Introduction to Low Voltage Capacitors<\/h2>\n<p>Low voltage capacitors are electrical components designed to store and release electrical energy in circuits operating at voltages up to 1,000 volts AC or 1,500 volts DC. They are essential for power factor correction, harmonic filtering, voltage regulation, and energy storage in industrial, commercial, and utility applications. These capacitors improve the efficiency of electrical systems by reducing reactive power, lowering electricity bills, and enhancing the lifespan of equipment. Common types include metallized polypropylene film capacitors, electrolytic capacitors, and ceramic capacitors, with ratings ranging from microfarads (\u00b5F) to farads (F). The global low voltage capacitor market is driven by increasing demand for energy efficiency, renewable energy integration, and smart grid infrastructure.<\/p>\n<h2 id=\"toc-55afac33b278a7af8dc7016b891c35ec\">2.
