Film capacitors are a type of capacitor, which are effectively two electrical conductors separated by a thin dielectric layer, typically a plastic film. The capacitance of a capacitor is typically in the range of 1 to 1000 picofarads, and is determined by the size and thickness of the dielectric layer. The most commonly used type of film capacitors are known as Mica capacitors, which are made of a thin mica film sandwiched between two metal plates. Other film capacitors include ceramic capacitors, polyester capacitors and polypropylene capacitors.

The QXK2J474JTP is a type of film capacitor that is typically used in electronic circuits. It is a double-plate capacitor that consists of two aluminum plates with a mica dielectric layer between them. The plate insulation is a hard high-temperature polymer material. The outer coating of the plates is a polypropylene film. The maximum working voltage for the QXK2J474JTP is approximately 350 volts, and the maximum capacitance is 4700 picofarads.

The QXK2J474JTP is primarily used in power filter and decoupling circuits, where its high-frequency characteristics are beneficial. It is also sometimes used in audio crossover networks and amplifier circuits as a bypass capacitor. The QXK2J474JTP has excellent temperature stability, low losses, and a consistent capacitance over a wide range frequency range.

The working principle of the QXK2J474JTP is based on the dielectric layer between two metal plates. When a voltage is applied to the plates, it causes electrons to flow between the two plates. This creates an electric field in the dielectric layer, which causes an ionic charge imbalance in the dielectric. This charge creates a capacitance effect, which results in the plates acting like a capacitor.

The QXK2J474JTP is a useful and versatile component for a wide range of electronic applications. Its versatile design and excellent temperature stability make it a popular choice for use in high-voltage power applications, while its low losses and broad frequency range give it the characteristics necessary to be used in audio and video circuits.
