What Is a Paper Capacitor?
A paper capacitor is an electronic component designed to store electrical energy by interleaving thin paper sheets and metal foil.
The capacitor’s insulation comes from the alternating layers of paper and metal foil, offering a compact and cost-effective solution. The use of relatively inexpensive materials like paper and metal foil enables the production of smaller capacitors at lower costs compared to other types. Furthermore, paper capacitors are noted for their high resistance to heat and moisture, making them well-suited for harsh environments or high-temperature applications. Nonetheless, they might not be ideal for high-voltage or high-frequency uses.
These capacitors are utilized in a wide range of applications, including electronic devices, communication equipment, power circuits, and filter circuits.
