Film capacitors are a form of non-polarized capacitor that offer excellent stability, dry-out resistance, and specific capacitance values in low voltage applications for power conditioning and other specialty uses. The QXK2G334JTP7FM, specifically, is a film capacitor specifically designed to meet the needs of low voltage and medium voltage applications. It offers enhanced voltage stability and low equivalent series resistance (ESR) values.

The QXK2G334JTP7FM is designed for use in medium voltage applications, including, but not limited to, AC/DC power supplies, instrumentation, and appliance circuits. Its non-polarized design also makes it suitable for applications that require bidirectional device operation. It is also used in solar inverter, electric motor and switch control, and induction heating circuits, where its high voltage stability and low ESR values provide enhanced performance.

The QXK2G334JTP7FM features an axial lead design, making it suitable for both through-hole and surface mount applications. It has an atypically high temperature working range from -40 to +105 Celsius, making it ideal for operating in harsh environmental conditions. It also features a wide capacitance range of 0.0022 to 0.0039 μF, a voltage rating of 5,000 volts, and a nominal capacitance at 20 kHz of 1μF. Furthermore, it has Very Low ESR (0.12 Ohms max) and offers a high degree of stability over temperature.

The working principle of the QXK2G334JTP7FM is based on its construction. It consists of two layers of film, typically polyester (PET), polypropylene (PP), or polyethylene terephthalate (PEN) film, separated by an electrolytic paste. The two layers of film are rolled or folded together and encapsulated in a plastic or plastic/foil casing with solderable lead wires. The film serves as the dielectric layer between the two electrodes, while the electrolytic paste creates a conductive trellis that connects the two layers of film.

When a voltage is applied, the electric field between the electrodes induces charges on the dielectric film. This causes a displacement current to flow between the two electrodes, which is known as capacitance. The magnitude of this current is proportional to the applied voltage and the capacitance of the film. The voltage rating of the QXK2G334JTP7FM is determined by the breakdown voltage of the electrolyte paste. When the voltage exceeds this value, the dielectric film is damaged and an arc is created.

In summary, the QXK2G334JTP7FM is a film capacitor designed for low voltage and medium voltage applications. It offers enhanced voltage stability, low ESR values, and a wide temperature operating range. The working principle of the device is based on its construction, which consists of two layers of film and an electrolytic paste, which enables it to store energy when a voltage is applied. This makes it a suitable choice for a variety of applications, including solar inverter, electric motor and switch control, and induction heating circuits.
