film capacitor

A capacitor that uses plastic film as the dielectric. It may also be referred to by the name of the specific material used, such as polyester (Mylar) capacitors. Its advantages include low variation in capacitance due to temperature and voltage, and high precision, making it often used in components that require high fidelity, such as measuring instruments, low-frequency filters, and audio circuits. However, it is not suitable for components that handle high-frequency currents, such as those in televisions and radios, due to its poor high-frequency characteristics.
