The part number **HT-63V220MF80Q-R2** refers to a high-temperature, radial leaded Aluminum Electrolytic Capacitor. This component is typically used for energy storage, filtering, and decoupling in power supply circuits. ### 1. Part Number Breakdown Based on standard industry naming conventions for electrolytic capacitors, here is the technical breakdown: | Segment | Code | Description | | :--- | :--- | :--- | | **Series** | HT | High Temperature / High Reliability series | | **Voltage** | 63V | Rated Working Voltage (63 Volts DC) | | **Capacitance** | 220M | 220µF (Microfarads); 'M' denotes ±20% tolerance | | **Size Code** | F80 | Physical dimensions (typically 8mm diameter x 11.5/12mm height) | | **Package** | Q-R2 | Packaging style (likely Taped or specific lead forming) | --- ### 2. Technical Specifications These are the general electrical characteristics associated with this specific part: * **Capacitance:** 220 µF * **Voltage Rating:** 63 VDC (Surge voltage is typically 1.15x this value) * **Tolerance:** ±20% (Standard for electrolytic capacitors) * **Operating Temperature:** Usually up to +105°C (The "HT" designation often implies extended life at high heat). * **Form Factor:** Radial Lead (through-hole mounting). --- ### 3. Application Use Cases This capacitor is designed for mid-range voltage applications where stability and heat resistance are required: 1. **Power Supply Filtering:** Smoothing out ripples in DC-DC converters or AC-DC adapters. 2. **Audio Circuits:** Coupling and decoupling where high-frequency noise needs to be mitigated. 3. **Industrial Electronics:** Used in motor controllers and LED drivers due to the 63V rating, which provides a safety margin for 24V or 48V systems. --- ### 4. Critical Considerations When using this part in a design, keep the following in mind: * **Polarity:** This is a polarized component. Connecting it backwards will lead to gas buildup and potential explosion/failure. * **ESR (Equivalent Series Resistance):** At 63V and 220µF, check the datasheet for the specific ESR value if using it in high-speed switching power supplies to avoid overheating. * **Lifetime:** Electrolytic capacitors have a finite lifespan defined in hours (e.g., 2,000 to 5,000 hours at 105°C).
