Below is the detailed breakdown of its specifications and electronic characteristics. --- ### 1. Technical Specifications | Parameter | Specification | Details | | :--- | :--- | :--- | | **Capacitance** | 100 µF | Rated storage capacity | | **Voltage Rating** | 50V DC | Maximum working voltage | | **Series** | HTK | High temperature, high ripple current series | | **Tolerance** | ±20% (M) | Standard industry tolerance | | **Temperature Range** | -55°C to +125°C | Designed for extreme environments | | **Package / Case** | SMD (V-Chip) | Surface Mount Device | | **Size Code** | H10 | Refers to dimensions (approx. 8x10mm or 10x10mm) | | **Endurance** | 2,000 to 5,000 hours | Rated life at maximum temperature | --- ### 2. Part Number Decoder Analyzing the alphanumeric string helps identify the specific characteristics: * **HTK**: The Series name (High temperature, conductive polymer hybrid or low-ESR electrolyte). * **50V**: Rated Voltage (50 Volts). * **101**: Capacitance code. The first two digits are significant figures, the third is the multiplier (10 × 10¹ = 100µF). * **M**: Tolerance code (±20%). * **H10**: Case size dimensions (Diameter and Height). * **E**: Packaging/Modification code (often signifies RoHS compliance or specific lead-free plating). * **XN-R2**: Taping and reeling specification for automated pick-and-place machines. --- ### 3. Key Electronic Features * **Low ESR:** This series is engineered to have Low Equivalent Series Resistance, which reduces heat generation during high-frequency switching. * **AEC-Q200 Qualified:** Most parts in the HTK series are automotive-grade, meaning they can withstand high vibration and thermal cycling. * **Hybrid Technology:** Depending on the specific manufacturer line, HTK often utilizes a hybrid electrolyte (liquid + conductive polymer) to achieve both high voltage handling and extremely low ESR. --- ### 4. Common Applications Due to its high temperature rating and 50V capacity, this part is commonly used in: 1. **Automotive ECUs:** Power management for engine control units. 2. **DC/DC Converters:** Filtering input/output noise in power supplies. 3. **LED Drivers:** Smoothing rectified AC or high-frequency PWM signals. 4. **Industrial Automation:** Reliable performance in non-climate-controlled environments.
