  Working Voltage: 10V; Surge Voltage: Typically ~12.5V

• Tolerance: ±20% (Standard for electrolytic capacitors)

• Type: SMD Aluminum Electrolytic Capacitor
  (Polymer/Solid variants may exist; this spec is for standard wet electrolyte)

  Common SMD sizes: 6.3×5.8, 6.3×7.7 (check datasheet)

• Pitch / Lead Spacing: 2.5mm to 3.5mm (Standard SMD spacing)

• Temperature Range: -40°C to +105°C (General-purpose 105°C rating)

• Leakage Current: Low leakage (IL ≤ 0.01CV or 3µA after 2 minutes, typical)

• Equivalent Series Resistance (ESR): Moderate (varies by series; typically <1Ω)

• Polarity: Polarized – Negative terminal clearly marked on case body

• Quantity: 2 pieces

⚙️ Key Features:

• Surface-Mount Design: Enables high-density PCB assembly and automated manufacturing; ideal for compact, modern electronics.

• Moderate Capacitance: Effective for local decoupling of ICs, smoothing switched-mode power supply outputs, and general bypass/energy storage.

• Low-Profile: Fits into thin devices where through-hole components are not viable.

• High-Temperature Rating: 105°C rating ensures reliable operation in warmer environments and under load.

• Clear Polarity Marking: The black stripe with “-“ symbols indicates the negative (cathode) lead/pad.

📦 Typical Applications:

• Power Supply Filtering: Input/output filtering on DC-DC buck/boost converters, LDO regulators, and switching power supplies.

• IC & Microcontroller Decoupling: Placed near power pins of digital ICs, FPGAs, and MCUs to suppress high-frequency noise and provide localized charge storage.

• Audio Circuit Coupling: As a DC-blocking (AC-coupling) capacitor in audio amplifier stages and signal paths.

• Energy Buffer/Reservoir: Provides brief current bursts to components like motors, LEDs, or GSM modules without causing a significant voltage droop on the main supply rail.

• Consumer Electronics: Found in routers, set-top boxes, LED drivers, and USB-powered devices.

🔧 Mounting & PCB Design Notes:

1. Polarity is Critical: The marked side (negative) must connect to the lower voltage/GND. Reversing polarity will cause the capacitor to fail, often violently (venting or exploding).

2. PCB Footprint: Use the manufacturer-recommended land pattern to ensure proper soldering and mechanical stability. Common footprint for ~6.3mm diameter.

3. Soldering: Reflow or hand-solder with care. Avoid excessive heat exposure to prevent drying out the electrolyte.

4. Placement: For decoupling, place as close as possible to the power and ground pins of the target IC, with short, wide traces.

⚠️ Important Limitations & Care:

• Voltage Derating: For long-term reliability, operate at ≤80% of the rated voltage (e.g., ≤8V for a 10V capacitor) especially in high-temperature environments.

• Lifespan: Electrolytic capacitors have a limited lifespan (~2000-5000 hours at max temperature). Lifespan roughly doubles for every 10°C below the rated temperature.

• Not for Precision Timing: The ±20% tolerance and relatively high leakage make them unsuitable for precision analog timing or sampling circuits (use ceramic or film caps instead).

• ESR & Ripple Current: Ensure the capacitor’s ESR and ripple current ratings meet the requirements of your switching power supply to avoid premature failure.
