22uF 25V Electrolytic Capacitors (MINI)

• Electrolytic capacitors are widely used in switched-mode power supplies, DC-DC converters and power supplies. These capacitor are available in high capacitance and voltage rating than ceramic capacitors. The longer lead is the positive lead and the shorter lead is the negative lead, reversing the polarity of a electrolytic capacitor will damage the capacitor.

• 22uF 25V Through Hole Electrolytic Capacitor is a high quality capacitor which offers long life and high reliability. The capacitor contains an insulator between relative conductors in an electrode. Electrolytic Capacitors are most commonly used type of capacitors in Electronic Circuits.

Applications:

• Used in filter circuits like High/Low pass filter etc.
• Used in Resonant Circuits
• To remove noise from a circuit
• Used in DC-DC converters and Power supply circuits
• To Smoothen ripples in converters
• Fading LED circuits

When you see “25V in a 2.2µF, 25V electrolytic capacitor,” it indicates the following:

1. Capacitance Value: The capacitor has a capacitance of 2.2 microfarads (µF). This is the measure of the capacitor’s ability to store electrical charge.
2. Voltage Rating: The 25V indicates the maximum voltage that the capacitor can handle safely without the risk of breakdown or failure. This means you should not apply a voltage higher than 25 volts across the capacitor.
3. Electrolytic Type: Being an electrolytic capacitor, it is polarized, meaning it has a positive and a negative terminal. It is essential to connect it in the correct orientation in a circuit.

• The 25V is the maximum allowable voltage, and the 2.2µF is the capacitance value of the capacitor. Always ensure that the voltage applied does not exceed the rated voltage to prevent damage to the capacitor.
