Low-voltage capacitors are essential components in a wide range of electronic devices, playing a critical role in energy storage, filtering, and signal coupling. These capacitors are designed to operate at lower voltage levels, making them suitable for various applications in consumer electronics, automotive systems, and industrial equipment. This article aims to explore popular low-voltage capacitor product models, providing insights into their specifications, applications, and the factors influencing their selection.
Low-voltage capacitors are classified based on their voltage ratings, typically ranging from a few volts to around 100 volts. They are crucial in applications where high voltage is not required, allowing for efficient energy storage and signal processing. Common applications include power supply circuits, audio equipment, and timing circuits.
