Film capacitors are passive electronic components that use a thin plastic or paper film as the dielectric material to store a static electrical charge. They are used in a wide range of applications, such as electronics circuits, signal processing, and AC power line filtering. Film capacitors provide superior performance characteristics compared to other types of capacitors, such as ceramic, electrolytic, and tantalum. They are also more reliable, and more resistant to extreme temperatures, moisture, and physical vibration. Film capacitors come in a variety of forms such as radial leads, axial leads, surface mount, and hermetic packages. Film capacitors can also be customized to meet specific requirements, such as size, capacity, and temperature range.
