21FD3703A-F application field

The 21FD3703A-F is a non-polarized, non-inductive capacitance element that has a wide range of applications. This type of capacitor is most commonly used in consumer electronic products, such as mobile phones, digital cameras, audio systems, computers, and other similar products. This particular model is capable of handling up to 1GHz and is suitable for use in high-frequency signal applications.

21FD3703A-F working principle

The 21FD3703A-F film capacitor stores electrical energy in an electrostatic field. When a voltage is applied, the dielectric material between the capacitor plates will be polarized, forming a negative and a positive layer. This creates an electric field between the plates, which stores electrical energy within the capacitor. The material of the dielectric also affects the capacitance of the capacitor. When the voltage is removed, the electric field will collapse, and the stored energy will be released.

The 21FD3703A-F is a highly reliable and stable capacitor as it is constructed using a polypropylene film with a low loss factor. The capacitor also features low equivalent series resistance and low dissipation factor. This allows it to produce accurate signals with high-frequency applications.

The 21FD3703A-F is a RoHS compliant device that is easy to mount and has a long life of up to 3000 hours at full rated voltage. This type of capacitor is durable and can operate at temperatures ranging from -40°C to 85°C or -40°F to 185°F.
