QXP2J103KRPT

Film capacitors are comprised of a thin dielectric film which is densely wound between two metal electrodes. The film capacitor has a small physical size, a large quantity of capacitance, and superior stability when exposed to routine environmental conditions. These features have resulted in their wide usage in many applications. QXP2J103KRPT is one such example of a film capacitor from Murata, which is typically utilized in commercial or industrial areas where reliable performance is required.

Applications of QXP2J103KRPT

The QXP2J103KRPT film capacitor is designed to deliver consistent performance across a range of conditions, enabling it to be used in a variety of applications. As an example, this device is suitable for use in power supply circuits, as it can successfully dampen fluctuations, reduce resonance, and stabilise circuit performance. As a result, it is often found in conjunction with devices such as DC-DC step-down converters, and is also suitable for devices that require both high and low voltage control, due to its wide operating temperature range (-55°C to +125°C). On top of this, the low ESR and ESL of this capacitor mean it can be used for attenuation and filtering applications, for example AC/DC adapters and clean room equipment.

Working Principle of QXP2J103KRPT

The QXP2J103KRPT film capacitor works on the same principle as any other capacitor; it stores electrical energy within an electric field established between an electric conductive and insulative medium. The capacitance of this device is determined by its electrode size and the thickness of the dielectric film it is constructed from. This helps determine the amount of charge the device can store. Usually the crucial parameter when considering the performance of a film capacitor is losses, as this determines its ability to conduct and store charge. In the case of this device, it has low ESR and ESL values; the ESR is typically between 0.1 and 0.5 mΩ, and the ESL is typically between 0.3 and 3.0 nH. This is much lower than that of other film capacitors, which makes the QXP2J103KRPT well suited for demanding applications like filtering, DC/DC voltage converters and switching power supplies.
