Capacitor 47uf/25V (Pack of 5)

Capacitor 47uf/25V (Pack of 5) Capacitor 47μF/25V Overview A Capacitor 47uf/25V is a versatile and widely used component in electronic circuits. These capacitors are typically electrolytic, meaning they have a higher capacitance per unit volume compared to other types like ceramic or film capacitors. This makes them ideal for applications where space is limited but a relatively large capacitance is required. Key Features and Specifications Capacitance: 47 microfarads (μF) Voltage Rating: 25 volts (V) Type: Electrolytic Polarization: Polarized, with a marked positive and negative lead Temperature Range: Typically -40°C to +85°C, though some can go up to +105°C Applications Power Supply Filtering: Electrolytic capacitors like the 47μF/25V are commonly used in power supply circuits to smooth out the ripple voltage. This helps in providing a more stable DC output from an AC input or a switching power supply. Decoupling and Bypassing: These capacitors are often placed in parallel with power lines close to ICs (integrated circuits) to decouple the power supply. This helps in reducing noise and ensuring that the ICs receive a clean and stable voltage. Timing Circuits: In conjunction with resistors, electrolytic capacitors are used in timing circuits for applications such as delays and oscillators. Their ability to store and release charge over a period is essential in these configurations. Audio Circuits: Capacitors in this range are used in audio circuits for coupling and decoupling signals. They block DC components while allowing AC signals to pass, thus maintaining signal integrity in audio applications. Installation and Considerations Polarity: Unlike non-polarized capacitors, electrolytic capacitors must be installed with the correct polarity. The negative lead is usually marked with a stripe and must be connected to the lower voltage side of the circuit. Reversing the polarity can cause the capacitor to fail, potentially leaking or even exploding. Voltage Rating: The 25V rating indicates the maximum voltage the capacitor can handle. It’s crucial not to exceed this voltage to avoid damaging the capacitor. In practice, it’s often recommended to use a capacitor with a voltage rating higher than the maximum voltage it will encounter in the circuit for added reliability. Physical Size: Electrolytic capacitors come in various sizes. Ensure that the chosen capacitor fits within the physical constraints of your project. The size generally increases with capacitance and voltage rating. Conclusion The 47μF/25V capacitor is a staple in many electronic designs due to its high capacitance and small size. Its applications range from power supply filtering and decoupling to audio processing and timing circuits. Proper installation, particularly observing polarity and voltage ratings, ensures reliable performance. Whether you’re building a power supply, an audio amplifier, or a timing circuit, the 47μF/25V electrolytic capacitor is likely to be a key component in your design toolkit. https://computronicslab.com/product/smoke-detector-system-using-mq135-and-stm32/
