• Rated Voltage (VDC): 25V

• Tolerance: ±20% (Standard for electrolytics)

• Type: Aluminum Electrolytic, Radial Leads

• Temperature Range: -40°C to +85°C or +105°C (common)

• Leakage Current: Very Low

• Equivalent Series Resistance (ESR): Low to Moderate

• Lead Spacing: Typically 2mm, 2.5mm, or 3.5mm

• Diameter x Height: Small size, approx. 5mm x 11mm (common)

• Polarity: Polarized – Negative (-) lead is shorter; stripe/band on can indicates negative side.

• Quantity: 2 pieces

⚙️ Key Features:

• High Voltage Margin: The 25V rating provides excellent durability and longevity for 5V, 9V, and 12V circuits.

• Compact Size: Small form factor saves valuable PCB real estate.

• Cost-Effective: An inexpensive solution for achieving stable capacitance in power and signal applications.

• Reliable Performance: Widely used in consumer electronics, ensuring proven performance.

• Easy Mounting: Radial leads allow for straightforward vertical PCB mounting.

📦 Typical Applications:

• Power Rail Decoupling: Placed near IC power pins (microcontrollers, op-amps, logic chips) to filter high-frequency noise.

• Audio Coupling (DC Blocking): Used between amplifier stages to pass AC audio signals while blocking DC offset.

• Voltage Regulator Stabilization: On the input and output of linear regulators (e.g., 78xx series) to ensure stability and reduce ripple.

• Timer & Oscillator Circuits: In 555 timer circuits or RC networks where precise timing is not critical.

• General Bypass/Filtering: Across power supplies to smooth out minor voltage fluctuations.

🔧 Mounting & Polarity:

1. Polarity is Critical: The negative (-) lead is shorter and aligns with the colored stripe or band on the capacitor body. The PCB will have a + marking for the positive pad.

2. PCB Insertion: Insert leads into the correct polarity pads. The capacitor typically stands vertically on the board.

3. Voltage Derating: For long-term reliability, it’s good practice to use a capacitor with a voltage rating at least 1.5 to 2 times your circuit’s maximum voltage. For a 12V circuit, 25V is a safe choice.

⚠️ Important Limitations & Care:

• Polarity Warning: Reversing voltage will cause the capacitor to fail, potentially leaking or bursting. Always verify polarity before soldering.

• Lifespan: Electrolytic capacitors degrade over time, especially when exposed to heat. Operating at lower temperatures significantly extends lifespan.

• Not for Precision Timing: Due to the ±20% tolerance and temperature sensitivity, avoid using in precision RC timing circuits. Use ceramic or film capacitors instead.

• Leakage Current: While low, it can affect very high-impedance circuits.
