Film capacitors are types of capacitors that consist of a thin dielectric film, with two electrical connections that enable an electrical charge to be stored on them. The dielectric film itself is usually made from polyester, polycarbonate, polypropylene, polyethylene, polystyrene, or even air. The most common type of film capacitor is the polyester capacitor, due to its wide range of applications and its low cost. One excellent example of a film capacitor is the QAP2J155KRP.

The QAP2J155KRP is a radial-leaded, surface mount, low-voltage, plastic film capacitor. It is made from high dielectric strength polypropylene and is rated to operate at temperatures ranging from -50°C to +105°C. Additionally, it features very low equivalent series resistance (ESR) and insulation resistance is high, without self-heating.

The QAP2J155KRP is mainly used in audio applications, automation and control, consumer electronics, industrial applications, medical equipment, and telecommunications equipment. Its small size and high-performance characteristics make it an ideal component for these applications.

Working Principle of the QAP2J155KRP

The QAP2J155KRP works by acting as a storage medium for electrical charge. It is basically a two-terminal component which has a dielectric material, also known as an insulator, sandwiched between two conductors called “plates”. When a voltage is applied between the two plates, an electric field is generated that causes current to flow through it. This current is stored as electrical charge within the capacitor, and is proportional to the voltage applied.

When the voltage is removed, the charge remains stored in the capacitor, as long as it is not leaky, and can be discharged through a resistor. This ability to store and discharge electrical charge is what makes a film capacitor a crucial component in many electrical systems. The QAP2J155KRP has excellent performance characteristics that make it the ideal choice for such applications, particularly audio systems.

Conclusion

The QAP2J155KRP is a versatile and reliable plastic film capacitor that can be used for many different types of audio applications. It is highly-compatible, having a range of temperature as well as low equivalent series resistance and insulation resistance. This makes it a great option for many types of industrial, consumer electronics, medical, and telecommunications equipment.
