The part number **HTK-63V220MF80BQ-R2** refers to a high-performance **Conductive Polymer Hybrid Aluminum Electrolytic Capacitor**. These components are widely used in automotive and industrial electronics due to their low ESR (Equivalent Series Resistance) and high reliability. --- ### 1. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Capacitance** | 22 μF | | **Voltage Rating** | 63 VDC | | **Tolerance** | ±20% (M) | | **Case Size** | Φ6.3 x 8.0 mm (F80) | | **Technology** | Hybrid (Liquid Electrolyte + Conductive Polymer) | | **Temperature Range** | -55°C to +125°C | | **Endurance** | 4,000 to 10,000 hours (depending on series) | | **Packaging** | Tape & Reel (R2) | --- ### 2. Breakdown of the Part Number The nomenclature follows a specific logic used by manufacturers (like CapXon or similar high-reliability brands): * **HTK**: Series designation (typically High Temperature/Low ESR Hybrid series). * **63V**: Rated Voltage (63 Volts). * **220**: Capacitance code (22 followed by 0 zeros = 22μF). * **M**: Tolerance (M = ±20%). * **F80**: Case size dimensions (6.3mm diameter x 8.0mm height). * **BQ**: Terminal or specific construction style (usually Surface Mount / V-Chip). * **R2**: Packaging code (13" or 15" Reel). --- ### 3. Key Advantages 1. **Hybrid Construction**: By combining a solid polymer with a liquid electrolyte, this capacitor achieves the low ESR of polymer capacitors while maintaining the "self-healing" properties and low leakage current of standard aluminum electrolytics. 2. **Stable Performance**: Unlike standard electrolytic capacitors, the capacitance and ESR of hybrid types remain very stable across a wide range of temperatures and frequencies. 3. **High Ripple Current**: Capable of handling significant ripple currents, making it ideal for DC-DC converter output stages. 4. **AEC-Q200 Compliance**: Parts in the HTK series are frequently qualified for automotive use, ensuring high resistance to vibration and thermal shock. --- ### 4. Common Applications * **Automotive Electronics**: ECU power supplies, ADAS sensors, and lighting systems. * **Industrial Power**: DC-DC converters, motor drivers, and smoothing circuits. * **Telecommunications**: Base station power modules where high reliability in outdoor environments is required.
