The part number **506FSR360XZ2AB** refers to a high-performance **Supercapacitor** (also known as an Ultracapacitor) manufactured by **Illinois Capacitor** (now part of Cornell Dubilier/CDE). --- ### 1. Technical Specifications The part number follows a specific coding structure that defines its electrical and physical characteristics: | Property | Value | | :--- | :--- | | **Capacitance** | 50 Farads (50.0 F) | | **Voltage (Rated)** | 3.6 Volts DC | | **Tolerance** | -10% to +30% | | **ESR (Internal Resistance)** | ~30 mΩ (AC at 1kHz) | | **Temperature Range** | -40°C to +65°C | | **Mounting Type** | Through-hole (Radial Lead) | | **Termination Style** | PC Pins (XZ Configuration) | --- ### 2. Key Features * **High Energy Storage:** Unlike standard capacitors measured in microfarads ($\mu F$), this stores energy in whole **Farads**, allowing it to bridge the gap between batteries and traditional capacitors. * **Rapid Charge/Discharge:** It can handle millions of charge/discharge cycles without the degradation seen in chemical batteries. * **Low ESR:** The low internal resistance allows for high power delivery during peak demands. * **Multi-cell Design:** The "3.6V" rating indicates this is likely an assembly of multiple cells (typically two 1.8V or 2.7V cells) balanced in series within a single package. --- ### 3. Common Applications This specific supercapacitor is typically used in the following scenarios: 1. **Memory Backup:** Providing power to CMOS or RAM modules during a main battery swap or power outage. 2. **Pulse Power:** Assisting batteries in GSM/GPRS modules where high current bursts are required for transmission. 3. **Energy Harvesting:** Storing small amounts of energy from solar or vibration sources to power IoT sensors. 4. **Power Conditioning:** Smoothing out voltage fluctuations in sensitive industrial electronics. --- ### 4. Handling Precautions * **Polarity:** This is a polarized device. Reverse voltage can lead to leakage or permanent failure. * **Voltage Limits:** Do not exceed 3.6V. Even slight overvoltage significantly shortens the lifespan of the dielectric layer. * **Soldering:** Excessive heat during soldering can damage the internal seals. Use standard wave soldering or manual soldering with care.
