QAP2G474JRP, also known as film capacitors, is an electronic component used to store electrical energy. They are made of two conductive plates, one made of processed plastic film with an aluminum backed foil and the other of a metal core. This combination gives film capacitors properties such as stable capacitance, low loss, high insulation, vibration resistance, and higher frequency rating. They are commonly used for bypassing, blocking, tuning, DC filtering, and providing decoupling capability in many types of circuits.

The working principle behind film capacitors is based on a system of dielectric layers that act as isolators between the two conductive plates. The dielectric layers are made from different materials such as polyester, polypropylene, polyethylene, or paper. The material of the dielectric layers is chosen depending on the desired characteristics of the capacitor such as high voltage rating, low leakage current, and high temperature performance. They all contain a certain amount of dielectric loss, which is the amount of energy converted to heat during operation.

The QAP2G474JRP film capacitor is mainly used in automotive applications due to its high voltage ratings, low weight, and high reliability. Typically, these capacitors are used in applications such as sensors, audio circuits, motor controllers, power supplies, and ECUs. The capacitance range of these capacitors is typically between 0.47⁻¹¹ Farads to 4.7⁻⁶ Farads, depending on the application.

In automotive applications, QAP2G474JRP film capacitors are used for noise suppression and signal filtering.
