100 µF 25V Electrolytic Capacitors

Wiring Connections:

• Positive Terminal: Marked with a ‘+’ sign on the capacitor body. Connect this terminal to the positive voltage supply or circuit node.
• Negative Terminal: Marked with a ‘-‘ sign. Connect this terminal to the ground or negative voltage supply.

To connect the capacitor:

• Step 1: Identify the positive and negative terminals of the capacitor. The positive terminal is  longer and marked with a ‘+’ sign.
• Step 2: Connect the positive terminal to the positive side of your circuit or power supply.
• Step 3: Connect the negative terminal to the ground or negative side of the circuit.
• Step 4: Ensure proper polarity is maintained to avoid capacitor damage or malfunction.

Power:

• Voltage Rating: The capacitor is rated for 25V DC. Do not exceed this voltage to prevent damage or failure.
• Capacitance: 100 µF, which is suitable for various applications requiring moderate capacitance.

Input and Output:

• Input: The input to the capacitor is the electrical power applied across its terminals.
• Output: The output is the stored electrical charge, which can be used to smooth voltage fluctuations, filter signals, or provide temporary power.

Physical Characteristics:

• Size: Compact size,  10 mm to 16 mm in diameter and 20 mm to 30 mm in height, depending on the manufacturer and specific model.
• Shape: Cylindrical with two leads for through-hole mounting.
• Housing: Encased in an aluminum can with a plastic or resin coating to protect the internal components.

Technical Specifications:

• Capacitance: 100 µF (microfarads), which determines the amount of charge it can store.
• Voltage Rating: 25V DC, indicating the maximum voltage it can handle without breakdown.
• Tolerance: ±20%, meaning the actual capacitance can vary by this percentage.
• Leakage Current: Low leakage current, important for maintaining accuracy in applications.

Additional Features:

• Polarized: Requires correct polarity for operation; the positive and negative terminals must be connected correctly.
• High Efficiency: Designed to handle various electronic applications where filtering and decoupling are needed.
• Durable: Built to last in a wide range of operating conditions, including varying temperatures.

How to Use:

• Step 1: Identify the capacitor’s positive and negative terminals. The positive terminal is usually longer or marked with a ‘+’ sign.
• Step 2: Insert the capacitor into the circuit, ensuring that the positive terminal goes to the positive voltage supply and the negative terminal goes to ground or the negative side.
• Step 3: For through-hole capacitors, insert the leads into the PCB (Printed Circuit Board) holes and solder them securely.
• Step 4: For surface-mount capacitors, place the capacitor on the PCB surface and solder the leads to the designated pads.
• Step 5: Check the polarity before powering up the circuit to prevent damage.
• Step 6: Use the capacitor for applications such as smoothing out voltage variations, filtering signals, and decoupling power supply noise.

The 100 µF 25V electrolytic capacitor is a versatile and essential component in electronics, valued for its ability to provide significant capacitance in a compact size. Its applications range from power supply filtering to signal processing, where stable and reliable performance is crucial. Proper handling and correct connection are key to ensuring optimal functionality and longevity of the capacitor in various electronic circuits.
