QXT2J683KRP7FR application field and working principle

Film capacitors are very versatile components and are often used in many different applications. QXT2J683KRP7FR is one such popular film capacitor model from the renowned manufacturer Kemet. It is a low cost general purpose film capacitor that is used in many power supplies, motors and appliances. This model has a wide range of applications and can be used in applications ranging from general purpose power supplies, motor drives, HVAC, lighting, communications, medical, and industrial equipment.

The QXT2J683KRP7FR is a low voltage, high capacitance film capacitor that is designed for low impedance applications. It is a non-polarized capacitor with a voltage rating of 250VAC/VDC. The capacitance range is wide, from 0.0022 to 10 μF, and its capacitance temperature coefficient is between 0.03 and 0.08%. The working temperature range of the QXT2J683KRP7FR is -40 to +85°C and it is rated for up to 2000 hours of life at 85°C.

The QXT2J683KRP7FR is a polyethylene-naphthalate (PEN) film capacitor. It is a molded film capacitor, which means that its design and construction is very compact. This makes it especially suitable for use in applications where space is limited. The PEN film allows this Capacitor to provide excellent characteristics such as high dielectric strength, good frequency response, and excellent capacitance stability.

The Working Principle of QXT2J683KRP7FR is very simple. When a voltage is applied to the capacitor, the electrical field in the two plates produces an electrical field across the dielectric. This causes the electrons to build up on one plate and be repelled away from the other plate. A stable electrical current then passes between the two plates, which is then delivered to the relevant circuit.

The QXT2J683KRP7FR provides a low leakage current, because a thick PEN film is used as its dielectric. It has a high insulation resistance and it is suitable for use in low impedance environments. It also offers good voltage stability over temperature changes, so it can be used in a variety of applications.

In conclusion, the QXT2J683KRP7FR is a very versatile film capacitor that can be used in many applications where high capacitance, low impedance, and excellent electrical characteristics are needed. Its compact design also makes it excellent for applications where space is limited. Its high dielectric strength, good frequency response, and excellent capacitance stability make it an ideal choice for many applications.
