Polyester Capacitor is made by depositing a thin layer of metal on both sides of the polyester film, which forms the electrodes. They have a high dielectric constant, which means they can store a large amount of charge per unit of volume. This makes them ideal for use in circuits that require high precision and stability, such as audio circuits, filters, and oscillators. Our products are highly stable and have a low dissipation factor, which means they don't generate much heat or lose much energy as heat.
