Film Capacitors

Film capacitors (also known as plastic film capacitors, film dielectric capacitors, polyester capacitors and polypropylene capacitors) have become increasingly popular in modern day electronics. They are especially well-suited for use in AC circuits due to their low impedance and low capacitance drift at high frequencies, as well as excellent dielectric absorption and insulation resistance. The SMC7.3473J100K35TR12 capacitors are one of the most popular varieties of film capacitors manufactured by Smartsumitomo.

Construction

A film capacitor consists of two metallic strips or plates separated by an insulating polymeric film. The two plates are usually connected to two external terminals or leads which are used to connect the capacitor to the rest of the circuit. The two plates and the insulating film form the core of the capacitor, while the external terminals consist of conductive conductors such as aluminium or steel. The films used in the construction of film capacitors can be made from polyester, polypropylene, polycarbonate, polytetrafluoroethylene, polystyrene, polyimide, among others. The insulating films act as the dielectric material for the device, and are responsible for the capacitors electrical properties.

Working Principle

The working principle of film capacitors is simple. When a voltage is applied across the two conducting plates of the capacitor, electrons move from one plate to the other until a displacement of charge occurs. This displacement of charge causes a current to flow in the circuit and creates an electric field between the two plates. The magnitude of the electric field depends on the amount of charge that has been displaced and the size of the capacitor. The electric field , in turn, creates an opposing electric field, this is what stores the electrical energy for the capacitor. When the electrical charge stored in the capacitor reaches the maximum value the current ceases to flow in the circuit and the capacitor is said to be \'fully charged\'. The stored charge can be discharged later by providing a path for the stored charge to go from the capacitor.

Applications of SMC7.3473J100K35TR12

The SMC7.3473J100K35TR12 film capacitor is a popular choice for many applications due to its wide temperature range (-25 to 70 degrees centigrade) and high vibration resistance. It is commonly used in electronic circuits in power system filtering and coupling, radio frequency oscillators and filters, as well as in frequency conversion, power supply and energy storage. For most applications the SMC7.3473J100K35TR12 are well-suited due to their low ESR (Equivalent Series Resistance), low dielectric absorption, high insulation resistance and low inductance. They can also be used for high-frequency coupling, such as for AC circuits, for which their capacitance remains constant even when subjected to varying voltages.In summary, film capacitors provide a reliable, effective and cost-efficient option for circuit protection and energy storage. The SMC7.3473J100K35TR12 film capacitors from Smartsumitomo is one of the most popular varieties, offering superior features and benefits for a variety of applications in modern day electronics.
