Technical Specifications Below are the primary electrical and physical characteristics of this specific part number: | Parameter | Value / Specification | | :--- | :--- | | **Capacitance** | 470 µF | | **Voltage Rating** | 35V DC | | **Tolerance** | ±20% (M) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Case Size (Code)** | H10 (typically 8x10.5 mm or 10x10.5 mm depending on series) | | **Temperature Range** | -55°C to +105°C | | **Life Cycle** | High Reliability / Long Life (often 2000–5000 hours) | | **Lead-Free Status** | RoHS Compliant | --- ### 2. Part Number Breakdown While naming conventions vary slightly by manufacturer (often related to brands like Lelon or similar high-quality Asian manufacturers), the string typically decodes as follows: * **HTK**: Series designation (typically indicates **High Temperature** or **Low Impedance**). * **35V**: Rated working voltage (Maximum continuous voltage the part can handle). * **471**: Capacitance code ($47 \times 10^1$ pF is not the case here; in electrolytic naming, this usually represents **470 µF**). * **M**: Tolerance code ($\pm 20\%$). * **HHEXQ**: Internal manufacturing codes for case dimensions, electrolyte type, and packaging style. * **R2**: Tape and Reel packaging specification. --- ### 3. Key Electronic Features * **Low ESR (Equivalent Series Resistance):** Designed to handle ripple current efficiently without excessive self-heating. * **Polarized Nature:** As an electrolytic capacitor, it has a positive and negative terminal. Incorrect installation can lead to component failure. * **Self-Healing:** The aluminum oxide dielectric layer can repair minor defects during operation. * **Reflow Soldering Compatible:** Built to withstand the high temperatures of automated SMD soldering ovens. --- ### 4. Common Applications * **DC-DC Converters:** Used for smoothing output voltage. * **Automotive Electronics:** Power filtering for infotainment or lighting modules. * **Industrial Power Supplies:** General-purpose decoupling to reduce noise on power rails. * **Consumer Electronics:** Power adapters and chargers.
