** The SMD "V-chip" design often includes anti-vibration features for automotive or industrial use. * **Thermal Stability:** Rated for 125°C, making it suitable for areas with poor airflow or proximity to heat-generating components. #### Common Applications 1. **Automotive Electronics:** Engine control units (ECU) and infotainment systems. 2. **Power Supplies:** Output filtering in DC-DC converters. 3. **Industrial Automation:** Control boards requiring long-term reliability. 4. **LED Lighting:** Drivers that operate at high internal temperatures. --- ### 4. Comparison with Standard Capacitors Compared to a standard 85°C or 105°C capacitor, the **HTX** series offers: * **Better Longevity:** It degrades much slower under thermal stress. * **Higher Ripple Current:** It can handle more "noise" or AC current overlay without failing.
