Technical Specifications Table | Parameter | Specification | Details | | :--- | :--- | :--- | | **Capacitance** | 1000 µF | Energy storage capacity | | **Voltage Rating** | 25V DC | Maximum continuous operating voltage | | **Tolerance** | ±20% (M) | Standard industry tolerance | | **Temperature Range** | -55°C to +125°C | High-temperature stability (HTK series) | | **Endurance** | 2,000 to 5,000 hours | Rated life at maximum temperature | | **Mounting Type** | SMD (Surface Mount) | V-Chip configuration | | **Case Size** | Often 10x10.2mm | Physical dimensions (Check datasheet for exact) | --- ### 2. Part Number Breakdown (Typical Coding) Most manufacturers use a structured naming convention for these components: * **HTK**: Series name. Usually denotes **High Temperature** and **Low Impedance** characteristics. * **25V**: Rated Voltage (25 Volts). * **102**: Capacitance code. The first two digits are significant figures, the third is the multiplier ($10 \times 10^2 = 1000$ µF). * **M**: Tolerance code (M = ±20%). * **HHEXQ**: Case size and internal packaging internal codes (e.g., diameter and height). * **R2**: Tape and Reel packaging specification. --- ### 3. Key Electronic Characteristics #### A. Low ESR (Equivalent Series Resistance) This capacitor is engineered to have low internal resistance, which minimizes heat generation during high-frequency switching. This makes it ideal for DC-DC converters. #### B. High Ripple Current Handling The "HTK" series is built to withstand significant ripple current, which is essential for filtering noise in power supplies for automotive ECUs (Electronic Control Units). #### C. AEC-Q200 Compliance Components with these specific long-string suffixes are frequently **AEC-Q200 qualified**, meaning they have undergone rigorous stress testing for vibration, thermal shock, and moisture resistance required for automotive environments. --- ### 4. Common Applications * **Automotive Electronics:** Power steering modules, LED lighting drivers, and infotainment systems. * **Industrial Automation:** Power filtering in PLCs and sensor arrays. * **Telecommunications:** Base station power modules where high-temperature stability is required. ---
