QAP2G475KRP

Film capacitors are ubiquitous in all types of electronic devices. Film capacitors, specifically the QAP2G475KRP series, have a wide range of applications due to their dependable capacitance, low ESR, and long life. The QAP2G475KRP series film capacitors are used in a variety of applications ranging from power supplies, to car audio systems, to high-end audio equipment.

The QAP2G475KRP series capacitors feature a rugged polypropylene film construction, providing an excellent arc and flashover performance. With an insulation resistance of >50 GΩ, these capacitors can be used in high voltage applications. The capacitors are rated at 250VAC, with a maximum temperature rating of 105°C. The QAP2G475KRP series capacitors offer excellent electrical performance with a low ESR and high ripple current rating.

The working principle of film capacitors are that of dielectric polarisation. Film capacitors are manufactured by sandwiching two dielectric layers of plastic or paper together, with conductive electrodes attached to each layer close to the outside. When a voltage is applied across the capacitor, electrons move from one electrode to the other, resulting in a charge separation across the capacitor’s dielectric layers. This generates an electric field which allows for energy storage.

The QAP2G475KRP film capacitors provide superior performance compared to other types of capacitors for applications that require a relatively high capacitance and low ESR. These capacitors also offer excellent arc and flashover performance, providing enhanced protection from high voltage applications. With a dependable capacitance, high working voltage, low ESR, and excellent arc and flashover protection, the QAP2G475KRP series is an ideal choice for applications ranging from power supplies, car audio systems, to high-end audio equipment.
