Film capacitors, also known as plastic film capacitors, are capacitors that possess a dielectric material made of a thin plastic film and are named by their materials. C4DENPQ5680A8TK is a type of film capacitor that is commonly used in electronic applications because of its reliable size and high voltage ratings. These capacitors are designed for applications where there will be large amounts of current. They are ideal when the employment of space-saving mounting is needed. The small size and large electric field strength make them suitable in areas such as power electronics, high performance audio amplifiers, electric motor drives and frequency inverters.

The C4DENPQ5680A8TK film capacitor is an axial-lead, polymer capacitor with aluminum-reinforced plastic film with a very low DF and high insulation properties. The capacitors are built to “self-heal” should their dielectric material fail or be damaged and continue operation. This self-healing feature is due to the low current draw of film capacitors, which is essential in order to function efficiently and safely.

The application fields of C4DENPQ5680A8TK film capacitors range from high voltage and high power applications, such as AC motor drives, AC motor drives inverters, air-conditioning equipment, generators, UPS and solar energy converters to low-voltage, low-noise audio applications. Furthermore, some applications are related to power conditioning and distribution, switches, contactors and relays, switchgear and dynamic braking systems.

The working principle of the C4DENPQ5680A8TK film capacitor is quite simple. It is a thin plastic film coated with a thin metal layer. The metal layer is usually an aluminum layer with an oxide layer that creates an oxide-aluminum combination to increase capacitance. The oxide layer allows electrons to move through it and causes the electric charge to build up on each side of the film, creating a capacitance between the two. This build-up of charge causes the voltage across the capacitor to increase, which is what produces the voltage regulation during operation.

The C4DENPQ5680A8TK film capacitor is an ideal choice for many applications because of its reliable size, high voltage ratings and its ability to self-heal in the case of dielectric failure. The wide application fields and simple working principle make this capacitor an optimal choice for power conditioning and distribution, switches, contactors, relays and dynamic braking systems, as well as AC motor drives, AC motor drives inverters, air-conditioning equipment, generators, UPS and solar energy converters.
