Technical Specifications Table | Parameter | Specification | | :--- | :--- | | **Capacitance** | 220 µF | | **Voltage Rating** | 50 V DC | | **Tolerance** | ±20% (M) | | **Temperature Range** | -40°C to +125°C | | **Endurance (Life)** | 2,000 to 5,000 hours at 125°C (Series dependent) | | **Case Size (Code)** | F61 (Typically denotes 8x10.5mm or similar) | | **Mounting Type** | Surface Mount (SMD / V-Chip) | | **Termination** | Lead-Free / RoHS Compliant | --- ### 2. Part Number Breakdown Understanding the nomenclature helps in identifying the specific attributes: * **HTX**: The Series name. This is a **High Temperature** series, often characterized by low ESR (Equivalent Series Resistance) and high ripple current capability. * **50V**: The maximum working voltage (50 Volts). * **220**: The capacitance value in microfarads (µF). * **M**: The tolerance code (±20%). * **F61**: The case dimension code, defining the physical diameter and height of the SMD "can." * **R2**: Usually refers to the packaging style (Tape and Reel) or a specific revision/lead-free status. --- ### 3. Key Electronic Characteristics #### High Temperature Resilience Unlike standard capacitors rated for 85°C or 105°C, the **HTX** series is rated for **125°C**. This makes it ideal for automotive "under-the-hood" applications or high-density power supplies where heat buildup is significant. #### SMD (Surface Mount Device) Form Factor The "V-Chip" design allows this capacitor to be soldered directly onto the surface of a PCB. It features a plastic base plate to provide stability during vibration and to ensure proper alignment during automated pick-and-place assembly. #### Low ESR and High Ripple Current Because this is an electrolytic capacitor, it is used primarily for: 1. **Filtering:** Smoothing out voltage fluctuations in DC-DC converters. 2. **Decoupling:** Providing a local energy reservoir for integrated circuits. 3. **Bypassing:** Diverting AC noise to the ground. --- ### 4. Common Applications * **Automotive Electronics:** ECU (Engine Control Units), LED lighting drivers, and infotainment systems. * **Industrial Power Supplies:** Switching regulators and AC-DC converters. * **Telecommunications:** Base station equipment where reliability and heat dissipation are critical.
