Film capacitors have become essential components in microwave, communications and electronic systems due to their robust construction, excellent electrical performance and wide variety of applications. The 21FD3735 is an example of a film capacitor specifically designed for tuning applications in broadcasting and telecommunications industry.

In general, film capacitors are constructed using two flexible dielectric films that are rolled around a spindle. The film is then covered with metal and treated to create a dielectric material that is able to withstand pressures while maintaining its insulation properties. The films used vary depending on the application, but typically can be polyester, polypropylene, polycarbonate, or polyethylene terephthalate. The 21FD3735 film capacitor uses a polyester dielectric material.

The 21FD3735 is a film capacitor specifically designed for tuning applications in broadcasting and telecommunications industry. The capacitor is designed with a non-magnetic metallic enclosure and is hermetically sealed for superior protection against external influences. The design features a low peak-to-peak distortion and low noise level, making it perfect for filtered or tuned applications. The capacitor is also designed with a curved, low-resonant design that helps reduce noise and detrimental electromagnetic interference.

The working principle of the 21FD3735 is relatively simple. When a voltage is applied to the capacitor’s terminals, an electrical field is created between the two inside its body. This causes the dielectric material to charge and bound between the terminals, forming an electrical and mechanical connection. This connection forms an electric charge between the two terminals, creating a capacitance. This capacitance can be maintained for various periods of time depending on the voltage applied. The 21FD3735 is designed to maintain its capacitance for up to 30 minutes, making it ideal for both short and long-term tuning applications.

The 21FD3735 film capacitor is an ideal component for use in broadcasting and telecommunications industry due to its robust construction, excellent electrical performance, and wide variety of applications. The non-magnetic metallic enclosure and hermetic sealing make it an excellent choice for filtered or tuned applications in these industries. For tuning specifically, the 21FD3735 is able to maintain its capacitance for up to 30 minutes, allowing for precise and accurate tuning that is required for these applications.
